Leiomyoma of an accessory tracheal bronchus.

Abstract

We present a rare case of leiomyoma arising in an accessory right bronchus in a 55-year-old man who had been treated for bronchial asthma. Diagnosis was established on the results of bronchoscopic biopsy. An emergency operation was performed because the patient had begun to complain of severe dyspnea. The tumor was completely removed by electrocautery with a wire snare by rigid bronchoscopy. Postoperative bronchoscopic findings revealed a tracheal bronchus arising above the carina, and the root of the tumor existed in the orifice of the branch. Final histology revealed a leiomyoma.
