Herpes zoster presenting as unilateral vasculitis

Author(s): Clark, Ashley K; Dhossche, Julie; Korcheva, Veselina B; Keller, Jesse J | Abstract: Vasculitis can be a primary disorder or a cutaneous manifestation of a viral infection. The present case describes an atypical localized cutaneous varicella-zoster virus infection inducing a small vessel vasculitis in a patient with multisystem sarcoidosis. Additionally, we discuss the differential diagnoses and treatment options. Varicella-Zoster infection occurs more frequently in immunosuppressed populations and can present with uncharacteristic clinical manifestations complicating the diagnosis as in the present case.
