Carcinoma of the oesophagus with spindle cell features

Abstract
There is considerable confusion surrounding the histogenesis and nomenclature of squamous cell carcinomas of the oesophagus with spindle cell elements. These tumours, many of which are polypoid, have been variously called carcinosarcoma, pseudosarcoma and polypoid carcinoma of the oesophagus. A study of three recent cases strongly supports the theory that these tumours are squamous cell carcinomas with spindle cell metaplasia. They are not necessarily polypoid and adenocarcinomatous elements may also be present.
