Abstract
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.
