Lichen aureus is a variant of pigmented purpuric dermatoses. The usual histopathology of lichen aureus is characterized by a subepidermal dense, band-like lymphocytic infiltrate, extravasated erythrocytes, and hemosiderin deposits. We report three patients with lichen aureus on the extremities with similar clinical, dermoscopic, and histopathological findings characterized by a dense band-like relatively deep dermal infiltrate accompanied by extravasation of erythrocytes and hemosiderin deposits occasioning a resemblance to a lymphoproliferative disorder.
金黄色苔藓是色素性紫癜性皮肤病的一种变异型。金黄色苔藓的常见组织病理学特征是表皮下致密的、带状的淋巴细胞浸润、红细胞外渗和含铁血黄素沉积。我们报告了 3 例发生在四肢的金黄色苔藓患者，其临床表现、皮肤镜和组织病理学表现相似，表现为致密的、相对较深的带状真皮浸润，伴有红细胞外渗和含铁血黄素沉积，类似于淋巴增生性疾病。
