Revealing the Rare: Unraveling the Enigma of a Branchial Cleft Fistula’s Unusual Journey
摘要
Unveiling an unusual case of a branchial cleft fistula in an atypical location sheds light on the complexities of diagnosing and managing congenital anomalies of the head and neck. An 18-year-old male presented with a longstanding history of a mucinous discharge from an opening below the left jaw, initially misinterpreted as a neck abscess, leading to a misguided incision and drainage procedure. Imaging studies revealed a fistulous tract extending from the left submandibular region to the floor of the mouth. Surgical exploration uncovered an intraglandular tract with a stone-obstructed internal opening. Histological analysis confirmed a first branchial cleft anomaly, though with an uncommon trajectory. This case underscores the necessity for a comprehensive understanding of embryological development and meticulous evaluation in diagnosing branchial anomalies, especially when presentations deviate from typical patterns.
