Pleomorphic Adenoma of the Trachea: A Case Report

1998 
: Pleomorphic adenoma is the most common form of major salivary gland tumors,but it is exceedingly rare in the trachea. We present a case of pleomorphic adenoma of the trachea in an 80-years-old man. Chest three-dimensional CT demonstrated a bosselated mass with a lobulated surface arising from the membranous portion of the upper trachea. Transbronchoscopic biopsy from the mass showed a biphasic histologic appearance produced by a mixture of glandular structure and hyaline-like stroma. The pathological diagnosis was pleomorphic adenoma.
