A Case of Tracheal Leiomyoma / 대한내과학회지

ABSTRACT

Leiomyomas account for 2% of the benign tumors of the lower tracheobronchial tree. Tracheal leiomyomas most commonly occur in the fourth decade man. The most co mmon segment to be affected is the lower third of the trachea and the usual site of origin is the posterior mem branous portion. Symptoms are due to partial or com plete obstruction of the trachea. Intermittent or constant dyspnea and wheezing are the most common symptoms of tracheal leiomyoma and have been erroneously ascri bed to bronchial asthma. Clinical symptoms distinguished from bronchial asthma, chest CT scan and bronchoscopy can make diagnosis. The diagnosis of leiomyoma of the lower respiratory tract is by chest C-T scan and bronc hoscopy, which gives direct visualization and biopsy ma terial is sent for histologic examination. The treatment of leiomyoma is essentially conservative since there have been no reports of recurrence after limited resection. Intr atracheal leiomyomas have been dealt with in three ways by bronchoscopic removal, by excision via a tra cheotomy, and by circumferential resection with primary end-to-end anastomosis. In recent years, successful mass removal with YAG laser and electrocautery technique were reported. We have experienced 36 year-old-male with hemopty sis, cough and sputum production. Tracheal leiomyoma was diagnosed by chest CT scan and bronchoscopy. Mass removal and tracheoplasty were done successfully. So we present this case with the review of literature.
