Adult-onset Still’s disease with dermatomyositis-like lesions

In the early stages of adult-onset Still's disease, diagnosis can be challenging due to the lack of specific findings. In many cases, it is diagnosed by excluding other differential diagnoses.Cutaneous manifestations play a crucial role in correctly identifying the disease. The typical rash is a transient, salmon-coloured maculopapular eruption that coincides with fever spikes.However, atypical cutaneous manifestations such as dermatomyositis-like lesions, urticarial eruptions, persistent plaques, polymorphic erythema and lichenoid lesions, have been reported. These atypical skin findings may be associated with a more severe disease course, making early recognition essential for prompt diagnosis and treatment.
