[Pedicled polypoid carcinosarcoma: a very rare esophageal tumor].

Neoplasms of the esophagus normally appear either as a exophytic-polypoid form, or as an infiltrating carcinoma or as an ulcerating tumor. We report on a 86 year old man suffering from the rare case of a pedicle polypoid tumor of the esophagus histologically diagnosed as a carcinosarcoma. We discuss the histological problems and our diagnostic and therapeutic proceeding.
