Adult-Onset Still’s Disease Presenting as an Atypical Cutaneous Eruption

Adult-onset Still’s disease classically presents with high fevers, arthralgias, leukocytosis, and an evanescent eruption. There are, however, a known subset of patients who develop an atypical eruption with persistent erythematous to violaceous papules and plaques. Here, we present the case of a white female in her 40s who presented with 2 years of spiking fevers, arthralgias, and a fixed pruritic eruption with erythematous plaques with overlying scale and linear accentuation. She was initially treated with oral prednisone, anakinra, and methotrexate. Due to persistent symptoms, she was switched to adalimumab with significant relief of symptoms. Prompt recognition of adult-onset Still’s disease with this atypical eruption may help prevent delayed or missed diagnosis and allow for early, appropriate intervention.
