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.
