Adenoid Cystic Carcinoma Presenting as a Tracheal Polyp

1. Abstract Tumours primarily involving the trachea are very rare, Adenoid Cystic Carcinoma accounts for most cases after Squamous Cell Carcinoma. Adenoid cystic carcinoma of the airway originates from the submucosal glands of the tracheobronchial tree. These tumours pose a diagnostic and therapeutic challenge because of their slow growth and tendency for local recurrence and late metastasis. We present a case of adenoid cystic carcinoma of the trachea masquerading as a tracheal polyp clinically.
