An unexpected cyst of the ear lobule.

Branchial cleft anomalies (BCA) are among the most common congenital anomalies found in the pediatric head and neck. The embryology of these congenital anomalies is well understood, which allows clinicians to anticipate their diagnosis when a pediatric patient presents with a head or neck mass. The predictable anatomy of the various types of BCA allows for improved surgical planning to prevent recurrence and ensure complete resection. This report details an unusual location of a first BCA located in the ear lobule of a 10-month old male. There has been no documented first BCA at the ear lobule in the literature.
