Circumscribed juvenile pityriasis rubra pilaris.
We report the case of a 20-year-old woman with a 10-year history of circumscribed juvenile-onset pityriasis rubra pilaris (PRP, type IV). Our patient had well-defined keratotic follicular papules on an erythematous base located on the extensor aspects of the extremities and dorsal aspects of the feet but no involvement of the palms and soles. Although most cases of type IV PRP follow a favourable course with spontaneous resolution of the lesions, this case demonstrates that circumscribed juvenile PRP can be more persistent and lasts several years.
