Lesions begin as small bumps and may be grouped together. The lesions often have a centrally depressed center with a white core and a mildly reddened base.
Lesions are frequently in the groin, on the buttocks, along the inner thigh and in the pubic area.
The lesions appear two to seven weeks after exposure. Lesions may become red and sore when body tries to reject the virus. This symptom is harmless and can be ignored. Diagnosis A diagnosis is made by a medical provider identifying the distinctive clinical appearance of the lesions, by a lab smear of the core or by biopsy. Since the condition may go away on its own and the lesions usually heal without scarring, treatment is not mandatory but is very desirable because it is contagious.
