CASE PRESENTATION

A 4-year-old girl presented with a 10-month history of asymptomatic red lesions on her palms. Since appearing, the lesions had not changed. Her parents did not recall any specific incident of trauma to her palms. In addition, they denied any preceding illness, swelling, hives, trouble swallowing, epistaxis, ataxia, cold sensitivity, or Raynaud's phenomenon. She had a remote history of neonatal lupus erythematosus (NLE), having been born to an anti-Ro antibody-positive mother. Complete cardiologic evaluation at birth was normal with no signs of heart block. In infancy, cutaneous NLE involving the lateral scalp and neck was treated with triamcinolone cream, resulting in resolution of those lesions. Family history was negative for sclerodactyly.

On examination, there were blanchable red macules on her bilateral hypothenar eminences that appeared vascular under dermoscopy (Figures 1 and 2). There was no involvement of the oral mucosa, no similar lesions were noted elsewhere on her skin, and no other cutaneous findings were noted. Antinuclear antibody (ANA) and extractable nuclear antigen (ENA) profiles were negative.

一名 4 岁女孩的手掌毛细血管扩张症

案例展示

一名 4 岁女孩，因手掌出现无症状红色皮损 10 个月就诊。自出现以来，病变一直没有改变。她的父母不记得她的手掌有任何具体的外伤事件。此外，他们否认之前有任何疾病、肿胀、荨麻疹、吞咽困难、鼻出血、共济失调、冷敏感或雷诺现象。她有新生儿红斑狼疮 (NLE) 的遥远病史，她的母亲是抗 Ro 抗体阳性的母亲。出生时完整的心脏评估是正常的，没有心脏传导阻滞的迹象。在婴儿期，涉及外侧头皮和颈部的皮肤 NLE 用曲安奈德乳膏治疗，导致这些病变消退。家族史对硬指病阴性。

检查时，她的双侧小鱼际隆起有发白的红色斑块，在皮肤镜检查下呈血管状（图 1 和图 2）。口腔黏膜未受累，皮肤其他部位未发现类似病变，也未发现其他皮肤发现。抗核抗体 (ANA) 和可提取核抗原 (ENA) 谱均为阴性。
