It is indicated with a history of warts or HPV, sexual contact with a partner with warts or HPV, high-risk sexual behavior, or STD. Using a 10x power magnifying lens, gauze, and a 5% acetic acid solution, wrap the penis and the scrotal area with gauze wrap that has been impregnated with the 5% acetic acid solution for 5 minutes. Topical stain, sterile normal saline, and 70% isopropyl alcohol will not "whiten" the lesions.
