NEOPLASMS. TUMORS OF THE INTESTINE IN 

 SOEIPEDS. 



Lipoma : sessile or polypoid, pediculated, strangulation, 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. Lympba- 

 denoma : rectum, colon. Undetermined neoplasms. Causes : foreign bod- 

 ies, microbes, constitutional, hereditary. Symptoms : tardy defecation, ob- 

 struction ; in malignant, pallor, anaemia, emaciation ; peritonitis, ascites ; 

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

 gical removal where possible, recovery by sloughiug, laparotomy, useless in 

 multiple or malignant tumors. 



Tumors of the intestine are very varied in kind (lipoma, sar- 

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

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



Lipoma or fatty tumor 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 masses, as they increase press 

 inward so as to diminish the calibre of the bowel and finally close 

 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 essentially 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 constriction. Lucet found one of 18 lbs. weight 

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