The tumefied portions of the check and lip are pale, hard, unctuous,

and glistening. They are rarely very painful, and often painless. On

palpation a hard and rounded nodule one or two centimeters in diameter

can be detected deep in the central portion of the swollen cheek.

From the third to the sixth day a small, black, dry eschar, circular or

oval, becomes formed at the most prominent and most livid portion of

the swelling, whether cheek or lip. This gradually extends in

circumference for a few days or for a fortnight, sometimes taking in

almost the entire side of the face or even extending down to the neck.

As it enlarges the tissues around become circumscribed with a zone

intensely red. The internal eschar extends equally with the external

one. Eventually, the {341} eschar separates, in part or in whole, and

becomes detached, leaving a hole in the cheek through which are seen

the loosened teeth and their denuded and blackened sockets.

During this time the patient's strength remains tolerably well

maintained, as a rule, until the gangrene has become well advanced.

Intelligence usually remains good. Many children sit up in bed and

manifest interest in their surroundings. Others lie indifferent to

efforts made for their amusement. Some exhibit insomnia and delirium.

The pulse is small and moderately frequent, rarely exceeding 120 beats

to the minute until near the fatal close, when it often becomes

imperceptible. Appetite is often well preserved, unless pneumonia or

other complications supervene, but thirst is often intense, even though

the tongue remain moist. The desire for food sometimes continues until

within a few hours of death. Toward the last the skin becomes dry and

cold, diarrhoea sets in, emaciation proceeds rapidly, collapse ensues

and death.

Death usually occurs during the second week, often before the complete

detachment of the eschar--in many instances by pneumonia, pulmonary

gangrene, or entero-colitis. Some die in collapse, which is sometimes

preceded by convulsions. When the eschars have become detached,

suppuration exhausts the forces of the patient, and death takes place

by asthenia.

The complication most frequent is pneumonia, and the next

entero-colitis. Gangrene of the lungs, of the palate, pharynx, or

oesophagus, of the anus, and of the vulva, may supervene. Hemorrhage

from the facial artery or its branches has been noted as an exceptional

mode of death (Hueber), the rule being that the arteries in the

gangrenous area become plugged by thrombi, and thus prevent hemorrhage.

Recovery may take place before the local disease has penetrated the

cheek--indeed, while the mucous membrane alone is involved. In recent

instances, however, the disease does not subside until after the loss

of considerable portions of the cheek, and the child recovers with

great deformity, not only from loss of tissue in the cheek and nose,

but from adhesions between the jaws and the cheek.

PATHOLOGY AND MORBID ANATOMY.--Gangrenous stomatitis always involves

the cheek, almost always that portion in proximity to the mouth. It is

almost invariably unilateral. Either side seems to be equally liable.

Both sides suffer only, it is contended, when the gangrene is limited

in extent, confined to the mucous membrane, and occupies the sides of

the frenums of the lips (Barthez et Rilliet). It usually if not

invariably begins in the mucous membrane, as a phlyctenular

inflammation, which undergoes ulceration, followed by gangrene,

immediately or not for several days, and then becomes covered with a

more or less brownish-gray eschar. The ulceration of the mucous

membrane is occasionally preceded by an oedematous condition of the

cheek externally, similar to that sometimes observed in ordinary

ulcerous stomatitis; but this is not the characteristic circumscribed,

tense infiltration observed later. This ulceration is situated most

frequently opposite the junction of the upper and lower teeth.

Sometimes it proceeds from the gingivo-buccal sulcus of the lower jaw,

sometimes from the alveolar border of the gums. It extends in all

directions, and often reaches the lower lip. From three to sixteen days

may be consumed in these extensions. The {342} surrounding mucous

membrane becomes oedematous. The ulceration soon becomes followed by

gangrene, sometimes within twenty-four hours, sometimes not for two or

three days, and exceptionally not for several days. The ulcerated

surfaces bleed readily, change from gray to black, and become covered

with a semi-liquid or liquid putrescent detritus. They are sometimes

surrounded by a projecting livid areola, which soon becomes gangrenous

in its turn. The shreds of mortified membrane, though clinging a while

to the sound tissues, are easily detached, and often drop spontaneously

into the mouth. Meanwhile, there is abundant salivation, the products

of which pour from the mouth, at first sanguinolent, and subsequently

dark and putrescent and mixed with detritus of the tissues. Large

portions of the gums, and even of the mucous membrane of the palate,

may undergo destruction within a few (three to six) days. The

gangrenous destruction of the gums soon exposes the teeth, which become

loose and are sometimes spontaneously detached. Thence the periosteum

and bone become implicated and undergo partial denudation and necrosis,

and portions of necrosed bone become detached if the patient survives.

The characteristic implication of the exterior of the cheek becomes

manifest from the first to the third day, but occasionally not until a

day or two later. A hard, circumscribed swelling of the cheek or cheek

and lip occurs, sometimes preceded, as already intimated, by general

oedematous infiltration. The surface is tense and unctuous, often

discolored. In its central portion is an especially hard nucleus, one

to two centimeters or more in diameter. Gangrene often takes place at

this point from within outward at a period varying from the third to

the seventh day or later. The skin becomes livid, then black; a pustule

is formed at the summit of the swelling, which bursts and discloses a

blackened gangrenous eschar from less than a line in thickness to the

entire thickness of the cheek beneath. The area of gangrene gradually

extends. The dead tissues become detached, and a perforation is left

right through the cheek, through which are discharged saliva and

detritus. Meanwhile, the submaxillary glands become swollen and the

surrounding connective tissue becomes oedematous. In some instances,

however, no change is noticeable in these glands.

Examinations after death have shown that thrombosis exists for some

distance around the gangrenous mass. Hence the rarity of hemorrhage

during the detachment of the eschar.

DIAGNOSIS.--In the early stage of the disease the main point of

differential diagnosis rests in the locality of the primitive lesion,

the mucous membrane of the inside of one cheek. Subsequently there is

the gangrenous odor from the mouth; the rapid peripheric extension of

the local lesion, which acquires a peculiar grayish-black color; its

rapid extension toward the exterior of the cheek or lip; the

tumefaction of the cheek, discolored, greasy, hard, surrounded by

oedematous infiltration, and presenting a central nodule of especial

hardness; then the profuse salivation, soon sanguinolent, subsequently

purulent and mingled with detritus of the mortified tissues. Finally,

the eschar on the exterior of the swollen cheek or lip leaves no doubt

as to the character of the lesion. From malignant pustule it is

distinguished by not beginning on the exterior, as that lesion always

does (Baron).

PROGNOSIS.--The prognosis is bad unless the lesion be quite limited

{343} and complications absent. At least three-fourths of those

attacked perish; according to some authorities fully five-sixths die.

The objective symptoms of the local disease are much more important in

estimating the prognosis than are the constitutional manifestations,

the vigor of the patient, and the hygienic surroundings, although, as a

matter of course, the better these latter the more favorable the

prognosis. Prognosis would be more favorable in private practice than

in hospital or asylum service.

TREATMENT.--Active treatment is required, both locally and

constitutionally. Local treatment is of paramount importance, and alone

capable of arresting the extension of the process of mortification. The

topical measure in greatest repute is energetic cauterization with the

most powerful agents, chemical and mechanical--hydrochloric acid,

nitric acid, acid solution of mercuric nitrate, and the actual cautery,

whether hot iron, thermo-, or electric cautery. The application of

acids is usually made with a firm wad or piece of sponge upon a stick

or quill, care being taken to protect the healthy tissues as far as

practicable with a spoon or spatula. After the application the mouth is

to be thoroughly syringed with water to remove or dilute the

superfluous acid. Hydrochloric acid has been preferred by most

observers.

As these cauterizations must be energetic to prove effective,

anæsthesia ought to be induced. Should ether be employed for this

purpose, hydrochloric acid or the acid solution of mercuric nitrate

would be selected of course.

In the early stages these agents are to be applied to the inside of the

cheek, so as to destroy all the tissue diseased, if practicable, and

expose a healthy surface for granulation. Should the exterior of the

cheek become implicated before cauterization has been performed or in

spite of it, it is customary to destroy the tissues from the exterior,

including a zone of apparently healthy surrounding tissue. As the

gangrene extends, the cauterization is to be repeated twice daily or

even more frequently. After cauterization the parts are dressed with

antiseptic lotions, and antiseptic injections or douches are to be used

frequently during day and night to wash out the mouth and keep it as

clear as possible from detritus.

Meigs and Pepper report beneficial results from the topical use of

undiluted carbolic acid, followed by a solution of the same, one part

in fifty of water, frequently employed as a mouth-wash. The progress of

the sloughing was checked and the putridity of the unseparated dead

tissue completely destroyed in the two cases mentioned by them, one of

which recovered quickly without perforation of the cheek. Gerhard

preferred undiluted tincture of the chloride of iron; Condie, cupric

sulphate, thirty grains to the ounce. Bismuth subnitrate has recently

been lauded as a topical remedial agent.[13]

[Footnote 13: Maguire, _Medical Record N.Y._, Feb. 3, 1883.]

The mouth should be frequently cleansed by syringing, douching,

spraying, or washing with disinfectant solutions, such as chlorinated

soda liquor, one part to ten; carbolic acid, one to twenty. Lemon-juice

is sometimes an agreeable application, as in some other varieties of

stomatitis. Constitutionally, tonic and supporting treatment is

demanded, even in those instances where the appetite is well maintained

and the {344} general health apparently well conserved. Soups, milk,

semi-solid food, egg-nog, egg and wine, wine whey, milk punch,

finely-minced meat, should be administered as freely as the state of

the digestive functions will permit. If necessary, resort should be had

to nutritive enemata. Quinia and tincture of chloride of iron are the

medicines indicated. When sufficient alcohol cannot be given with the

food, it should be freely exhibited in the most available form by the

mouth or by the rectum. The apartment should be well ventilated, the

linen frequently changed, the discharges promptly removed.

Toxic Stomatitis.

DEFINITION.--An inflammation of the interior of the mouth due to

poisoning, especially by drugs, and chiefly by mercury, copper, and

phosphorus.

Mercurial Stomatitis.

DEFINITION.--An inflammation of the mucous membrane of the mouth,

eventually ulcerating, the result of systemic poisoning by the

absorption of mercury.

SYNONYMS.--Stomatitis mercurialis; Mercurial ptyalism, Ptyalismus

mercurialis; Mercurial salivation, Salivatio mercurialis.

ETIOLOGY--Predisposing and Exciting Causes.--Special vulnerability to

the toxic influence of mercury, and special proclivity to inflammatory

affections of the mouth and the organs contained therein, are the

predisposing causes of mercurial stomatitis. The exciting cause is the

absorption of mercury into the tissues of the organism. The

susceptibility of healthy adults is much greater than that of healthy

children. The susceptibility of adults varies very greatly.

Constitutions deteriorated by prolonged disease, undue exposure, and

the like are much more promptly influenced in consequence. Tuberculous

subjects do not bear mercury well.

Idiosyncratic susceptibility to toxæmia by mercurial preparations is

now and then encountered in practice, and instances have been

published[14] in which fatal results have ensued, after prolonged

suffering, from the incautious administration of a single moderate dose

of a mercurial drug.

[Footnote 14: For example, see in Watson's _Practice of Physic_ a case

of furious salivation following one administration of two grains of

calomel as a purgative, the patient dying at the end of two years, worn

out by the effects of the mercury and having lost portions of the

jaw-bone by necrosis.]

Until comparatively recent years the most common cause of mercurial

poisoning was the excessive employment of mercurial medicines, whether

by ingestion, inunction, or vapor bath. Topical cauterization with acid

solution of mercuric nitrate is likewise an infrequent, and usually an

accidental, cause of the affection. Elimination of the mercury by way

of the mucous glands of mouth and the salivary glands proper excites

the stomatitis in these instances. An entirely different series of

cases occur in artisans exposed to handling the metal and its

preparations or to breathing its vapor or its dust. In these instances

the poison may gain {345} entrance into the absorbent system by the

skin, the mucous membranes of the nose, mouth, and throat, the stomach,

or the lungs. No matter what care may be exercised in cleansing the

hands, it is often impossible to prevent occasional transference of the

noxious material from fingers to throat, or to thoroughly free the

finger-tips under the nails. The avocations entailing the risks of

mercurial stomatitis comprise quicksilver-mining, ore-separating,

barometer- and thermometer-making, gilding, hat-making, manufacturing

of chemicals, and exhausting the globes employed in certain forms of

electric illumination.[15] The slow absorption of mercury into the

bodies of artisans induces in addition serious constitutional nervous

disturbances--tremors, palsy, etc.

[Footnote 15: _Med. and Surg. Reporter_, Philada., Dec. 30, 1883, p.

734.]

SYMPTOMATOLOGY, COURSE, DURATION, TERMINATIONS, COMPLICATIONS, AND

SEQUELÆ.--The principal subjective symptoms of mercurial stomatitis

are--characteristic fetor of the breath, sore gums and mouth,

continuous nauseous metallic brassy or coppery taste, and profuse

salivation.

At first the mouth feels parched and painful, the gums tender, the

teeth, the lower incisors especially, set on edge. Soon the gums become

swollen, and when touched with the tongue seem to have receded from the

necks of the teeth, which thereby appear to be longer than usual. The

gums feel quite sore when pressed upon with the finger or when put on

the stretch by clashing the rows of teeth against each other. This sort

of soreness is often watched for in the therapeutic administration of

mercurials purposely given to "touch the gums," as an indication that

the system is under the influence of the drug. It is, therefore, one of

the earliest indications of mercurial poisoning, but if not sought for

it may elude attention until after the mouth has become sore a little

later. The pain in the mouth is augmented by efforts of mastication and

expectoration, and may be associated with pains at the angle of the

lower jaw or extending along the domain of the third or of the third

and second divisions of the distribution of the fifth cerebral nerve.

Mastication of solid food is often unendurable. Constitutional

manifestations become evident about this time in increased heat of

skin, acceleration of pulse, furred tongue, dry mouth, great thirst,

and loss of appetite. The dryness of the mouth does not last long, but

is soon followed by hypersalivation, one of the characteristic

phenomena of the disorder. The saliva secreted, often acid in reaction,

varies greatly in quantity, which is usually proportionate to the

severity of the case. It is secreted night and day, sometimes to the

amount of several pints in the twenty-four hours--in moderately severe

cases to the amount of from one to two pints in that space of time. It

is limpid or grayish, mawkish or somewhat fetid, and reacts readily to

the simplest tests for mercury. The salivation is almost continuous,

sometimes quite so. The patient soon becomes unable to endure the

fatigue of constant expectoration, and the fluid then dribbles from his

mouth or runs off in an unimpeded slobber. When excessive, the

patient's strength becomes rapidly exhausted--in part by impoverishment

of the fluids, in great measure from the lack of refreshing sleep.

Meanwhile, the local inflammatory process extends from the gums to the

floor of the mouth and to the lips, and thence to the tongue and the

{346} cheeks. The salivary glands are in a state of inflammation

likewise, but rather in consequence of direct irritation in the

elimination of the poison through their channels than by extension of

the stomatitis along their ducts. The lymphatic glands of the lower jaw

become engorged and tender. Mastication, deglutition, and articulation

all become impeded mechanically by tumefaction of the tissues.

In some instances the glossitis is so great that the tongue protrudes,

thereby impeding respiration and even threatening suffocation. In some

cases oedema of the larynx has been noted, threatening suffocation from

that cause. Should the inflammatory process extend along the pharynx to

the Eustachian tubes, deafness and pains in the ears will become

additional symptoms.

The subsequent progress of unarrested mercurial stomatitis is that of

ulcerous stomatitis.

Should gangrene of the mucous membrane take place, there will be great

fetor from the mouth, and some danger of hemorrhage on detachment of

the sloughs should the process be taking place in the direction of

vessels of some calibre. Necrosis of the inferior maxilla entails

continuance of the disagreeable local symptoms until the discharge in

fragments or in mass of the dead portions of bone.

In the earlier stages of the attack the constitutional symptoms may be

sthenic. Fever, cephalalgia, and the usual concomitants of pyrexia,

however, soon give way to the opposite condition of asthenia. Exhausted

by the excessive salivation, and unable to repair waste by eating or

sleeping, the sufferer soon passes into a condition of hopeless

cachexia. Those who survive remain cachectic and feeble for a long

time--some of them disfigured for life by various cicatrices between

cheeks and jaw, by loss of teeth or of portions of the jaw-bone.

The duration of mercurial stomatitis varies with the susceptibility of

the patient, the intensity of the toxæmia, and the character of the

treatment. Mild cases may get well in a week or two; severe cases may

continue for weeks, and even months; extreme cases have persisted for

years. Even moderate cases occasionally resist treatment for weeks.

Under the improved therapeutics of the present day mercurial stomatitis

almost always terminates in recovery, especially if it receive early

and prompt attention. Neglected or improperly managed, it may terminate

in serious losses of tissue in gums, cheeks, teeth, and bone, leaving

the parts much deformed and the patient in a permanently enfeebled

condition.

Erysipelas, metastatic abscesses, inflammations, pyæmia, or

colliquative diarrhoea may be mentioned as complications which may

prove sufficiently serious to produce death, independently of the

virulence of the primary stomatitis.

PATHOLOGY AND MORBID ANATOMY.--Mercurial stomatitis is an ulcerative

process attended with an excessive flow of saliva containing mercury.

It has a tendency to terminate in destruction and exfoliation of the

mucous membrane of the gums and other tissues attacked, and eventually

in necrosis of the jaw-bone. The detritus is found, microscopically, to

consist of granular masses of broken-down tissue, swarming with

bacteria and micrococci, and containing some blood-cells and many

pus-cells. In some instances micrococci have been detected in the

blood.

The disease usually begins in the gums of the lower incisors, and {347}

extends backward, often being confined to one side of the jaw. The

gums, first swollen and then livid, become separated from the necks of

the teeth. Their edges undergo ulceration. The ulcers are surrounded by

fungous margins, pale or red, which bleed on the slightest contact, and

some become covered with grayish-yellow detritus. The ulceration

extends in depth, destroying the supports of the teeth, so that they

become loosened and even detached. The inflammatory process extends to

the lips, the cheek, and the tongue, which undergo tumefaction and

exhibit the impressions of the teeth in grayish opalescent lines or

festoons of thickened epithelium at the points of pressure. The

glossitis may become intense. It is almost always present, to some

extent, as a superficial or mucous glossitis. Occasionally acute

oedematous glossitis has ensued, and such cases sometimes terminate

fatally. Ulceration takes place in these structures similar to that

which has taken place in the gums. If not arrested, gangrenous

destruction ensues, not only in these tissues, but beneath them. Thus,

the teeth become loosened, and even detached; the jaw-bones themselves

may become bared, necrosed, and in part exfoliated; and the cheeks

undergo partial destruction by gangrene. Sometimes the inflammation

descends to the larynx, and this may produce oedematous infiltration of

the loose connective tissue of that structure. Sometimes it mounts the

pharynx and reaches the orifices of the Eustachian tubes. The salivary

glands become swollen and discharge great quantities of fluid, as

detailed under Symptomatology. The retro-maxillary and submaxillary

lymphatic glands become enlarged by inflammatory action.

DIAGNOSIS.--In the earliest stages the inflammation of the gums in

mercurial stomatitis cannot be distinguished from that which takes

place in other forms of ulcerative stomatitis. The fetor of the breath,

however, the profuse salivation, and the chemical reaction of the

saliva, together with the history of exposure to mercury, soon place

the nature of the case beyond doubt. Similar results following

poisonings by copper salts and by phosphorus are differentiated by the

history of the special exposure.
