Abstract
Primary tracheal tumors are rare. Adenoid cystic carcinoma of trachea is even rarer. It occurs as a polypoidal mass in trachea presenting with dyspnea and respiratory distress due to tracheobronchial obstruction. We report a case of young male presenting with dyspnea for some time. CT scan revealed mass in trachea obliterating its lumen. Histopathological examination conirmed the diagnosis.
Highlights
Adenoid cystic carcinoma is a rare tumor of salivary gland origin, found mostly in head and neck region but has been reported in breast, lacrimal gland of eye, lung, bartholin’s gland, trachea and parasanal sinuses.[1,2] Primary tracheal tumors are rare and constitute only two 2% of all respiratory tract tumors.[1]
We report a case of young male presenting with polypoidal tracheal mass with complains of dyspnea and respiratory distress as initial clinical presentation
A 31 year-old male presented with respiratory distress for 3 months
Summary
A 31 year-old male presented with respiratory distress for 3 months. All the base line blood investigations were within normal limits. Bronchoscopy showed an intramucosal 2x2cm mass at mid trachea approximately 5 cm distal to vocal cord and 6 cm proximal to carina. CT scan revealed well deined heterogeneously enhancing broad based polypoidal soft tissue mass of 20x19x14.5 mm from posterior wall of trachea obliterating its lumen. Operative indings revealed polypoidal mass measuring 2x2 cm attached to trachea over mid trachea with intact adventitia. Mass was obliterating around 80%of tracheal lumen. Tracheal tissue with an intraluminal mass attached to tracheal ring. Lesion revealed basaloid cells arranged in iniltrating cords, cribriform pattern along with some tubules.(ig.3) Tumor cells show moderate degree of atypia.
