线状皮肤型红斑狼疮六例

目的 探讨线状皮肤型红斑狼疮(LCLE)临床和组织病理学特点.方法 回顾分析6例LCLE的临床和病理学特点.结果 LCLE多单侧发病,表现为带状或线状分布的暗红斑,伴毛细血管增生扩张,部分黏着性鳞屑.组织病理学诊断依据为真皮浅、深丛细血管周围及毛囊、皮脂腺、汗腺周围有致密团块状淋巴细胞浸润,部分病例可见表皮角化不全,毛囊角栓,基底细胞液化变性,类似盘状红斑狼疮组织像.治疗以氯喹为首选,对于皮疹范围较广泛,且组织病理改变见淋巴细胞浸润达真皮深部甚至皮下脂肪小叶处的患者,给予小剂量糖皮质激素治疗疗效明显.结论 LCLE诊断需要结合临床和组织病理.

Clinical manifestation and histopathologic features of linear cutaneous lupus erythematosus: a report of six cases

Objective To summariza the clinical and histological features of linear cutaneous lupus erythematosus (LCLE).Methods Six cases of LCLE were analyzed retrospectively.Results LCLE was often clinically characterized by unilateral.zonal or linear,dark-erythematous patches with telangiectasia,and some lesions were covered with adherent Scales.Histologically,there were patchy perivascular and periadnexal lymphoid inflammatory infiltrate occurring in the superficial and deep dermis.Some cases were pathologically manifested by parakeratosis of superficial dermis,follicular plugging and hydropic degeneration of the basal layer of the epidermis,which was characteristic of discoid lupus erythematosus.The preferred treatment was chloroquine for LCLE.Low dose of corticosteroids were recommended for widespread lesions,especially for those pathologically manifested by lymphocyte infiltrates in the lower dermis and fat tissue.Conclusion The diagnosis of LCLE should be based on clinical and histopathological manifestations.
