Condylomata acuminata are caused by up to 60 different strains of the human papillomavirus (HPV). HPV 6 and 11 are typically associated with benign disease whereas HPV 16 and occasionally HPV 18 are more likely to lead to invasive squamous cell carcinoma. Evidence from several sources suggests that the presence of vulvar condylomata acuminata predisposes to the development of carcinoma at that site The two lesions are often found in the same patient; from 7% to 26% of women with vulvar squamous tumours are found to have one or more condylomata.
