颊疹(又叫蝴蝶斑,因其位于两颊呈蝴蝶状)提示狼疮.盘状红斑狼疮(DLE)与(系统性红斑狼疮)SLE相比相对轻些,主要表现在皮肤上。两者暴晒于阳光下都可以加速红斑的产生.一小部分DLE患者大约(5-10%)发展成SLE.(通常DLE 患者抗核抗体为阳性).
The young woman has a malar rash (the so-called "butterfly" rash because of the shape across the cheeks). Such a rash suggests lupus. Discoid lupus erythematosus (DLE) involves mainly just the skin and is, therefore, relatively benign compared to systemic lupus erythematosus (SLE). In either case, sunlight exposure accentuates this erythematous rash. A small number (5 to 10%) of DLE patients go on to develop SLE (usually the DLE patients with a positive ANA).
