Herpes zoster in seven disparate dermatomes (zoster multiplex): Report of a case and review of the literature

Noncontiguous multidermatomal herpes tester is very rare in both immunocomp etent and immunocompromised persons. Most of the reported cases have been l imited to 2 noncontiguous dermatomes. This unique presentation has been ref erred to as tester duplex uni lateralis or bilateralis, depending on whethe r one or both halves of the body are involved. Granulomatous dermatitis at sites of herpes tester scars, a rare isotopic response, has only been repor ted in persons with contiguous dermatomes of tester. We describe an immunoc ompromised patient who developed herpes tester in 7 disparate dermatomes. T hree months after resolution of the tester, the patient developed a granulo matous dermatitis in a zosteriform distribution at the sites of previous in fection.
