This is the same type of virus that causes warts on the hands and feet. They are usually spread to the vulva through sexual contact but can in some instances be spread by other means. The growths are occasionally seen before puberty or after menopause.
Lesions can also arise on the skin near the anus, vagina, cervix and urethra.
They usually appear first as a small thickened area of skin with definite edges. Occasionally, they spread and enlarge, forming a large cluster of warts that look like tiny cauliflower. The warts appear on the vulva as raised and sometimes reddened patches that may hurt or itch. Treatments occur weekly until the warts are gone. Burning may temporarily follow its application.
