Adult-onset Still disease (AOSD) is a systemic inflammatory disorder characterized clinically by high spiking fever, polyarthralgia/arthritis, a salmon-pink evanescent rash, predominantly neutrophilic leucocytosis, lymphadenopathy, liver dysfunction, and splenomegaly. Recently, a nonclassic, nonevanescent skin rash has been reported. We report a 27-year-old woman with AOSD showing persistent pruritic papular lesions. Histologically, dyskeratotic keratinocytes were seen in the upper epidermis. We describe this case in detail and review the previous literature. Nonclassic pruritic eruptions with characteristic dyskeratotic keratinocytes might provide an important clue for the diagnosis of AOSD.
