Multiple Sclerosing Hemangiomas of the Lung with Lymph Node Metastasis-A Case Report

Sclerosing hemangioma of the lung is an uncommon benign tumor of uncertain histogenesis. It is usually solitary and clinically benign with no instances of recurrence after excision. We report the case of a 40-year-old man with multiple sclerosing hemangiomas in the left lower lung accompanied by lymph node metastasis. These features suggested a very low-grade malignancy with metastatic potential. Tumor cells from the lungs and lymph node were focally immunoreactive for progesterone receptors, of which the clinical significance remains to be solved. The patient's postoperative course was good, and there was no evidence of recurrence 20 months after surgery.
