[Primary endobronchial leiomyoma--endoscopic laser resection]

Abstract

Leiomyomas account for less than 2% of all benign lung tumors. Only one third is endobronchial in location, usually presenting as primary solitary lesions and airway obstruction findings. Literature on primary endobronchial leiomyomas is therefore scarce, with a few more than 100 cases being reported. We describe a case of a 44-year-old female that presented with bronchial asthma like symptoms and an obstructive pneumonia, due to a right main bronchus primary leiomyoma that was successfully resected using Nd:YAG laser through rigid bronchoscopy. Purpose of this case is to enhance the rarity of primary endobronchial leiomyoma diagnosis and report the relevance of laser resection in its definitive treatment. A brief review on lung leiomyomas is discussed over the text.
