Abstract：
Discoid lupus erythematosus (DLE)-associated edema and erythema on the lower eyelid as the only manifestation of the disease is a rare clinical entity. Persistent discoid lupus-related lower eyelid manifestations are challenging to diagnose, can be mistaken for blepharitis or malignancies, and often require histopathological evaluation. If left untreated, the condition can progress, among others, to conjunctival scarring or symblepharon formation. Thus, early identification and management of the disease entity is of the utmost significance. We present a rare case of a young patient with enduring, unilateral lower eyelid edema and erythema that had been managed as blepharitis for several years. No other related cutaneous involvement was detected on the eyelids, face, or body. Following a lower eyelid biopsy and histopathological assessment, the patient was diagnosed with underlying DLE. This case report reviews the previous literature, discusses a differentiation strategy from other relevant pathologies, such as blepharitis and sebaceous cell carcinoma, and highlights the implemented diagnostic procedures.
摘要：
盘状红斑狼疮（DLE）相关的下眼睑水肿和红斑作为该疾病的唯一表现是一种罕见的临床实体。持续盘状狼疮相关的下眼睑表现难以诊断，可能会被误认为眼睑炎或恶性肿瘤，通常需要进行组织病理学评估。如果不及时治疗，情况可以进展，其中,结膜结膜瘢痕形成或眼睑形成。因此，疾病实体的早期识别和管理至关重要。我们介绍了一个罕见的年轻患者，单侧下眼睑水肿和红斑，已被治疗为眼睑炎数年。在眼睑上没有发现其他相关的皮肤受累，脸,或身体。下眼睑活检和组织病理学评估后，患者被诊断为潜在的DLE。本病例报告回顾了以往的文献，讨论了与其他相关病理的差异化策略，如眼睑炎和皮脂腺细胞癌，并重点介绍了已实施的诊断程序。
