RESUMO
The diagnosis of adult onset Still's disease is usually based on a symptom complex and the well-described typical rash, seen in most patients [Still's rash]. Other cutaneous manifestations of adult onset Still's disease have been reported but these are not well known. This case report describes the occurrence of an atypical skin eruption [prurigo pigmentosa] in a young female with adult onset Still's disease in the absence of the classic evanescent rash of Still's disease. The association of prurigo pigmentosa and adult onset Still's disease is extremely rare and only a single case report exists in the English literature. Therefore, we should carefully follow the clinical course of a patient in order not to overlook these atypical cutaneous manifestations of adult onset Still's disease
