文献摘要 全文翻译

A woman in her 40s with a history of atopy presented with a 1-year history of asymptomatic red-brown patches on the distal extensor extremities. The lesions began on the bilateral lower legs and spread to the thighs, buttocks, hands, forearms, and proximal arms. Physical examination revealed numerous stellate red brown patches without induration, scale, or ulceration (Figure, A). Review of systems was notable for episodic muscle cramping and numbness involving the lower extremities. The patient had no notable recent medical illnesses, illicit drug use, or new medications. An incisional wedge biopsy was performedona lesion from the lower extremity, and the specimen was stained with hematoxylin-eosin (Figure, B and C).

患者女性,40余岁,有特应性病史,1年前四肢远端出现无症状红棕色斑块。皮损开始于双下肢,并蔓延至大腿、臀部、双手、前臂和手臂近端。体格检查发现大量星状红棕色斑块,无硬结、鳞屑或溃疡(图A)。值得注意的是系统评估示受累下肢偶发性肌肉痉挛且有麻木感。该患者近期无明显疾病史、非法使用药物或使用新药物史。从下肢取标本进行穿刺活检,并对标本进行HE染色(图B和C)。
