Hair follicle nevus

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.
