Resection of the entire left mainstem bronchus for an inflammatory pseudotumor.

We present the case of a 16-year-old white girl with a history of recurrent postobstructive pneumonia. Chest roentgenogram, chest computed tomography, and bronchoscopy revealed a mass in the left mainstem bronchus with an exophytic component. Multiple bronchoscopic biopsies confirmed the mass to be an inflammatory pseudotumor. After failing months of medical therapy with systemic steroids as well as several laser ablations, the tumor was removed through a left thoracotomy with resection of the entire left mainstem bronchus and reimplantation of the left upper and lower lobe into the trachea without complication or recurrence after 1 year.
