Hemangioendothelial sarcoma of penis

Abstract
Hemangioendothelial sarcoma of the penis in a 44-year-old man was treated by preoperative radiation, penectomy, and chemotherapy. The patient was free of evident disease 2 years later. Electronmicroscopy showed differentiated vascular structures at the periphery of the lesion and anaplastic cells throughout the remainder of the tumor.
