Abstract:
Eccrine angiomatous hamartoma (EAH) is a rare, benign cutaneous tumor. It is characterized by the proliferation of the eccrine gland elements that are closely associated with capillary proliferation. Patients usually present with a solitary nodule on the extremities that appeared at birth or during the prepubertal years. We report a rare case of EAH in a 13-year-old boy, with clinical features suggesting melanoma. Histologically, an EAH with changes resembling a verrucous hemangioma was noted.

The dermis might be considered the "core" of the integumentary system, as distinct from the epidermis and hypodermis. It contains blood and lymph vessels, nerves, and other structures, such as hair follicles and sweat glands. The dermis is made of two layers of connective tissue that comprise an interconnected mesh of elastin and collagenous fibers, produced by fibroblasts.

The papillary layer is made of loose, areolar connective tissue, which means the collagen and...
