Hair follicle nevus is a cutaneous condition that presents as a small papule from which fine hairs protrude evenly from the surface.[1]
Hair follicle nevus usually presents as a single, skin-colored papule or nodule on the face after birth that exhibit no symptoms.[2]
Histologically, vellus hair follicle growth with perifollicular fibrous thickening occasionally encircled by a cellular stroma is the hallmark of hair follicle nevus. Smooth muscle fibers and eccrine and sebaceous glands are at times visible.[2]
