Endobronchial leiomyoma: A rare and innocent tumour of the bronchial tree

An endobronchial leiomyoma is a rare tumor of the bronchial tree. Very few cases have been reported in literature. 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. These tumors arise from the smooth muscle of the bronchial tree. Symptomatology is based on the degree of endoluminal bronchial obstruction and surgical resection has generally been the mainstay of treatment. We describe a case of endobronchial leiomyoma in a 42 year old female. A diagnosis of Primary endobronchial leiomyoma was made on the basis of histopathology and immunohistochemistry. Rarity of this tumor in the bronchial tree with coexisting interstitial peumonitis urges us to report this case.
