NEOPLASMS. TUMORS OF THE INTESTINE IN 

 SOLIPEDS. 



Lipoma : 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- 

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

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

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

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

 surgical removal where possible, recovery by sloughing, 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 inte.stine or rectum, and on the mucosa it ma}' assume a 

 pediculated or polypoid form and may more or le.ss perfectly block 

 the intestine. When situated under the peritoneal surface it is 

 usually sessile and flattened apart from the me.sentery, 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 inte.stine and 

 strangle it. Similarly the .se.ssile ma.sses, as they increase 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 essentially fatty ti,ssue, 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 inte.stine 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 Mouquet one of 7 lbs. attached to the omentum. They are
