In the gastrointestinal tract, carcinosarcomas are most frequently seen in the esophagus. Carcinosarcoma in the stomach is a rare tumor. We report a carcinosarcoma of the antrum of stomach. The tumor was polypoid and exophytic in appearance and located in the antrum. Immunohistochemical studies showed positivity for cytokeratin, epithelial membrane antigen and cytoplasmic carcinoembryonic antigen in the epithelial component. Positive staining with vimentin, desmin and focal smooth muscle actin and negative staining with chromogranin were observed in spindle cells. Nuclear positive staining was observed with p53 and Ki-67 in both glandular and spindle atypical cells. Pathology & Oncology Research, Vol 8, Nr 4, 275-277, 2002
