We present the case of a 9-year-ol, phototype 3, who attended a specialized dermatology consultation at the William Soler pediatric hospital due to erythematosquamous lesions arranged in plaques located on both knees accompanied by palmoplantar keratoderma. Laboratory tests and skin biopsies were carried out, concluding case as a juvenile and circumscribed pityriasisrubra pilaris. This is an infrequent dermatosis, a therapeutic challenge because of the absence of international standardized treatments and it has an unpredictable evolution.
