ABSTRACT
First branchial cleft cyst (FBCC) is a rare entity of congenital anomalies in the head and neck area. Dealing with FBCC is a clinical challenge as the condition is frequently forgotten in the differential diagnosis of lateral neck swelling. We report a rare case of unilateral type I FBCC in an 11-year-old boy who presented with a painless and slow-growing preauricular mass masquerading as a benign cystic lesion of the parotid. The lesion was completely removed via surgical excision. Histopathology report confirmed the findings of squamous epitheliumlined cyst wall, which was a characteristic of a branchial cleft cyst. The combination of good clinical acumen, with the help of radiological correlation, along with a strong degree of suspicion for the condition, facilitates the diagnosis of this condition and hence proper management.
