Granulomatous pigmented purpuric dermatosis (GPPD) is a rare histologic variant of pigmented purpuric dermatosis (PPD). It includes classic histology changes of PPD with superimposed granulomas. This variant is thought to be associated with hyperlipidemia and is found predominantly in individuals in the Far East; however, a review of the literature that included 26 documented cases of GPPD revealed these associations might be becoming less clear. We report a case of GPPD in an elderly white man who had an eruption involving the majority of the lower legs.
肉芽肿性色素性紫癜性皮病（GPPD）是色素性紫癜性皮病（PPD）一种罕见的组织学变异型。它包括PPD的典型组织学改变并伴有肉芽肿形成。这种变异型被认为与高脂血症有关，主要见于远东地区的人群；然而，一项对26例有记录的GPPD病例的文献回顾显示，这些关联可能变得不那么明确了。我们报告一例老年白人男性GPPD病例，其皮疹累及大部分小腿。
