Eccrine angiomatous harmartoma in an infant.

Eccrine angiomatous hamartoma is a nevoid proliferation of eccrine glands and small vessels. It usually presents as a solitary, slow growing nodule, manifesting at birth or in childhood, which can be accompanied by hyperhidrosis and pain on palpation. We report an occurrence in an otherwise healthy 3-month-old girl who had multiple, asymptomatic, nodular lesions with a linear arrangement localized to the inguinal fold. We also review the literature on adnexal hamartomas of infancy.
