A Rare Case of Giant Pulmonary Hamartoma

Abstract

Yuanyuan Zong and Xichao Sun

We report a case of huge pulmonary hamartoma with atrophied right lower lobe in a 33-year-old female patient. The pulmonary hamartoma was solid, 30 × 16.5 × 14.5 cm in size, which sectioned surface reveals a thick-walled fibrous cyst with multiple yellow nodules protruding into the lumen. The tumour was compressing the right lung and there was no evidence of infiltration into the surrounding structures. It was successfully treated by surgical resection and final histology was pulmonary hamartoma with predominantly fibrous tissue, cartilaginous tissue and leiomyomatous differentiation. We believe this is the largest reported case in literatures yet, and this was successfully resected via a median sternotomy.
