Anterior Cervical Hypertrichosis (Hairy Throat Syndrome): Pediatric Case Report and Brief Literature Review

Anterior cervical hypertrichosis, also known as hairy throat syndrome, is a rare and typically benign condition characterized by a well-defined patch of terminal hair on the front of the neck. Although it is often an isolated finding, it may sometimes be associated with neurological or developmental abnormalities, which makes clinical awareness important. We report the case of a healthy 4-year-old girl who presented with congenital localized excessive hair growth over the anterior cervical region. The patch had remained unchanged since birth and was not associated with any skin changes or systemic symptoms. Her physical and neurological examinations were normal, and imaging studies ruled out underlying spinal or soft tissue anomalies. Although she had a resolved history of ptosis and was under follow-up for hypermetropia, no other abnormalities were identified. A sibling history of spina bifida prompted a more detailed evaluation, which returned normal results. This case highlights the importance of recognizing anterior cervical hypertrichosis as a rare but distinct clinical entity. Recognition of this benign entity is important to guide appropriate evaluation, avoid excessive investigations, and reduce caregiver anxiety.
