Pleomorphic Adenoma (Benign Mixed Tumor) of the Trachea

Abstract

A 15-year-old “asthmatic” found to have a pleomorphic adenoma of the trachea was treated by staged CO₂ laser excision Primary tracheal tumors, the clinicopathologic features of mixed tumor in this rare location, and therapeutic options are briefly reviewed Immunohistochemical stains for cytokeratin, S-100 protein, and glial fibrillary acidic protein are reliable methods of evaluating component cell types in pleomorphic adenoma, but immunohistochemical evidence has not resolved the issue of tumor histogenesis.
