CHAPTER VIII

+FISTULAE; FISSURES; SINUSES; ABSCESSES; FURUNCLES; ULCERS+

A +Fistula+ (pl. fistulae) is an abnormal communication between the

surface and an internal part of the body, or between two natural

cavities or canals. The first form is seen in a rectal fistula, the

second in vesicovaginal fistula. Fistulae may result from a congenital

defect and can arise from sloughing, traumatism and suppuration.

Fistulae are named from their situation and communication.

A +Fissure+ is a crack and in podiatry, has special reference to a

condition found in the toeweb.

A +Sinus+ is a tortuous track opening usually upon a free surface and

leading down into the cavity of an imperfectly healed abscess. A sinus

may be an unhealed portion of a wound. Many sinuses may be due to pus,

burrowing subcutaneously. A sinus fails to heal because of the

presence of some irritant fluid (as saliva, urine) or, because of the

existence of some foreign body, as dead bone, a bit of wood, a bullet,

a septic ligature, or because of rigidity of the sinus wall, which

rigidity will not permit collapse. The walls of a tubercular sinus are

lined with a material identical with the pyogenic membrane of a cold

abscess. Sinuses may be maintained by want of rest (muscular

movements) and by general ill-health.

+Treatment.+ In treating a fistula, remove any foreign body; lay the

channel open, curet, touch with pure carbolic acid, and pack with

iodoform gauze. In obstinate cases, entirely extirpate the fibrous

walls; sew the deeper parts of the wound with buried catgut sutures,

and approximate the skin surfaces with interrupted sutures of silkworm

gut. Fresh air is necessary; nutritious food and tonics must be

ordered.

+Acute Abscesses.+ An abscess may be defined as a circumscribed cavity

of new formation, containing pus. An essential part of this definition

is the assertion that the pus is in a cavity of new formation; is an

abnormal cavity; hence pus in a natural cavity (pleural or synovial)

constitutes a purulent effusion, and not an abscess, unless it is

encysted in these localities by walls formed of inflammatory tissue.

An acute abscess is due to the deposition and multiplication of

pyogenic bacteria in the tissues or in inflammatory exudates.

When abscesses form in an internal organ or in some structure which is

not loose like connective tissue, for instance, in a lymphatic gland,

a mass of pyogenic bacteria floating in the blood or lymph, lodges,

and these bacteria, by means of irritant products, cause coagulation

necrosis of the adjacent tissue and inflammatory exudation around it.

The area of coagulation necrosis becomes filled with white blood

cells, and the dry necrosed part is liquefied by the cocci.

Suppuration in dense structures causes considerable masses of tissue

to die and to be cast off, and these masses float in the pus.

An abscess heals by the collapse of its walls, and the formation of an

abundance of granulation tissue; in many cases granulations of one

wall join those of the other side, the entire mass of granulations

being converted into fibrous tissue, and this tissue contracting,

heals by third intention. If the walls do not collapse, the abscess

heals by second intention.

+Symptoms.+ The symptoms of an acute abscess may be divided into (1)

local, (2) constitutional. Locally there is intensification of

inflammatory signs; swelling enormously increases; the discoloration

becomes dusky; the pain becomes throbbing, and the sense of tension

increases; the cutaneous surface is seen to be polished and edematous,

and after a time, pointing is observed and fluctuation can be

detected. The constitutional symptoms are usually limited to chills

and fever, depending upon the severity of the infection.

+Treatment+ is free incision and drainage. The wound should be opened

early, if possible even before pointing or fluctuation, to prevent

destruction, subfascial burrowing, and general contamination; drainage

is continued until the discharge becomes scanty, thin and

seropurulent.

+Chronic Abscess+ is a term referring only to time. Usually a tubercular

abscess is designated as a chronic, cold, or scrofulous abscess. It is

an area of disease produced by the action of the tubercular bacilli

and is circumscribed by a distinct membrane. The symptoms present no

inflammatory signs. Constitutional symptoms are trivial or absent

unless secondary infection occurs. The treatment of these cold

abscesses depends upon their location.

+A Furuncle or Boil+ is an acute and circumscribed inflammation of the

deep layer of the skin and the subcutaneous cellular tissue, following

on bacterial infection of the hair follicle through a slight wound (by

scratching, shaving), with the staphylococcus pyogenes aureus.

+Symptoms.+ The symptoms of a boil are as follows: a red elevation

appears, which stings and itches; this elevation enlarges and becomes

dusky in color, a pustule forms that ruptures and gives out a very

little discharge which forms a crust; inflammatory infiltration of

adjacent connective tissue advances rapidly, and the boil in about

three days consists of a large red, tender, and painful base, capped

by a pustule and some crusted discharge. In rare instances, at this

stage, absorption occurs, but in most cases the swelling increases,

the discoloration becomes dusky, the skin becomes edematous, the pain

severe, and the centre of the boil becomes raised. About the seventh

day rupture occurs, pus runs out, and a core of necrosed tissue is

found in the centre of a ragged opening. The hair follicle and the

sebaceous gland, which have undergone necrosis, are found in this

core. Healing by granulation will occur; the constitution often shows

reaction during the progress of a boil.

Boils may be either single or multiple, and the development of one

boil after another, or the formation of several boils at once, is

known as _furunculosis_.

+Treatment.+ The treatment consists of crucial incision and the

application of a wet dressing.

+An Ulcer+ may be defined as the loss of substance due to necrosis of a

superficial structure, and the causes of ulcers may be divided into

(1) predisposing and (2) exciting. In the former, age, sex, occupation

and social condition have to be considered. The exciting causes are

traumatism and infection.

The chief varieties of ulcers seen on the leg and foot are as follows:

indolent or callous; varicose; tubercular; syphilitic;

epitheliomatous; diabetic; perforating and blastomycotic.

In indolent or callous ulcer, the cause may be divided into general

and local. Among the former may be mentioned typhoid fever, chronic

nephritis, anemia, poor hygiene, improper food, overwork, and lack of

sleep. Local causes: old scar tissue, extremes of heat or cold,

irritation of the tissues, injury, the presence of a foreign body such

as dead bone, splinter, etc.

+Symptoms.+ The most common location of these callous ulcers is on the

inner side of the lower third of the leg. They show a great variety in

size, shape, appearance and base, edges and surrounding area, and in

accordance with these differences, many different names are applied to

them. The size varies from a small ulcer less than one centimeter in

diameter, sometimes found with varicose veins, to the large

ulcerations which surround the leg and are called _annular_ ulcers.

The shape may be round, very irregular, or funnel shaped. The base may

be much or slightly depressed, or the granulations may be at a higher

level than the surrounding edges. When the granulations are large,

irregular, and bleed easily, they are spoken of as _exuberant_; when

pale, soft and flabby, as _weak_ or _edematous_; when small and slowly

growing, as _indolent_.

A peculiarly painful form of chronic ulcer is found over the internal

malleolus, and most frequently in women of middle age; it is often

associated with menstrual disorders and is known as a _congested_ or

_irritable_ ulcer. It begins as a small area of congestion over the

internal malleolus, which gradually increases in size and becomes dark

and more dusky in the centre, due to the deposit of blood pigment

caused by chronic congestion. The skin next becomes hard, dry, scaly

and pigmented, while the subcutaneous tissues lose their elasticity,

becoming inflexible, hard and adherent to the deeper structures. Then,

as a result of slight traumatism or even without injury, the centre of

the area breaks down and an ulcer develops. It may be circular or

irregular in shape and may be quite deep or superficial. The edges are

sharply cut, and both base and edges are bound down to the deeper

tissues. The intense pain of the ulcers is supposed to be due to

pressure upon the terminal nerve filaments in the dense sclerotic

tissue. This form of ulcer is very often difficult to cure and shows a

tendency to return after healing.

+Treatment.+ This naturally depends upon the time the ulcer is seen and

the conditions present. If there is considerable inflammation,

accompanied by marked cellulitis and pain, the milder wet dressings,

such as boric acid or Thiersch are indicated. Rest, of course, is the

most important factor. The patient must be prohibited from walking,

and if necessary, the movements of the neighboring joints must be

prevented by the application of suitable splints. After the acute

inflammatory symptoms have subsided the granulations must be

stimulated, (see Chapter XIX).

+Varicose Ulcer.+ To chronic ulcers of the leg associated with varicose

veins, especially of the smaller venous radicles, the name varicose

ulcer has been given.

+Symptoms.+ The usual development of this variety of ulcer is as

follows: persons who suffer from varices of the leg usually complain

for some time before the external manifestation of the disease, of a

deep aching pain in the limb, with a sense of weight, fullness, and

fatigue. In a more advanced state of the disease, the ankles swell

after a day’s hard work, and the feet are constantly cold; an

embarrassed state of the circulation is denoted by these symptoms and

the deep seated veins begin to swell. After a time, which varies with

the idiosyncrasy and occupation of the patient, small soft, blue

tumors are seen at different points of the leg, most of them

disappearing on pressure, but returning when this pressure is removed

or when the patient stands up. Each little tumor is caused by a vein

dilated at the point at which it is joined by the intramuscular

branch. Around many of these tumors a number of minor vessels of a

dark purple color are clustered, these being the small superficial

veins which enter the dilating vein and in which the varicose ulcer is

often of a brownish blue color, due to a deposit of pigment.

Frequently a leg, which is the seat of varicose veins, or which is

edematous from other causes, is attacked by acute eczema. The

recognition of varicose ulcers is usually easy but the mere presence

of enlarged veins, it should be noted, is not pathognomonic, because

they may often exist along with ulcers of other origins, tuberculous,

syphilitic, etc.

The surface of varicose ulcers usually presents imperfect and

unhealthy granulations, secreting a more or less thin and offensive

pus, and the granulations are sometimes covered with membranous

exudation. The edges and base are thickened and callous, and enlarged

veins, capillary or otherwise, are present near the circumference and

often amount to genuine blood tissue which tunnels the infiltrated

tissues. In examining such an ulcer one gets the impression of a great

pigmented scar, the centre of which has broken down.

Lymphangitis and venous thrombosis are not of infrequent occurrence in

connection with varicose ulcers, while embolism and even pyemia are

sometimes in evidence. Among the most frequent complications is

cellulitis, and this may sometimes be so severe as to necessitate

operation. Erysipelas may also occur in cases of varicose ulcer, and

hemorrhage is a common and serious complication and has at times been

fatal.

or neosalvarsan.

+Treatment.+ The treatment of varicose ulcers must be based on

antiseptic cleanliness, and the improvement of nutrition by

improvement of the circulation of the blood and lymph. Then again the

treatment will vary according to the time when the ulcer is first seen

by the surgeon. In aggravated ulcers, especially those accompanied by

crusts, foul smelling discharges and various inflammatory conditions,

the leg should be washed once or twice daily with soap and water,

cleansed with a piece of sterile gauze, and shaved when necessary.

Warm applications should be employed such as Wright’s solution, boric

acid; Thiersch and the stronger antiseptics are uncalled for, as they

often induce eczema. Under such treatment, in most cases, the swelling

and irritation will subside and the ulcer will become clean and more

healthy in appearance, especially if the patient be confined to bed

with elevation of the limb. Rest always seems to the patient a useless

waste of time, but in reality time is thus saved. It is by far the

most important point in the treatment of ulcers of the leg in which

poor circulation is a factor, but the plan must be carried out

consistently in order to obtain the best results. The condition does

not admit of occasionally walking about the house or of sitting in a

chair. However, when circumstances do not permit of the recumbent

position, the veins can be supported in various ways. Bandages of

plain rubber, or rubber cloth, or cloth woven and rendered elastic by

the character of mesh, or elastic stockings, or flannel, gauze, or

muslin bandages, can be used. It is preferable to use flannel bandage

(see Therapeutic measures) for the reasons mentioned. The best means

of obtaining the support, however, is by the use of Unna’s Paste. The

technic and application of this method of treatment has also been

described (Therapeutic measures).

Operations upon varicose veins are frequently called for in aggravated

cases, provided the general condition of the patient permits. Briefly,

these many consist in multiple ligations, in ligation of the internal

saphenous alone, in extirpations of large or small sections of

varices, in circumcision of the skin above the ulcer, or of the ulcer

itself, tying all the veins and reuniting the cuticle. However, it

must not be forgotten that in the presence of an ulcer, infection of

an operative wound is likely to occur.

+Syphilitic Ulcers+ may result from pustules or they may begin as

tertiary sores. They occur frequently where the integument is thin or

where the part is kept moist by the natural secretions. The deep

ulcers of tertiary syphilis develop from gummata. These are variously

sized deposits largely made up of large spheroidal cells and a few

giant cells. They are poorly supplied with blood vessels and undergo

coagulation necrosis, but do not tend to suppurate until infected.

Sooner or later the overlying skin becomes involved, either with or

without a pyogenic infection, and the gumma sloughs out leaving the

typical syphilitic ulcer. A protozoa microbe (Schaudinn’s and

Hoffmann’s organism) is now the recognized cause of syphilis. It is

called the _spirochaeta pallida_ or _treponema pallidum_.

+Symptoms.+ When a syphilitic ulcer develops it usually assumes one of

two types, superficial or deep. The former may appear comparatively

early in the disease. It usually varies in size from a quarter to a

half dollar piece, has a circular outline, sharply cut, indurated

edges, and a dirty greenish base. The deep ulcers result from the

breaking down of gummata. They are, at the beginning, surrounded by a

reddened area of inflammation, the small ones being crater like, with

punched out edges, the larger ones having overhanging, thin, soft,

inflamed edges. The base is indurated, of a dusty red color and dirty

or sloughing in appearance, the slough being often of a greenish

color. The discharge is thin, frequently bloody, and contains debris

from the broken down gumma. The surrounding skin is indurated, of a

dusky red color and dirty or sloughing in for some time, they loose

their characteristic appearance and take on the form of simple chronic

ulcers. The scar remaining is characteristic. It is thin, of a dead

white color, pigmented here and there, and when pinched it wrinkles

like tissue paper. Thin form of syphilitic ulcer is found most

frequently on the upper third of the leg. When ulcers are accompanied

by enlarged veins, it is extremely difficult at times to make a

differential diagnosis between a luetic ulcer and one of a varicose

type. The chief differential points are as follows:

_Location_:

Varicose ulcers, the lower third of the leg.

Syphilitic ulcers, the middle and upper third of the leg.

_Appearance_:

Varicose, irregular, not undermined, granulations reddish.

Syphilitic, typical punched out edges, sharp, and undermined,

greyish discharge, thin and watery.

_Number_:

Varicose usually single.

Syphilitic, multiple, having a tendency to coalesce and form

one large ulcer.

A very important point to remember is that a syphilitic ulcer, once

healed, usually remains so. At times it is extremely difficult, even

in view of the different points already mentioned, to make a distinct

diagnosis between a varicose and a syphilitic ulcer; then the

Wasserman reaction should be resorted to, but too much stress should

not be placed upon its findings. It may happen that a patient having a

suspected luetic ulcer is given mercurial treatment with the result

that the reaction is negative, but this should not exclude the

possibility of syphilis existing. A positive Wasserman in a case of

chronic ulcer with enlarged veins which refuses to heal, warrants a

diagnosis of a syphilitic lesion. In a great many cases the Noguchi

luetin skin reaction is of great aid in establishing a diagnosis.

+Treatment.+ The treatment is both local and general. As regards local

treatment, if the ulcer secretes freely, either the black wash or a

solution of bichloride, varying from 1 to 5000 to 1 to 10000 should be

employed. Where there is very little discharge, calomel powder is

indicated. In addition, it is understood that a firm compression

bandage be applied (especially in those cases complicated with

enlarged veins) beginning at the base of the toes and carried up to

the knee.

The general treatment consists of the intravenous injection of

salvarsan or neosalvarsan (10 grains), or the intramuscular injection

of bichloride of mercury, one quarter of a grain, or 10 minims of a 10

per cent. suspension of salicylate of mercury. In addition, mercurial

rubs and the administration of iodides and mercury internally are

advised.

+A Tuberculous Ulcer+ usually results from the bursting through the skin

of a tuberculous abscess. The base is, soft, pale and covered with

feeble granulations, and gray shreddy sloughs. The edges are of a dull

blue or purple color and gradually thin out toward their free margins,

and in addition, are characteristically undermined, so that a probe

can be passed for some distance between the floor of the ulcer and the

thinned out borders. At times the edges are solid and puckered, being

scarlike in character. Thin, devitalized tags of skin often stretch

from side to side of the ulcer. The outline is irregular, small

perforations often occur through the skin and a thin watery discharge

containing shreds of tuberculous debris escapes. The ulcer is usually

superficial and very little pain is present. At times it is crusted

over, the crust being thin and of a brown or black color. Again it may

be progressing at one point and healing at another. It is slow in

advancing but often proves very destructive. The scars left by its

healing are firm and corrugated, but are apt to break down.

+Treatment.+ The local treatment calls for special mention. If the ulcer

is of limited extent, the most satisfactory method is complete removal

by means of the knife, scissors, or sharp spoon, of the ulcerated

surface and of all of the infected area around it, so as to leave a

healthy surface from which granulations may spring. If the raw surface

left is likely to result in cicatricial contraction, skin grafting

should be employed.

The general treatment should consist of tonics, plenty of fresh air,

and a good nutritious diet. Bowels must be regulated.

+Perforating Ulcer of the Foot+ occurs in connection with lowered

resisting powers of the tissues, due usually to some lesion of the

nerves or vessels. The ulcer is circular in shape, painless, with

callous borders, and eats progressively into the deeper tissues and

bones, and has little or no tendency to heal.

+Etiology.+ Although formerly looked upon as a specific disease,

perforating ulcer is now known to depend upon many local and general

conditions of which it is occasionally a more or less accidental

manifestation. The various theories as to its immediate causation may

be divided into: (1) mechanical, (2) vascular, (3) nervous, (4) mixed.

+The Mechanical Theory+ regards injury as the sole cause, due in most

instances to the pressure or rubbing of a shoe. If this explanation

were adequate, however, such ulcers would be extremely common, while

in reality they are rare.

+The Vascular+ theory assumes that arteriosclerosis is always present,

and causes ischemic necrosis through arterial and capillary

thrombosis.

+The Nerve+ theory, which is the one most commonly accepted, is that

perforating ulcer is always of trophic origin and depends upon a

chronic peripheral neuritis. In support of this assertion, attention

is called to certain interstitial and parenchymatous alterations

frequently demonstrable in the nerves of the affected part. It must

not be forgotten, however, that these nerve changes may be due to

secondary disturbances in nutrition, depending upon arteriosclerosis

as in senile, diabetic, and other forms of gangrene.

+According to the Mixed Theory+ either vessels or nerves, or both may be

at fault. It admits that traumatism is an important factor, although

seldom if ever an exclusive cause. Perforating ulcer is observed in

connection with various diseases and conditions, the most prominent

of which are locomotor ataxia, fractures of the spine, injuries of

the cord, diabetes, spina bifida, syringomyelitis and injury and

division of the peripheral nerves. Perforating ulcer from lesions of

the central nervous system is comparatively rare and it is doubtful if

it is ever due to embolism or to ligation of the arteries.

The three most prominent causes, therefore are, (1) affections of the

spinal cord (2) injuries of the peripheral nerves and (3) diabetes.

This variety of ulcer is seen more frequently in males than in

females, and it is almost exclusively confined to adults, especially

between the ages of forty and sixty. Occupations requiring standing or

walking are strong predisposing causes, provided a tendency to the

disease exists. A poor fitting shoe and deformities of the foot giving

rise to excessive pressure or irritation, are of much importance in

determining the appearance and location of the ulcer. It rarely

appears in children, unless it is associated with spina bifida.

+Symptoms.+ Perforating ulcer has a marked tendency to develop where

pressure and irritation are greatest, which is almost always upon the

sole of the foot at the junction of the great or little toe with the

metatarsus. It may occur, however, upon the heel, the sides of the

foot, the plantar surface of any portion of the great toe, or even

upon the centre of the sole, these unusual situations being most

commonly found associated with diabetes. When talipes or hammertoe

exists, the ulcer is apt to occur wherever pressure is pronounced,

even upon the dorsum of the foot or the ends of the toes. Usually but

one foot is affected, although both feet may be involved, in which

case the disease is termed symmetrical.

Three stages may be recognized in the development of the ulcer: (1)

the formation of callosities, (2) superficial ulceration, (3) deep

ulceration. Very frequently in tabes and in diabetes, a purulent

blister is the first indication of trouble, but usually a marked

epithelial thickening, in the form of a corn or a bunion, is the

initial symptom. Sooner or later the centre of a callosity breaks

down into a bluish, unhealthy, indolent, superficial ulcer, secreting

a small quantity of watery pus, and with an offensive odor. The sore

is circular as though punched out of the callous tissue, the latter at

times so thickened and overhanging that the ulcer is almost concealed

beneath it. There is little or no tendency to heal, even under

exacting treatment, and if recovery should take place, a speedy

relapse is the rule, even with the patient remaining in bed. The

indolent and foul ulcer tends to eat deeply into the adjacent tissues,

progressively involving bursae, tendons, muscles, joints, and bones. A

deep round hole results, which may even perforate the foot. The most

striking symptoms are chronicity, stubborn resistance to treatment,

and the absence of pain and tenderness.

The fact that perforating ulcer is so often found in connection with

lesions of the nervous system accounts for the abnormalities of

sensation, motion and reflexes which accompany it. This explains the

various trophic disturbances which are very often observed, such as

epithelial growth, not only in the vicinity of the ulcer, but

occasionally over the entire foot and leg; also eczema, erythema and

excessive perspiration. The nails are frequently thickened and

distorted and the subcutaneous cellular tissues are so changed as even

to suggest elephantiasis. Inflammatory complications, sometimes

serious, are not uncommon owing to infection through the ulcer, and an

ascending neuritis may even result in myelitis. Gangrene from

arteriosclerosis is also frequently seen.

+Treatment+ in those predisposed to diabetes and tabes, deserves

prophylaxis consideration. The shoes must fit accurately and without

undue pressure; much walking is to be avoided; when ulceration has

begun the recumbent position and cleanliness are of paramount

importance. The callous epidermis should be removed so as to render

the ulcer as superficial as possible. Dead bone must be scraped away

or extracted, if in the form of a sequestrum, and drainage must be

perfected by enlarging the opening. Sinuses should be enlarged and

any pockets found should be thoroughly opened. It must be emphasized,

however, that operative interference should be undertaken with care

and discretion in order to avoid necrosis and infection. Periodic

curettments and cauterizations with silver nitrate are often of

benefit, as are also the employment of dry iodoform gauze as a

packing, together with the occasional use of various moist dressings.

Both the constant and interrupted currents of electricity have been

resorted to with benefit, sometimes locally and sometimes applied to

the spinal cord or affected nerves. Measures directed to the

improvement of the circulation of the foot, such as massage,

stimulating baths, and lotions, are of service.

_Bier’s Arterial Hyperemia_, in the form of baking of the foot by

means of a gas or electric apparatus, especially devised for the

purpose (Tyrnauer) is of great benefit, more so when there is a

neuritis accompanying the ulcer. The baking should be done once a day

for from ten to twenty minutes, and the temperature should be

gradually increased from 100°F. to 300°F., depending upon the

patient’s ability to tolerate heat.

The passive, venous or obstructive form of hyperemia is absolutely

contraindicated in this class of ulcers. The initial cause of the

trouble must receive attention, because upon its successful management

depends the cure, much more so than upon the local measures.

Diabetics and syphilitics should receive appropriate treatment. The

bad cases, especially where gangrene or serious infection exists, may

require amputation, but unless this can be done in sound tissue with

adequate innervation, a perforating ulcer may develop upon the area

exposed to the pressure of an artificial limb. Resection of joints is

usually of little benefit. The most satisfactory operative results in

this class of ulcers have been obtained by stretching the posterior

tibial nerve, together with scraping the ulcer, or, better, by

excising it, followed by immediate suture of the wound. The operation

is best done through a curved incision beneath the internal

malleolus, the nerve being isolated and vigorously stretched in both

directions by means of some blunt instrument inserted beneath it.

Sometimes the external or internal plantar nerve alone is treated in

this manner.

+Blastomycotic Ulcer.+ This is not a common condition in the lower

extremity. It is found near the lower third of the leg, and begins as

a papule or papulo-pustule, soon becoming covered with a crust which,

on removal, discloses a papillomatous area. The typical ulcer is

elevated, verrucous or fungating, with a soft base which is

infiltrated with a seropurulent secretion. The border is dark-red or

purple and slopes more or less abruptly through the normal skin, from

which it is sharply defined. The quickest and most positive method of

differentiation is by means of the tissues. The organisms are fungi,

known as the blastomycetes, saccharomyces or yeasts, characterized

especially by their mode of multiplication or cell division, called

budding.

+Treatment.+ In all cases, thorough cleansing of the ulcer with

antiseptic lotions, as previously described, is of great benefit.

Complete extirpation of the ulcerative lesions has been successful,

but curetting does not always prevent their recurrence. Potassium or

sodium iodide in large doses (totaling from 100 to 400 grains per day)

and radiotherapy seem to be the most efficacious forum of treatment.

Copper sulphate in a 1 per cent. solution as a wash for external use

and also in one quarter of a grain doses internally, has in some cases

given good results.

+Epitheliomatous Ulcer.+ In none of the more common ulcerative skin

lesions would the conditions for the development of cancer seem to be

more favorable than in chronic dermatitis with ulceration; the

despised and neglected varicose ulcers of the leg. The extreme

chronicity of the inflammatory process, often lasting for many years;

the age of the patient, which is usually advanced; the almost

inconceivable neglect of the lesion in many cases, so that the

persistent presence of foul and decomposing secretion and of the

products of tissue necrosis is common: the frequent absence of even

an attempt at cure; the fact that most of these patients are compelled

to be on their feet all day and thus keep up and increase the

unfavorable conditions; and, finally the circumstance that in many of

them the added history of alcoholism, of renal or cardiac

disabilities, or of other chronic affections is also present; all of

these factors would lead to the presumption that in this ulcerative

lesion, above all others, carcinomatous degeneration would be the most

common.

While so few instances of cancer secondary to varicose ulceration are

seen, it rarely appears before the age of forty. It is usually seen

where varicose ulcers as well as the scars they produce are found. The

base of the characteristic ulcer is hard, nodular and irregular, made

up of firm warty granulations, and often covered with sloughs. It

bleeds easily and has a foul discharge. The edges are hard and

everted. The borders and base present a peculiar and striking

thickness and hardness, as though the ulcer were imbedded in

cartilage, while the granulations feel firm and appear red and warty.

The amount of pain, the involvement of neighboring lymphatic glands

and the rate of growth vary. Epitheliomata which have developed from

congenital warts, moles, or nevi are apt to be very malignant. When

epitheliomatous degeneration occurs in a chronic ulcer, it first

begins to get hard about the edges, which become everted and gradually

bound down to the deeper tissues. The granulations about the margins

become large, red, nodular, hard and bleed very readily. This

condition spreads over the entire ulcer, which assumes a sloughing and

foul character. The diagnosis is confirmed by the microscopic

examination of a section cut from the edge of the ulcer.

+Treatment.+ Malignant ulcer can be cured only by the destruction or

removal of the new growth. For its treatment, caustics with or without

curetting, excision or radiotherapy may be employed. The best caustics

are arsenic, chloride of zinc, caustic potash and formalin.

The objections to this method are the extreme pain; the lack of

certainty as to the removal of all of the neoplasm; the fact that the

lymphatics and glands are not dealt with, as well as the fact that

unless the treatment is thorough, the growth is stimulated rather than

retarded. The scar is also apt to be unsightly. Without doubt excision

forms the best method of treatment. The incision should be wide of the

ulcer, and all indurated tissues and any lymphatics or glands that are

involved must be removed.

In some cases it may be necessary even to amputate the leg in order to

effect a cure. The X-rays from the Coolidge tube are to be

recommended, as the cross fire effect of these rays in some cases is

of great benefit. Recently radium has been used in these ulcers of the

leg with good results. The gamma rays are to be preferred as they are

more penetrating and should be applied two or three hours a day for a

number of days. At least from 50 to 200 milligrams of radium bromide

must be used in order to obtain any effect. Recently beta rays have

been found to be as effective as the gamma rays. In order to prevent a

radium burn the rays have to be filtered before they are applied.
