title: [Sarcomatoid carcinoma of the colon: report of a case and review of the literature].
abstract: Sarcomatoid carcinomas or carcinosarcoma are rare tumors composed of mixed carcinoma cells and mesenchymal cells. Thirteen cases with colorectal involvement have been published to date. We report a case of sarcomatoid carcinoma of the colon in a 67-Year-old woman hospitalized with a history of anemia and bloody stools. The patient underwent a left hemicolectomy. Immunohistochemistry revealed two cell components (undifferentiated carcinomatous and sarcomatous components). The patient died of her tumor 2 Months after the operation. Our review of the literature stresses the poor prognosis associated with colonic sarcomatoid carcinoma.
