Prurigo pigmentosa is a rare inflammatory dermatosis that predominantly affects East Asian populations, with very few reported cases in individuals with darker skin tones. The condition is characterized by pruritic, erythematous papules that evolve into a distinct, net-like pattern of hyperpigmentation. Due to its rarity in non-Asian populations, prurigo pigmentosa is often underdiagnosed or misclassified as other hyperpigmented dermatoses. We present the case of a 33-year-old African-Canadian woman who developed prurigo pigmentosa following prolonged fasting, contributing to the limited literature on this condition in skin of color. This report aims to raise awareness of prurigo pigmentosa in underrepresented populations.
色素性痒疹是一种罕见的炎症性皮肤病,主要影响东亚人群,肤色较深的个体中报告的病例极少。该病的特征是瘙痒性红斑丘疹,可演变成独特的网状色素沉着模式。由于色素性痒疹在非亚洲人群中罕见,它常被漏诊或误诊为其他色素沉着性皮肤病。我们报告了一例33岁的非裔加拿大女性病例,该患者在长期禁食后患上了色素性痒疹,这为关于这种疾病在有色人种皮肤中的有限文献增添了内容。本报告旨在提高对色素性痒疹在代表性不足人群中的认识。
