Abstract:
Accessory tragus is an embryologic developmental anomaly of the external ear. It is usually presented as congenital, firm papules located anterior to tragus; but rarely, it apprears along an imaginary line drawn between the pretragal and the angle of the mouth, or on the neck along the anterior edge of the sternocleidomastoid muscle and the sternoclavicular region. Histologically, there are numerous follicles, prominent connective tissue framework in the subcutaneous fat and central core of cartilage. The diagnosis is made by the age of onset, site of localization, and affirmative histopathology. We herein report a unique case of cervical accessory tragus on the suprasternoclavicular region in an 8 year-old-boy along with a study of embryological review and differential diagnosis.
