Pleomorphic adenoma (benign mixed tumor) of the trachea.
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.
