A Case of Herpes Zoster Duplex Bilateralis / 대한피부과학회지

ABSTRACT

Herpes zoster classically occurs unilaterally within the area of skin innervated by a single sensory ganglion. Simultaneous involvement of two noncontiguous dermatomes is very rare and it has been referred to as zoster duplex unilateralis or bilateralis, depending whether one or both halves of the body are involved. A 47-year-old woman presented with painful grouped vesicles on the right chest and the left lower back. The tzanck smear and the skin biopsy were consistent with herpetic infection. She was treated with intavenous acyclovir without any significant complications. We report a rare case of zoster duplex bilateralis.
