Sarcomtoid carnoma of the small intense: A case report and review of the literature

Sarcomatoid carcinomas are rare biphasic tumors composed of mixed malignant epithelial and mesenchymal cells. A few cases for small intestinal sarcomatoid carcinoma were reported. Moreover, most of the cases are focused on the pathologic review. We experienced a case of monophasic sarcomatoid carcinoma arising in the jejunum in a 78-year-old man. In this case, CT showed fungating mass with central necrosis in the jejunum. We also reviewed literatures on sarcomatoid carcinoma that arises in the small intestine.
