Herpes zoster infection.

Caused by another herpes virus. Also known as shingles or chickenpox. Herpes zoster viruses may remain latent (inactive) for years (perhaps left over from childhood), but may be reactivated by HIV infection, causing inflammation of the spinal and cranial ganglia (nerve roots). In AIDS patients, can be disseminated (widespread) throughout the body. Often an initial clinical symptom in HIV-infected individuals. Herpes zoster is common among people not infected with HIV.
