Abstract

This report describes an epithelioid hemangioendothelioma arising on the spermatic cord of a 50-year-old man who presented with a nodule in the right hemiscrotum. Histologic examination showed a cellular tumor composed of epithelioid cells, many of which had intracytoplasmic lumina containing red blood cells. Immunohistochemistry showed focal positivity of tumor cells with the endothelial markers CD34, factor VIII-related antigen, and Ulex and with the anticytokeratin antibodies CAM5.2 and AE1/AE3. Ultrastructural examination revealed polygonal tumor cells forming vascular spaces and intracytoplasmic lumina containing red blood cells. This is the second documented occurrence of epithelioid hemangioendothelioma at this site. The case illustrates the value of immunohistochemistry and electron microscopy in establishing a diagnosis.
