Diagnostically Challenging Epithelioid Vascular Tumors

Abstract

The diagnosis of vascular tumors is a challenging area in soft tissue pathology. Epithelioid vascular tumors pose a particular challenge. Due to the epithelioid morphology of the tumor cells, they can be misdiagnosed as a variety of other entities, including metastatic carcinoma or epithelioid sarcoma. Furthermore, it can be difficult to distinguish between different epithelioid vascular tumors. This review focuses on vascular tumors characterized by epithelioid endothelial cells, including epithelioid hemangioma, cutaneous epithelioid angiomatous nodule, epithelioid hemangioendothelioma, epithelioid sarcomalike hemangioendothelioma/pseudomyogenic hemangioendothelioma, and epithelioid angiosarcoma.
