Management of Congenital Third Branchial Arch Anomalies: About 2 Cases

A rare source of lateral neck masses of congenital origin are branchial abnormalities, which arise from aberrant development during embryogenesis.The most frequent source of origin is the second branchial cleft; anomalies resulting from the first, third and fourth clefts are less common.Even though branchial cleft-derived cysts are rare, it's crucial to take this condition into account when making a differential diagnosis for neck masses, especially those that are laterally situated.This article presents the rare case of a child of 6 years who presented the sudden appearance of a lateral collection in the neck fistulized to the skin with notion of recurrent neck infections at the same site.Patient underwent extensive diagnostic examinations, including radiology, which were consistent with a left subcutaneous collection measuring17.2*15mm with irregular, heterogeneous and hypoechogenic contours.This article presents the rare case of 2 children aged 6 and 7 who presented with the sudden onset of a lateral collection in the neck fistulized to the skin with notion of recurrent neck infections at the same site.The patients underwent extensive diagnostic examinations, including radiology, which were compatible with a left subcutaneous collection measuring a cauterization was performed on both patients.Nine months after surgery, there were no signs of neck infection or purulent episodes.This clinical example underlines how essential it is to identify uncommon diseases such as branchial cleft cysts as early as possible and treat them appropriately.
