Prurigo Pigmentosa is a rare inflammatory skin disease of unknown origin, characterized by pruritic, erythematous papules on the chest, back, neck, and anterior abdomen. The eruption resolves with reticular hyperpigmentation that cosmetically affects the patient's quality of life. Previous reports highlighted the role of the Ketogenic diet in triggering the disease in young female patients, however, no study reported the occurrence of Prurigo Pigmentosa in siblings of one family, unrelated to a ketogenic diet. Here, we report two sisters diagnosed with Prurigo Pigmentosa without undergoing a Ketogenic diet.
色素性痒疹是一种病因不明的罕见炎症性皮肤病,其特征为胸部、背部、颈部和前腹部出现瘙痒性红斑丘疹。皮疹消退后会留下网状色素沉着,这在外观上影响患者的生活质量。既往报道强调了生酮饮食在年轻女性患者中引发该病的作用,然而,尚无研究报道过一个家族中与生酮饮食无关的兄弟姐妹发生色素性痒疹的情况。在此,我们报告两姐妹被诊断为色素性痒疹,她们并未采用生酮饮食。
