Endobronchial Leiomyoma: A Case Report / 대한흉부외과학회지

ABSTRACT

Endobronchial leiomyoma is extremely rare and accounts for less than 2% of benign tumors of the lower respiratory tract. Leiomyomas are predominantly found in the young and the middle aged of the average age being 35 years for bronchial and lung parenchymal lesions and 40.6 years for tracheal lesions. The symptom depends on the location of the tumor, its size, and changes in the lung distal to the lesion. A 37-year-old woman was admitted to our hospital complaining of coughing. Bronchoscopy revealed complete obstruction of the right main bonchus at the carina by an oval-shaped, nonulcerative, smooth, and pinkish-tan tumor with a broad margin and extended to the left main bronchus. A biopsy was performed and showed a benign spindle cell tumor. A right pneumonectomy was performed because of chronic infection, and the lung could not expanded during aeration. The histological diagnosis of the resected specimen was leiomyoma. The postoperative course was uneventful.
