Anterior cervical hypertrichosis: A rare entity

A 15-year-old girl was referred to our outpatient clinic with a patch of excessive hair growth on the anterior neck just above the laryngeal prominence. Her parents noticed the hairy patch when she was 1 year old and reported that the hair had progressively increased in density and length as the child grew. Her past medical history revealed no known comorbidities. On physical examination, a tuft of fine, long, black terminal hair was visible over the anterior neck forming a patch of approximately 3 × 2 cm at the midline of neck above laryngeal prominence [Figures 1a and 1b]. Anterior cervical hypertrichosis might be a cosmetic problem. But it may also be associated with significant neurologic and ophthalmologic implications, most common being peripheral and sensory motor neuropathy, optic atrophy and chorioretinal changes. The patient was referred to neurologist and ophthalmologist for further assessments. The patient and her parents did not have any cosmetic concern. Therefore, no treatment was offered to the patient.
