Carcinosarcoma of the stomach is a rarely occurring malignant biphasic tumor that consists of both carcinomatous and sarcomatous components simultaneously in a single tumor.
The common carcinoma component is tubular or papillary adenocarcinoma and the mesenchymal sarcomatous components are variable and these include leiomyosarcoma, rhabdomyosarcoma, osteosarcoma and chondrosarcoma. However, neuroendocrine carcinomatous differentiation in the carcinomatous component is extremely rare. We present here a rare gastric carcinosarcoma that demonstrated neuroendocrine carcinomatous and leiomyosarcomatous differentiation in a 47-year-old man.
