title: [Rare malignant laryngeal tumors].
abstract: Six rare malignant tumors were found in a group of 136 laryngeal malignancies accessioned between 1990 and 1992. The other 130 neoplasms were squamous cell carcinomas. One case each of an adenocarcinoma, a mucoepidermoid carcinoma and an undifferentiated carcinoma of nasopharyngeal type were of epithelial origin; a case of a malignant fibrous histiocytoma, a chondrosarcoma and a plasmacytoma were of mesenchymal origin. The clinical presentations, histological findings, and therapy employed in the six cases are discussed and the available literature reviewed.
