Endobronchial Hamartoma as a Rare Cause of Recurrent Respiratory Symptoms: Case Report and Literature Review

Abstract

Most of the endobronchial lesions are malignant in origin. In rare instances, benign lesions occupying the endobronchial tree can mimic malignant neoplasms on conventional imaging tests. We present a case of a middle-aged male patient who was admitted to our hospital with recurrent hemoptysis concerning for lung cancer on computed tomography (CT) of the chest. Biopsy of the mass obtained via bronchoscopy revealed a benign lesion most consistent with lipomatous hamartoma, which is known to constitute only 10% of all pulmonary hamartomas. We also present the data of a comprehensive literature review of the epidemiology, clinical symptoms, diagnosis, treatment, and prognosis of patients with endobronchial hamartomas.
