Eccrine angiomatous hamartoma.

A 7-year-old girl presented with asymptomatic bruise-like hairy nodules on her right lower leg since 8 months of age. Histopathology demonstrated an increased number of blood vessels and eccrine glands, thicker collagen bundles, and a terminal hair follicle in catagen phase. The patient was diagnosed with multiple eccrine pilar angiomatous nevi, an unusual variant of eccrine angiomatous hamartomas. The natural course of eccrine angiomatous hamartomas is typically slow growth and benign behavior. Simple excision is usually curative and is reserved for painful or cosmetically disfiguring lesions. Our patient's nevus is large and multifocal, making excision more challenging.
