Pityriasis rosea is a self-limited inflammatory condition of the skin that mostly affects young adults . Several less common atypical presentations have been reported .A 6 -year old girl with red -brown maculopapular eruption sized 0 , 5 -1 cm in diameter localized on neck , trunk and popliteal region visited our general pediatric outpatient clinic . The eruption was wide spread especially on flexural areas . After consulting dermatologist skin biopsy was performed . According to clinical and histopathological findings as inverse (flexural ) pityriasis rosea was diagnosed . For treatment , systemic antihistamine , topical corticosteroid cream and emollient were applied . The lesions healed in two months . Spontaneous healing of the eruption also confirmed the diagnosis of pityriasis rosea .We present this interesting pediatric case to show and discuss pityriasis rosea , atypical presentations , differential diagnosis and the importance of dermatological examination and importance of dermatologic consultation for pediatric patients with skin eruption .
