Abstract

A case of pneumocytoma(so-called sclerosing hemangioma) with regional lymph 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 lymph nodes dissection with preoperative impression of bronchogenic adenocarcinoma. The tumor was well circumscribed with characteristic histological feature of sclerosing hemangioma. Several lymph nodes contained metastatic deposits of proliferating pale cells with formation of grandular spaces. A lthough pneumocytoma is said to be benign, quite rare cases apparently show meta- static potential.
