NEOPLASMS. TUMORS OF THE INTESTINE IN 

 SOUPEDS. 



L/ipoma : sessile or polypoid, pediculated, strangulatiou, stenosis, size. 

 Sarcoma : on bowel or peritoneum. Fibroma : flat or pediculated, obstruc- 

 tion, stenosis, degeneration, fatty, calcic. Myoma : hypertrophy of muscu- 

 lar coat, degeneration, stenosis. Myxoma : small translucent, oval, intes- 

 tine, mesentery. Carcinoma : extension from urocyst in horse, intestine, 

 lymph glands, spleen, stomach, liver, mesentery, omentum. Epithelioma : 

 colon, stomach. Cystoma : may contain sand or sclerostomata. Lympha- 

 denonia : rectum, colon. Undetermined neoplasms. Causes : foreign 

 bodies, microbes, constitutional, hereditary. Symptoms : tardy defecation, 

 obstruction ; in malignant, pallor, antemia, emaciation : peritonitis, ascites ; 

 foetid irregular stools, bloody, sloughs, rectal exploration. Treatment : 

 surgical removal where possible, recovery by sloughing, laparotomy, useless 

 in multiple or malignant tumors. 



Tttmors of the intestine are very varied in kintl (lipoma, sar- 

 coma, fibroma, myoma, myxoma, carcinoma, epithelioma, 

 cystoma), and are found on all portions of the canal. 



Lipoma ox fatty tufjior is most frequent in connection with the 

 small intestine or rectum, and on the mucosa it may assume a 

 pediculated or polypoid form and may more or less perfectly block 

 the intestine. When situated under the peritoneal surface it is 

 usually sessile and flattened apart from the mesentery, but if 

 growing from the latter or at its connection with the bowel it 

 tends to become pediculated, sometimes hanging at the end of a 

 very long cord which may roll around a loop of intestine and 

 .strangle it. Similarly the sessile mas.ses, as they increa.se press 

 inward so as to diminish the calibre of the bowel and finally clo.se 

 it. They are often found no larger than a coat button, while in 

 other cases they grow to enormous size (25 lbs. Vogt, 42 lbs. 

 Semmer). Semmer's case bound the caecum and colon to the 

 abdominal wall. The .structure is es.sentially fatty tissue, though 

 in .some cases the fibrous stroma is more dense than in others. 



Sarcoma. Small round cell tumors have been repeatedly found 

 in connection with the intestine or mesentery. Baranski found 

 one over 4 inches in length in the wall of the large intestine pro- 

 ducing a serious con.striction. Lucet found one of 18 lbs. weight 

 and Mouquet one of 7 lbs. attached to the omentum. They are
