Full Definition
Eczema herpeticum is a potentially serious disseminated herpes simplex virus infection that occurs in patients with pre-existing atopic dermatitis or other inflammatory skin conditions. The infection presents as rapidly spreading, punched-out vesicles and erosions with hemorrhagic crusting, often accompanied by fever and lymphadenopathy. The condition represents a dermatologic emergency requiring prompt recognition and systemic antiviral therapy to prevent complications including viremia, encephalitis, and keratoconjunctivitis. Medical writers should understand the urgency of diagnosis and treatment, particularly in pediatric patients who may develop severe systemic complications.
