Mucinous adenocarcinoma of trachea: a rare case of primary tracheal tumor.

A primary tracheal tumor is not common, but adenocarcinoma is particularly rare. We describe a case of primary tracheal mucinous adenocarcinoma misdiagnosed as asthma in a 17-year-old girl. Computed tomography revealed an intraluminal partially obstructing mass in the mid portion of the trachea. A sleeve resection of the involved trachea with primary anastomosis was performed, followed by adjuvant radiotherapy. After 23 months of follow-up, there has been no recurrence.
