Prurigo pigmentosa (PP) is a rare inflammatory dermatosis of unknown cause characterized by a predominantly truncal eruption of pruritic erythematous papules in a reticular pattern, resolving with hyperpigmentation. PP is twice as common in girls and women, and the mean age at onset is 25 years. Diagnosis of PP is challenging and is aided by characteristic histopathologic findings. We report a case of PP in a 17-year-old white boy. The eruption arose during strict adherence to a ketogenic diet.
色素性痒疹（PP）是一种病因不明的罕见炎症性皮肤病，其特征主要为躯干出现呈网状分布的瘙痒性红斑丘疹，消退后会出现色素沉着。PP在女孩和女性中更为常见，发病率是男性的两倍，平均发病年龄为25岁。PP的诊断具有挑战性，典型的组织病理学表现有助于诊断。我们报告一例17岁白人男孩患色素性痒疹的病例。皮疹出现在严格遵循生酮饮食期间。
