Carcinosarcoma and separate carcinoid tumor of the stomach. A case report with light and electron microscopic studies.
A carcinosarcoma of the cardia of stomach is reported. This is a rare entity which is of further interest because of an associated but distinctly separate carcinoid tumor. The main tumor showed distinct adenocarcinomatous and spindle cell components which collided in many areas. The sarcomatous nature of the spindle cell component was confirmed by ultrastructural studies. We have reviewed the literature and have not found a similar case.
