Pulmonary sclerosing hemangioma, also known as pneumocytoma, is a rare benign neoplasm. The cellular origin of this neoplasm is not clear. We report a 65 years old man with a sclerosing hemangioma excised from right lung. Since pneumocytoma, is a rare benign neoplasm having an indistinct origin, we discussed the pathological and immunhistochemical findings of our case.
