Condylomata acuminata are benign epitheliomas which are caused by the human papilloma virus. 8 subgroups (variants) of the virus are known up to now. Condylomata acuminata are infectious, the virus being transferred by direct contact with a lesion. Condylomata acuminata are found more often in males than in females and never occur in children prior to the age of two years. The peak incidence is between 19 and 22 years of age. Greatly proliferating condylomata acuminata (type Buschke-Löwenstein) may lead to malignant degeneration. There exists a broad spectrum of topical therapeutic modalities: cytotoxic substances such as podophyllin (10 to 25%), colchicine (8%), 5-fluorouracil (1 to 5%), cryotherapy (solid carbon dioxyde or liquid nitrogen), surgical treatment (excochleation, electrocautery or laser beam. Vaccination therapy may prove successful in certain cases in the future.

A case of squamous cell carcinoma developing in a perianal condyloma acuminatum in a 38-year-old man treated for over 5 years with podophyllin is presented. Although there are many reports of malignant transformation of condyloma acuminatum in the skin and mucosal surfaces of the male and female genitalia, it is quite rare in the perianal region. In this case there were foci of carcinoma in-situ and of frank invasion, as well as areas of squamous cell carcinoma in the large perianal condyloma. The lesion was widely excised, and completely removed, and the site covered with a split-thickness graft from the thigh. Later, repeated dilatations of the anus were required. Repeated histologic examinations of condyloma acuminatum are needed to diagnose possible malignant transformation.
