Extragenital condyloma acuminatum in the left axillary vault

Condyloma acuminatum is a benign epithelial proliferation attributed to the epidermotropic human papillomavirus (HPV) and generally associated with sexual transmission. More than 100 types of HPV have been discovered, but strains 6 and 11 are found to cause approximately 90% of condyloma acuminatum. Lesions occur most frequently on the mucous membranes of the anogenital region, but also may occur in the conjunctiva and oral mucosa. Extragenital condyloma acuminatum not associated with sexual activity is rare, having previously only been described in the groin and inframammary fold.
