Abstract:
Carcinosarcoma is a biphasic tumor that has both epithelial as well as mesenchymal components. It most commonly occurs at the esophagus, lung, upper respiratory tract and urinary bladder, however it rarely occurs on the skin. A 62-year-old men presented with a bean sized crusted ulcer on his right cheek. A biopsy specimen revealed atypical sqamous cells mixed with spindle-shaped cells with hyperchromatic nuclei. Furthermore, immunohistochemical study showed positive reactions for AE1/AE3, cytokeratin7, epithelial membrane antigen and vimentin, but negative reactions for S100 protein, CD34 and smooth muscle actin. Based on these histopathological and immunohistochemical findings, we diagnosed this case as cutaneous carcinosarcoma. The patient was treated with complete excision and a local flap.
