Verruciform xanthoma of the glans penis: a benign clinical simulant of genital malignancy.

Verruciform xanthoma is a benign disorder affecting skin and mucosa. Although most cases have been reported to occur in the mouth, other sites may be affected, most notably the genitalia. A large, exophytic verruciform xanthoma involving the glans penis is reported. The clinical similarity to a malignancy, especially verrucous carcinoma, is emphasized. The differential diagnosis and histologic features are reviewed along with a summary of the literature regarding this uncommon condition.
