External genital warts (condylomata acuminata) are a common STI caused by the human papillomavirus (HPV) subtypes 6, 11, 16, and 18. Genital warts can be found on the mouth, anus, penis, vagina, vulva, and cervix. They are itchy, can be raised or flat, and may develop as a single wart or form a cluster resembling cauliflower. The United States diagnoses 500,000 to one million new cases each year. On average, physical symptoms begin approximately 2 to 3 months after initial contact. Below are pictures of genital warts on dark skin.
