Perineal muco-cutaneous herpes zoster treated with brivudin.

Herpes zoster results from the reactivation of latent varicella-zoster virus (VZV) from the dorsal root ganglion of sensory nerves. It is rarely described in the pediatric population. We report the case of an 8-year-old immunocompetent boy with a painful lumbosacral herpes zoster that was treated with brivudin and achieved rapid and sustained improvement in the absence of muco-cutaneous or pharmacological side effects.
