Carcinosarcoma of the esophagus: report of two cases

Carcinosarcomas are malignant tumors containing both epidermal and mesodermal components. They are rare in the esophagus, but when present frequently have a characteristic radiographic appearance presenting as a bulky, intraluminal, polypoid filling defect. Although capable of metastatic spread, their usual indolent nature offers a relatively favorable prognosis.
