Background: Endobronchial lipomatous hamartoma is a rare benign tumor of the tracheobronchial tree.Differentiation between endobronchial lipomatous hamartomas and endobronchial lipomas
has not been made in the literature. The majority these were endobronchial lipomatous hamartoma while there were only a few cases of endobronchial true lipomas.Case Report: We present a rare case report with an endobronchial lipomatous hamartoma which occluded the left lower lobe bronchus. The need to be more precise is illustrated by this case report. A well circumscribed and obstructed the bronchus of the left lower lobe was seen by fiberoptic bronchoscope. The left lower lobe was resected as the tumour may causing bronchiectasi and atelectasi. Pathological examination revealed diagnosis of endobronchial lipomatous hamartoma. A repeat bronchoscopy was performed revealing normal findings without any recurrent lesion.Conclusions: Benign endobronchial tumors are rare and there is considerable confusion regarding the nomenclature and classification. Early endoscopic examination is important for the detection of these tumors before the lung distal to the obstruction is irreversibly damaged. Due to their benign nature, endobronchial lipomas-hamartomas should initially be treated endoscopically or surgically.
