Pulmonary Hamartoma: Curative Laser Resection
Pulmonary hamartoma usually presents as a single lesion in the periphery of the lung. It occurs in 0.3% of general population, with a higher frequency in male gender and in the sixth decade of life. Endobronchial hamartomas are unusual. This image corresponds to a 81 year-old man with history of coronary artery disease, hypertension, and rheumatoid arthritis who was admitted to the hospital with chest pain and shortness of breath. Cardiac catheterization revealed multi-vessel disease. He underwent coronary artery bypass therapy (CABG). Post CABG, his clinical course was complicated by right upper lobe and left lower lobe atelectasis. Bedside bronchoscopy revealed a right upper lobe entrance mucus plug and a left lower bronchus endobronchial lesion (Fig. 1, Panel A). Biopsy of the lesion was consistent with an endobronchial hamartoma. The patient underwent complete resection of endobronchial hamartoma using argon laser (Fig. 1, Panel B), with significant clinical improvement.
