Genital warts generally do not become clinically apparent until several months after inoculation with HPV. They follow a slow and indolent course and may develop by inoculation from opposing surfaces.
Flat condylomata (squamous intraepithelial neoplasia) are the most common lesions of the cervix but may also develop on the vulva, anus, and male genitalia. They appear as white plaquelike growths.
Palmoplantar warts appear on the acral surfaces of the feet and hands. They are notable for their thickness, which complicates treatment. Deep plantar warts occur most commonly as solitary lesions that may become black and painful before spontaneously regressing. They may contain small black "seeds," which are thrombosed capillaries.
EV generally begins in childhood and can affect almost any area of the body. The warts are generally subtle and flat and may initially be mistaken for tinea versicolor. EV tumors are locally destructive. They develop slowly and have weak metastatic potential if no cocarcinogens, such as x-ray or ultraviolet B irradiation, are applied. Polymorphic, plane wart-like, and red-to-brownish plaques can be distributed widely over the skin. The lymph nodes and oral mucosa are not involved.
