Pulmonary sclerosing hemangioma with metastasis to the mediastinal lymph node.

Abstract

During a routine health care evaluation, an abnormal shadow was detected in the chest roentgenogram of a 35-year-old man. Chest computed tomography scanning showed a nodule, approximately 3 cm in diameter, in the left S6 pulmonary segment with surrounding infiltration. Bronchoscopy revealed obstruction of the left B6c bronchus by a tumor, for which biopsy was done but no definitive histologic diagnosis could be made. Then, left lower lobectomy was performed, and the tumor was diagnosed as a pulmonary sclerosing hemangioma. A mediastinal lymph node (no. 7) showed some metastatic tumor cells. As lymph node metastasis from pulmonary sclerosing hemangioma is very rare, we herein report the details of our case.
