A clinical case of pityriasis rubra pilaris - juvenile type

Pityriasis rubra pilaris is a rare chronic inflammatory papulo-squamous skin disease, the pathogenesis of which is still unclear. The pathological essence of the disease is associated with a violation of keratinization against the background of hyperactivity of keratinocytes with subsequent inflammation, as well as with vitamin A dysmetabolism and a weakening of the protein-binding fiction of the liver.
