Rosacea fulminans following initiation of deucravacitinib

Rosacea fulminans developed in a middle-aged White man 10 days after initiating deucravacitinib for chronic plaque psoriasis. The painful papulopustular eruption resolved without scarring after discontinuation of deucravacitinib and treatment with a short course of oral prednisolone. To our knowledge, this case is notable as it is the first reported instance of rosacea fulminans linked to the use of a Janus kinase inhibitor.
