Herpes zoster.

Herpes zoster (HZ) or 'shingles' is a painful vesicular rash resulting from reactivation of the varicella-zoster virus that also causes chickenpox. The incidence of HZ infection (HZI) increases with age and the degree of immunosuppresssion. Post herpetic neuralgia, the most common complication of HZ, occurs after the zoster rash has resolved. Conventional therapies include antivirals, corticosteroids and analgesics, both oral and topical. Here we report a case of HZ in an 80-year-old woman involving maxillary nerve and the article also reviews various treatment modalities available for the management of HZI.
