First branchial cleft anomaly presenting as recurrent postauricular cyst

First branchial cleft anomalies are a special group of congenital malformations that represent <10% of all branchial cleft anomalies. They may present as cysts, swellings, or fistulas in the periauricular region or in the lateral aspect of the neck. Failure to identify these lesions can lead to delay in the diagnosis, often misdiagnosis, inadequate treatment, and subsequent recurrence. We report a case of 15-year-old girl who presented with recurrent postauricular cyst. Fine-needle aspiration biopsy was performed, and it was diagnosed as infected cystic lesion. On histopathological examination, the diagnosis was confirmed as first branchial cleft cyst.
