Abstract
Pulmonary sclerosing pneumocytoma (PSP) arising from the hilar lesion is extremely rare. We report an asymptomatic 70-year-old female with a thoracic tumor of unknown origin. Contrast-enhanced chest tomography showed a poorly and heterogeneously enhanced 40-mm tumor compressing the left upper lobe, bronchus, and pulmonary arteries. Positron-emission tomography did not detect abnormal integration in the tumor. Surgical resection was planned to confirm diagnosis and avoid further compression on the structures. Intraoperative findings revealed a dark red-colored tumor, projecting from the left upper lobe in the hilar lesion. Left upper lobectomy was performed through video-assisted thoracoscopic surgery to achieve complete resection and avoid contact bleeding. Immunohistochemical examination revealed the presence of PSP.
