Erythema elevatum diutinum (EED) is a rare cutaneous neutrophilic vasculitis with many associated diseases reported in the literature. We report a 65-year-old woman with painful and itchy lesions on her elbows, hands, knees, and foot for a year. Histopathologic examination confirmed the diagnosis of erythema elevatum diutinum and treatment with dapsone produced significant clinical improvement within few weeks. Erythema elevatum diutinum is a rare disease that should be considered in patients with violaceous nodular plaques located over the extensor regions of the limbs. Knowledge of this unusual pathology and its association helps to avoid misdiagnosis and late treatment.
持久性隆起性红斑（EED）是一种罕见的皮肤中性粒细胞血管炎，文献中有许多相关疾病的报道。我们报告了一位 65 岁女性，她肘部、手部、膝盖和脚部有疼痛和瘙痒的病变，已经持续了一年。组织病理学检查证实了持久性隆起性红斑的诊断，并且在几周内，使用氨苯砜治疗后，患者的临床症状得到了显著改善。持久性隆起性红斑是一种罕见的疾病，对于位于四肢伸侧部位的紫红色结节斑块患者，应考虑该疾病。了解这种不常见的病理及其相关性有助于避免误诊和延迟治疗。
