Sarcoma: usually near lymph glands. Lipoma: mucosa, serosa,
pediculated, strangulation, obstruction. Fibroma: floating colon.
Carcinoma: generalized cancer, colon. Cystoma; reticulum, omasum,
abomasum. Undetermined tumors. Symptoms: discovery by rectal
examination, in case of debility or digestive disturbance. Treatment:
removal through rectum or by laparotomy, spontaneous sloughing.
Hyperplasia of intestinal mucosa.
=Sarcoma.= Multiple sarcomata have been found in nearly all parts of the
abdominal cavity but above all in or near the lymph glands. They are
from a small size up to masses of 60 lbs. (Revel).
=Lipoma.= Fatty tumors are found attached to the mucosa, and peritoneum,
but above all as masses with long elastic pedicles which are liable to
wind round and obstruct the intestines. Tannehauer records a case of
fatal obstruction of the small intestine from a lipoma of the mucosa,
and Pritchard two cases of fatal obstruction of the rectum by a fatty
neoplasm occupying its walls.
=Fibroma.= Furianetto furnishes an interesting case of a fibrous tumor
connected with the mucosa of the floating colon, on which it had dragged
so as to cause a fatal invagination.
=Carcinoma.= Mauri relates a case of multiple cancer involving not only
the intestines but also the lymph glands, the heart, the brain, the
muscles, etc. Landis also records the case of a cancerous tumor of six
inches in circumference attached to the floating colon of a calf.
=Cystoma.= Tumors of this kind have not been found to any extent in the
intestines of cattle. Reboul describes a large cyst weighing 20 lbs.,
attached to the reticulum, omasum and abomasum and containing a
pultaceous fœtid debris. There was attendant congestion of the colon.
=Tumors of Uncertain Kind= have been recorded by other observers.
_Symptoms._ As in the soliped the one diagnostic symptom is the
discovery of the neoplasm and its effects by rectal examination, in
those cases in which the tumor is within reach. Apart from this there
are the general symptoms of ill health, anæmia, pallor of the mucosa and
emaciation in malignant cases, and recurrent colics, tympanies, impaired
rumination and appetite, with dark colored liquid or bloody fæces, or
complete suspension of defecation. In Pritchard’s cases one animal was
in the highest possible condition, having been in preparation for the
Smithfield (London) fat stock show.
_Treatment._ If the tumor has been diagnosed with certainty, it may be
removed by surgical means from its seat in the rectum, or even from
other parts if not multiple or malignant. Laparotomy is better borne in
cattle than in horses.
=Hyperplasia on the Intestinal Mucosa in Cattle.= In a Jersey heifer
presented at the clinic of the New York State Veterinary College a
hyperplasia of the mucosa of the duodenum, which blocked the lumen, was
removed and the bowel resected. On examination the mass was found to be
the result of productive inflammation, and undergoing necrosis and
separation.
