Genital Herpes Zoster: A Rare Location That Can Mimic Genital Herpes.

Herpes zoster is an acute, cutaneous viral infection caused by the reactivation of varicella-zoster virus. Genital dermatomes are involved in only up to 2% of cases and are probably underrecognized. We present a series of 7 genital herpes zoster cases diagnosed in our Unit of Sexually Transmitted Diseases. None of our patients were positive for HIV test, and only one was taking immunosuppressive medication. We recommend the use of molecular testings to confirm the diagnosis of varicella-zoster virus or herpes simplex virus infection in all cases of genital herpes-like lesions.
