We report the case of a twelve-year-old male who presented with isolated anterior cervical hypertrichosis persistent since birth. No notion of trauma or local inflammation or the use of a topical treatment was noted. The patient had no other clinical symptoms and no similar family history.

A clinical examination found a tuft of hair, approx. 6 × 3 cm in size, at the level of the mid-neck region, consisting of fine, brown hairs, 3 cm in length (Fig. 1a), with a dermoscopic appearance showing terminal hair and fluffy hair without other associated signs. (Fig. 1b). The rest of the somatic examination was unremarkable. A laser hair removal treatment was offered to the patient with a good response.

Anterior cervical hypertrichosis is a rare form of congenital localized hypertrichosis. To date, around forty cases have been reported worldwide [1]. Clinically, it is characterized by a tuft of terminal hairs located in the anterior cervical region.

It may sometimes be associated with neurological, orthopedic, or ocular abnormalities. The most common association is with motor and sensory neuropathy, followed by hallux valgus, optic atrophy, chorioretinopathy, mental retardation, and localized dorsal hypertrichosis. Familial and sporadic cases have been reported [2].

The management of isolated anterior cervical hypertrichosis is cosmetic. Laser hair removal is the best recommended treatment, with an estimated response of 70% [3].
