[Verruciform xanthoma of the penis].

Verruciform xanthoma (VX) usually occurs within the oral cavity, rarely in the genital areas. A case of VX on uncircumcised penis is reported in a 58 year-old man without prior history of sexual transmitted disease; histological features are characteristic and staining of the foam cells are positive with CD68 and negative with S100 protein. Etiological factors of the VX are uncertain and in the genital localizations a viral cause has not been proved.
