Accessory tragus is a fairly common congenital malformation of the external ear. However, it is extremely difficult to make a distinction between accessory tragus without cartilage and hair follicle nevus. Hair follicle nevus is an extremely rare adnexal hamartoma with follicular differentiation that commonly presents as a nodule on the face.
