Bilateral cervical accessory tragus: a rare pediatric neck mas

An accessory tragus is a small elevation of skin that contains a bar of elastic cartilage and is usually found along an imaginary line drawn from the tragus to the angle of the mouth or, uncommonly, along the anterior margin of the sternocleidomastoid muscle. These malformations are present at birth. It is usually located unilaterally in the preauricular region. Accessory tragi may occur along the migratory line, as the auricle ascends from the neck area and their origin is the mandibular branchial arch. Other auricular abnormalities are not usually associated with accessory tragus, since the majority of the external ear evolves from the second branchial arch. To the best of our knowledge this is the first accessory tragus case that seen on the lateral cervical region bilaterally.
