A Case of Epithelioid Hemangiosarcoma with Multiple Metastatic Deposits on the Skin, Subcutaneous Tissue, Muscles and Bones Localized in a Limited Area of the Left Pelvic Region: A Possible Metastatic Route via the Vertebral Vein System

Abstract

A 79-year-old man was found to have epithelioid hemangiosarcoma of the bladder and multiple metastatic deposits on the skin, subcutaneous tissue, muscles, and bones localized in a limited area of the left pelvic region. He had also a metastatic nodule on the glans penis. No pulmonary or liver metastases were noted. It is suggested that the peculiar distribution of his metastatic lesions could be explained by a route via the vertebral vein system of Batson but not by orthodox hematological or lymphatic spread.
