Pigmented purpuric lichenoid dermatitis (PPLD) is a rare subtype of pigmented purpuric dermatosis, which classically presents with a mixture of lichenoid papules and patches on the bilateral lower extremities. Herein, we describe an unusual case of a 47-year-old man with PPLD who presented with 1-3mm discrete papules without the presence of larger patches. The diagnosis of PPLD should be considered for patients presenting with bilateral symmetric discrete papules on the legs.
色素性紫癜性苔藓样皮炎（PPLD）是一种罕见的色素性紫癜性皮肤病的亚型，其经典表现为双侧下肢存在混合性苔藓样丘疹和斑块。在此，我们描述了一例不典型的 47 岁男性 PPLD 患者，其表现为 1-3mm 的离散丘疹，而无更大斑块存在。对于腿部双侧对称存在离散丘疹的患者，应考虑 PPLD 的诊断。
