Signs and symptoms

edit

Hair follicle nevus usually presents as a single, skin-colored papule or nodule on the face after birth that exhibit no symptoms.[2]

Diagnosis

edit

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]
