Asymmetric Herpes Zoster Duplex Bilateralis in an Immunocompetent Patient

Abstract Herpes zoster (HZ) is a common disorder of elderly patients presenting to primary care physicians and dermatologists. It is classically confined to a single dermatome but two or more contiguous dermatomes are often involved in immunocompromised patients and less frequently in immunocompetent patients. However, the simultaneous occurrence of HZ at two noncontiguous dermatomes is rare and is called HZ duplex (HZD). The dermatomes involved can be unilateral which is termed HZD unilateralis or bilateral which is termed HZD bilateralis (HZDB). These atypical manifestations are rarely reported in immunocompetent as well as immunosuppressed patients. We report a case of asymmetric HZDB in a 51-year-old immunocompetent patient, which is very rare.
