Eccrine angiomatous hamartoma (EAH) is an exceedingly rare benign tumor-like lesion prevalent in childhood which may produce pain and marked sweating. The histological features include proliferation of eccrine sweat glands and angiomatous capillary channels. We report an 8-year-old girl who had a single lesion on her left lower leg. Physical examination revealed a slightly elevated, 4×7 cm erythematous plaque on the lateral aspect of left leg. Sweating in the lesion was evoked by physical work or emotional stress. There was no pain or tenderness associated with the lesion. The patient had no history of trauma to the site. These lesions were clinically angiomatous, and we obtained the diagnosis by histopathological examination. Histopathological examination of the lesion showed increased numbers of eccrine glands, as well as dilated vascular channels in the deep dermis and subcutaneous tissue. These findings are consistent with EAH.
小汗腺血管瘤样错构瘤（EAH）是一种极为罕见的良性肿瘤样病变，多见于儿童期，可引起疼痛和明显出汗。组织学特征包括小汗腺和血管瘤样毛细血管通道的增生。我们报告一名8岁女孩，其左小腿有单个病变。体格检查发现左腿外侧有一个略隆起的4×7厘米红斑。病变部位的出汗可由体力活动或情绪紧张诱发。病变部位无疼痛或压痛。患者该部位无外伤史。这些病变在临床上表现为血管瘤样，我们通过组织病理学检查确诊。病变的组织病理学检查显示小汗腺数量增加，真皮深层和皮下组织的血管通道扩张。这些发现与小汗腺血管瘤样错构瘤相符。
