Herpes Zoster Duplex Bilateralis in a Patient with Breast Cancer

Abstract

The skin lesion of herpes zoster is classically limited to a single dermatome, and most cases of multi-dermatomal herpes zoster have contiguous skin lesions. Noncontigous multi-dermatomal herpes zoster is very rare in both immunocompetent and immunosuppressed persons. The phenomenon of zoster occurring in two non-contiguous dermatomes has been referred to as zoster duplex unilateralis or bilateralis. We report here on a case of herpes zoster duplex bilateralis in a 49-year-old woman who had previously received chemotherapy for breast cancer treatment.
