Syndromes which may feature accessory tragus: an overview

Accessory tragus is an easily recognized congenital cutaneous anomaly. There are syndromes, which feature accessory tragi. These are Delleman syndrome, Goldenhar syndrome, Haberland syndrome, and Townes-Brock syndrome. However, these syndromes, which are named eponymously, are also known in the medical literature by other names. The Online Mendelian Inheritance of Man (OMIM), which is well-known data base for genetic diseases and syndromes, also, lists them by different names. Table 1 sheds some lights on these uncommon syndromes.
