A case of huge esophageal carcinosarcoma.

Carcinosarcoma of the esophagus is a rare malignant neoplasm with both epithelial and mesenchymal (sarcomatous) components. We describe a case of a 72-year-old man with a huge esophageal tumor which could often have been considered inoperable. However, the patient underwent a curative resection and had a good prognosis. In this report, we suggest that carcinosarcomas have a lower tendency of invasion, even late in their course. We therefore recommend aggressive surgical resection of this kind of tumor.
