This case reviews an eruption of herpes zoster (shingles) in an inpatient. It examines the clinical presentation, pathophysiology, and treatment of this condition. Herpes zoster is an acute, painful vesiculobullous eruption that is seen most commonly in older adults in the setting of previous exposure to varicella zoster virus. Classic features include painful vesicles on well-defined erythema, typically confined to a single dermatome. Initiation of antiviral therapy within 72 hours of the onset of skin lesions is given to reduce the duration of the eruption and decrease the incidence of postherpetic neuralgia. This case will also review how herpes zoster differs from other cutaneous eruptions that may look similar, such as herpes simplex or Stevens Johnson syndrome.
