Vegas (Verruciform Genital-Associated) Xanthoma: A Comprehensive Literature Review

INTRODUCTION Verruciform xanthoma is a wart-like benign lesion. The classic histologic appearance consists of foamy histiocytes within elongated dermal papillae and epithelial acanthosis. The lesion most commonly occurs in the oral cavity, but has been reported in extra-oral sites such as the penis, scrotum, and vulva. The clinical and histologic characteristics of verruciform genital-associated (Vegas) xanthomas of the penis, scrotum, and vulva are reviewed. METHODS PubMed was used to search the following term: verruciform xanthoma. The relevant papers were obtained and reviewed. RESULTS There have been 193 cases of genital-associated verruciform xanthomas. There were 164 in men and 29 in women. Similar to verruciform xanthomas of the oral mucosa, they presented as asymptomatic lesions, demonstrated foam cells in the dermal papillae, and were typically managed successfully with surgical excision. CONCLUSION Verruciform xanthoma is a benign lesion characterized by a wart-like growth that is most commonly seen in the oral mucosa. Verruciform xanthomas of the genital region have been coined Vegas xanthomas. Vegas xanthomas have been reported in association with a variety of diseases, as well as in healthy individuals. Biopsy is required for diagnosis, and complete surgical excision is typically curative.
