Herpes simplex virus type 1 (HSV-1) is a common DNA virus that typically causes orolabial lesions. Atypical presentations, such as dermatomal vesicular eruptions, are rare and may mimic varicella-zoster virus (VZV) reactivation, complicating diagnosis. Here we present a case of HSV-1 with recurrent vesicular eruptions in the C4-C5 dermatomes, initially posited to be herpes zoster. Viral culture confirmed HSV-1, and the patient’s symptoms were successfully managed with valacyclovir and topical corticosteroids.
