We report a case presented with congenital cartilaginous rest of left cheek and clinically bilateral multiple accessory tragi. The concurrence of these congenital anomalies may originate from the 1st or 2nd pharyngeal arch. A 24-year-old woman was noted to have four asymptomatic skin-colored protruding masses over bilateral preauricular area and left cheek since birth. The histopathology of the tumor at left cheek revealed a central core of elastic cartilage with surrounding collagen bundles and adipose tissue in the dermis and subcutis. Vellus hair follicles, sebaceous glands and eccrine glands in the overlying dermis were also noted. A diagnosis of congenital cartilaginous rest of the cheek was made. To our knowledge, concurrence of congenital cartilaginous rest of the cheek and bilateral accessory tragi is very rare.
