An Unusual Rash in a Febrile Adult
Abstract
We report a 38-year-old man who presented with nonpruritic flagellate erythema, symmetrical polyarthritis, daily high-grade fevers, and unintentional weight loss. Skin biopsy supported the diagnosis of adult-onset Still disease (AOSD), which was established after exclusion of alternative diagnoses. The patient improved with oral corticosteroid therapy. Flagellate erythema is a rare cutaneous manifestation of AOSD, which may delay diagnosis. Awareness of this presentation is important for timely recognition and management.
