Granulomatous pigmented purpuric dermatosis (PPD) is a rare and poorly recognized histological variant of PPD, which commonly affects the distal extremities of mainly Far East Asian patients. Many of the reported cases are associated with hyperlipidemia or other associated systemic derangements. The authors hereby describe an additional case of granulomatous PPD affecting a 56-year-old Caucasian woman presenting unusually as a solitary lesion confined to the lower back. The report also describes dermoscopic findings, summarizes clinicopathological features of all the cases published till date, and discusses the histopathological differential diagnosis.
肉芽肿性色素性紫癜性皮病（PPD）是一种罕见且认识不足的PPD组织学变异型，主要影响远东地区患者的远端肢体。许多报道的病例与高脂血症或其他相关的全身紊乱有关。作者在此描述了另一例肉芽肿性PPD病例，患者为一名56岁的白种女性，表现为局限于下背部的孤立性病变，情况较为罕见。该报告还描述了皮肤镜检查结果，总结了迄今为止已发表的所有病例的临床病理特征，并讨论了组织病理学鉴别诊断。
