When an infection goes untreated for a long period of time it may become as severe as the case pictured here. Genital warts commonly appear as painless, flesh-coloured or greyish-white growths in the genital area. They can be so small that they are only visible under a microscope, or they may gain a cauliflower-like appearance, which can be unsightly, itchy or mildly painful.
