We report three cases of neck accessory tragus, which is the largest number of cases with dermatologists reported in China. Neck accessory tragus belongs to special accessory auricular anomaly. Case 1: A 5-year-old girl presented with a skin-colored mass above her right clavicle since birth. Physical examination revealed a pea-sized mass positioned above the right clavicle. Case 2 and case 3 were a 3-month-old female infant and a 4-month-old male infant, respectively. Both of their parents complained that the masses gradually increased in front of the neck. Histopathologically, all of the three cases showed cartilage beneath the subcutaneous tissue. All cases were diagnosed as cervical auricles.
