Eccrine angiomatous hamartoma: a multiple variant

A case of multiple eccrine angiomatous hamartoma present in a boy since birth is reported. Clinically, this condition must be differentiated from other neonatal angiomatoses. Sometimes the clinical findings are nonspecific, whereas histologic examination may exclude angiomatoses with visceral involvement. In our case the hamartomatous nature of this tumor is documented also by the presence of pilar structures intimately related to the eccrine-angiomatous complex in one of two lesions histologically examined. Therefore, the histologic classification of eccrine angiomatous hamartoma into subgroups seems to be excessive.
