[ Causes of colon sarcoma
Sarcomas can arise from all tissues of the intestinal wall, except for the epithelial. Histological examination most often reveals fibrosarcomas, myxosarcoma, angiosarcomas; melanomas are sometimes detected in the rectum.
Symptoms of Colon Sarcoma
Clinical manifestations of colon sarcomas are generally similar to those of colorectal cancer. However, the course of this disease is usually faster. Colon sarcomas are less likely to cause intestinal bleeding and intestinal obstruction. Sometimes sarcomas reach a significant size and can be palpated through the abdominal wall.
Diagnosis of colon sarcoma
A digital examination is of great importance for detecting a rectal tumor. Tumors located more proximally are easily detected by irrigoscopy and colonoscopy (with biopsy). Sometimes, to confirm the diagnosis of sarcoma (in particularly difficult to diagnose cases), a CT scan is performed. ESR is usually increased, and anemia is noted.

Prognosis for colon sarcoma
The prognosis (without surgery) is unfavorable; with surgical treatment, tumor relapses often occur soon. Sometimes colon sarcomas respond to radiation therapy with temporary or longer (several years) remission.
