Endobronchial Leiomyoma: A case report with cryoprobe extraction and review of literature

Large airway tumors are uncommon, accounting for about 0.6% of all pulmonary tumors [[1], [2], [3]]. The majority of these tumors (80–90%) are malignant, represented primarily by squamous cell carcinoma and adenoid cystic carcinoma [2,4]. Benign central airway tumors are less common and are generally comprised of hamartomas and papillomas. Tracheobronchial leiomyomas are exceedingly rare, representing only about 0.6% of all benign lung neoplasms [3]. We report here on a case of primary endobronchial leiomyoma without uterine involvement treated successfully with cryoresection with excellent outcome.
