Pityriasis rubra pilaris (PRP) is an uncommon, idiopathic, papulosquamous eruption. We report a longitudinal study of a patient with PRP type 1 who was treated with retinoid therapy for 9 years and whose symptoms resolved spontaneously after 20 years. There are no data in the literature on the disease course of PRP type 1 persisting beyond the usual 3 years. This case highlights both the extreme chronicity of PRP and the possibility of remission after many years of active disease.
红皮病型毛发红糠疹（PRP）是一种罕见的特发性丘疹鳞屑性皮疹。我们报告了一项对1型PRP患者的纵向研究，该患者接受维甲酸治疗9年，其症状在20年后自发缓解。文献中没有关于1型PRP病程超过通常3年的相关数据。该病例既凸显了PRP的极度慢性病程，也显示了在多年的活动性疾病后缓解的可能性。
