림프절 전이를 동반한 폐세포종(경화성 혈관종) - 1례 보고 -

Abstract

A case of pneumocytoma(so-called sclerosing hemangioma) with regional Iymph node metastasis is reported. A round lesion in the right hilar region was incidentally found in a 29-year-old man. He underwent right upper lobectomy and Iymph nodes dissection with preoperative impression of bronchogenic adenocarcinoma. The tumor was well circumscribed with characteristic histological feature of sclerosing hemangioma. Several Iymph nodes contained metastatic deposits of proliferating pale cells with formation of glandular spaces. A Ithough pneu ocytoma is said to be benign, quite rare cases apparently show metastatic potential.
