Benign lung tumours are a heterogenous group of neoplastic lesions originating from pulmonary structures. These tumours include bronchial adenomas, hamartomas, and a group of uncommon neoplasms (e.g., chondromas, fibromas, lipomas, leiomyomas, hemangiomas, teratomas, pseudolymphomas, endometriosis). Although benign lung tumors do not pose a significant health problem, complications can result from an obstructive lesion that could predispose the patient to pneumonia, atelectasis, and hemoptysis. These tumours are considered benign, and, therefore, their malignant/cancerous potential is minimal. Benign tumours make up 2-5% of all primary lung tumours. The cause of benign lung tumours is not known.
