A Case of Eccrine Angiomatous Hamartoma / 대한피부과학회지

ABSTRACT

Eccrine angiomatous hamartoma is a distinct developmental anomaly showing, histologically, hyperplasia of eccrine sweat apparatus and of vascular elementa in the same lesion, and clinically, the angiomatous lesions with occasional tenderness and profuse local sweating. Recently, we examined an 18-year-old, otherwise healthy girl having, on the anterior aspect of the right leg, an extensive, irregularly marginated and somewhat bluish, tender, firm subcutaneous mass. The mass was studded with several overlying macular, verrucous or nodular angiomatous patches which showed conspicuous hyperhidrosie. Histological examination revealed marked hyperplasia, hypertrophy and cystic dilatations of eccrine sweat apparatus accompanied by proliferation of the capillary hemangiomatous component and ectopic, thick smooth muscle bundles in the deep dermis and subcutaneous tissue.
