The eccrine angiomatous hamartoma (EAH) is a rare, benign adnexal tumor. It represents a mix of eccrine structures intermingled with angiomatous capillary channels. There is a spectrum. When the angiomatous component predominates, the term sudoriparous angioma has been used. When the eccrine component predominates, the term eccrine nevus has been used.


A bluish-red, soft nodule presents at birth or early in life which may be painful or may sweat is characteristic. Lesions have been reported on almost all areas of the body. These lesions may be clinically indistinguishable from a hemangioma. One with a verrucous appearance has been reported [BJD 1999;141;167].


Spontaneous resolution often occurs. Excision of a painful lesion on the sole has been done.
