Abstract
A tumor of the larynx composed of a small infiltrating and well-differentiated squamous cell carcinoma and a large polypoid sarcomatous mass showing the histologic features of the malignant giant cell tumor of soft parts (MGCT) is reported. Other types of sarcomatous components have been described with squamous cell carcinoma (SCC) of the larynx and names such as pseudosarcoma, carcinosarcoma, and spindle cell carcinoma have been used for these peculiar tumors. Because most data support that the sarcomatous component is an unusual carcinoma transformation due to unknown factors the authors prefer the term sarcomatoid carcinoma. Sarcomatoid carcinomas having the features of MGCT have been described in multiple epithelial organs. Therefore, an extensive search for a carcinoma component always should be carried out in tumors arising in any organ, including the larynx, and showing the typical histologic features of MGCT.Keywords
