定义
慢性皮肤红斑狼疮（LE）的特点是出现局限性皮肤斑块，表现为不同程度的水肿、红斑、脱屑、毛囊堵塞和萎缩。最常见的表现是盘状斑块，累及面部、耳朵和头皮，但也可广泛播散，或主要影响四肢（冻疮性LE）或皮下脂肪（狼疮脂膜炎）。它可引起明显的毁容，明显面部瘢痕和永久性脱发。大多数患者健康状况良好，但5-10%的病人可能发展为系统性红斑狼疮。与亚急性皮肤红斑狼疮相比，光敏性不明显。
Chronic cutaneous lupus erythematosus (LE) is characterised by the presence of circumscribed cutaneous plaques showing varying degrees of oedema, erythema, scaling, follicular plugging and atrophy. It most commonly presents as discoid plaques involving the face, ears and scalp but can be widely disseminated or may affect predominantly the extremities (chilblain LE) or subcutaneous fat (lupus panniculitis). It can cause marked disfigurement with prominent facial scarring and permanent hair loss. Most patients remain otherwise in good health but 5-10% may develop systemic lupus erythematosus. Photosensitivity is less apparent than in subacute cutaneous lupus erythematosus.
