Herpes zoster (HZ) is a painful rash caused by the reactivation of the varicella-zoster virus (VZV) permanently latent within the cranial or dorsal root ganglia. Usually the rash presents in only one side of the body, in a single dermatome or restricted to a part of it. In immunocompromised patients, more than one contiguous unilateral dermatome, called multidermatomal HZ, has been described, usually in cervical dermatomes. Bilateral rash is rare. Besides immunosuppression, the major risk factors for virus reactivation are older age and female gender. This is a case of a bilateral lumbar multidermatomal HZ in an elderly woman with chronic renal failure.
