title: Herpes Zoster Duplex Unilateralis: Two Cases and Brief Literature Review.
abstract: Cases involving dermatomal herpes zoster in two or more locations are rare, especially in immunocompetent patients. When two noncontiguous dermatomes are involved, if affected unilaterally, it is called herpes zoster duplex unilateralis; if bilaterally, bilateralis. Here, we report two cases of herpes zoster duplex unilateralis. A 66-year-old man presented with painful erythematous grouped vesicles on his left scalp, forehead, trunk, and back (left [Lt.] V1, Lt. T8). Histologic findings were consistent with herpetic infection. A 33-year-old woman presented with painful erythematous grouped vesicles and crust on her left forehead and neck (Lt. V1, Lt. C5). Both patients were treated with oral administration of famcyclovir 750 mg/day for seven days.
