Core Tip

Core Tip: Disseminated herpes simplex virus-1 is a rare but potentially life-threatening complication in erythrodermic psoriasis treated with biologics. This case highlights diagnostic ambiguity in inflamed skin, the impact of cumulative immunosuppression, and the absence of standardized guidance on when and how to safely reintroduce biologic therapy after viral resolution.
