Abstract

A 70-year-old man was admitted to our hospital for an abnormal shadow on chest X-ray film. Chest CT scan showed a mass shadow sized 1.5×1.2 cm at the periphery of the left S1+2. Bronchoscopic examination revealed a yellowish white pulpwood tumor which protruded from the orifice of the left upper segment bronchus. However, because no definitive histological diagnosis was obtained preoperatively, left upper lobectomy was performed. On histological examination, the tumor covered by normal bronchial epithelium was composed of adipose tissue, cartilage and fibrous tissue, which was considered endobronchial hamartoma. The peripheral lung tumor at S1+2 was diagnosed as moderately differentiated adenocarcinoma.
This is the third reported case of endobronchial hamartoma associated with lung cancer.
