Two Cases of Bronchial Leiomyoma Initially Misdiagnosed as Bronchial Asthma

Leiomyoma of the bronchus is a very rare benign tumor of the lung. Leiomyoma is usually found in the young and the middle age. The symptom depends on the location of the tumor, it's size, and changes in the lung distal to the lesion. Obstructive symptoms due to leiomyoma could be similar to those of asthma and bronchitis, and therefore delayed diagnosis is common. The treatment of leiomyoma is conservative since there have been no reports of recurrence after limited resection. Recently bronchoscopic tumor resection has been applied to selected cases. We experienced two cases of bronchial leiomyoma initially misdiagnosed as bronchial asthma which were successfully excised by resection, end-to-end anastomosis and bronchoplasty. To prevent destructive changes of lung distal to obstruction and to preserve the pulmonary function, early diagnosis and appropriate treatment are important points of consideration.

기관지 천식으로 오인된 기관지 평활근종 2예

호흡곤란, 기침, 천명 등의 증상으로 기관지 천식을 진단 받고 이에 대한 치료를 받던 중증상 호전이 없어 시행한 흉부전산화단층촬영 및 굴곡성 기관지내시경 검사상 진단되어 기관지절개술 및 기관지성형술로 재발과 잔여 종괴 없이 치료된 기관지 평활근종 2예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
