Herpes Zoster Duplex Symmetricus in a Healthy Patient / 대한피부과학회지

ABSTRACT

Herpes zoster duplex, particularly herpes zoster duplex symmetricus, is a very rare manifestation of herpes zoster that occurs in immunocompetent patients. A 23-year-old Korean man presented with grouped erythematous, ruptured, crusted vesicles on plaques and papules on his forehead and both temporal areas. He had unexplained pain around the cutaneous lesions for the past 2 weeks, and the vesicles developed 1 week ago. A Tzanck smear test of the skin lesion showed multinucleated giant cells. A punch biopsy taken from the vesicle on the forehead revealed an intraepidermal vesicle with acantholysis and balloon cells at the floor of the vesicle. He was diagnosed with herpes zoster involving bilateral dermatomes.
