Familial Isolated Accessory Tragi

Abstract

Accessory tragi are an unusual congenital disorder, which are derived from a developmental abnormality of the first branchial arch. They appear at birth as soft or firm skin-colored papules or nodules, usually located in front of the auricle. There was no report of familial accessory tragi in Korean literature. Herein, we present two cases of familial accessory tragi occurring in a brother and a sister.
