Bowenoid papulosis in three-year-old girl.

A three-year-old girl presented with perianal bowenoid papulosis that was presumed to be induced by sexual contact. The lesion was treated by biopsy only and regressed over 8 months without further therapy. The importance of this case with respect to the viral cause, venereal transmission, and spontaneous regression is discussed. This case represents the youngest known patient with bowenoid papulosis reported to date.
