  • Title: [Vascular eccrine giant spiradenoma--a case report with histology and immunohistology of a rare variant of benign sweat gland tumors].
    Author: Hey A, Grouls V, Röckelein G.
    Journal: Z Hautkr; 1988 May 15; 63(5):444-7. PubMed ID: 2841813.
    Abstract:
    Giant vascular eccrine spiradenoma (GVES) is a rare variant of benign tumors of the sweat glands, which differs from common eccrine spiradenoma in both its size and vascularity. Clinically as well as macroscopically, this intradermal or subcutaneous encapsulated tumor might be mistaken for an angiomatous lesion or thrombosis. Histological examination reveals clearly delimited "cords" showing two types of cells, prominent blood-filled cavities and extensive hemorrhages. According to immunohistochemical findings, the epithelial cells contain cytokeratin, protein S-100 and carcino-embryonal antigen (CEA). Like the endothelial cells of vessels, some of the luminal epithelial cells also bind Ulex europaeus lectin; however, they do not show factor VIII-associated antigen.
