Abstract

Endobronchial leiomyoma is a rare tumor that accounts for less than 2% of pulmonary benign tumors. A 32 year-old woman was admitted with fever, cough and sputum for a month. She had suffered from intermittent cough over three years. The chest X-ray and chest CT(computed tomography) showed a nodular lesion obstructing the proximal portion of the left lower lobar bronchus and atelectasis of the left lower lobe. Flexible Bronchoscopy detected a mass obstructing the distal portion of the left main bronchus and endobronchial biopsy showed benign smooth muscle cells. There was no abnormal finding in the uterine examination. Therefore this case was diagnosed as primary endobronchial leiomyoma. The lobectomy was performed due to intractable pneumonia and secondary parenchymal destruction. Postoperative course was uneventful and she was discharged in good health.

Microscopy shows a submucosal leiomyoma composed of spindle-shaped smooth muscle cells (H&E, ×100), which are strongly positive to smooth muscle actin (Inset : ABC, ×400).
