Context Bronchogenic cysts are rare congenital malformations of the embryonic foregut, typically located in the mediastinum. This report presents three pediatric cases of subcutaneous bronchogenic cysts in atypical locations—the sternal manubrium, middle cervical region, and scapular area—contributing to the literature by highlighting the anatomical variability of these lesions and the challenges associated with preoperative etiological diagnosis. Case Reports The patients presented with subcutaneous masses exhibiting nonspecific clinical features, such as intermittent drainage, cutaneous appendages, and localized tenderness. Initial clinical impressions suggested alternative etiologies, including branchial remnants or dermoid/sebaceous cysts. In all three cases, definitive diagnosis was established through histopathological examination, which revealed pseudostratified ciliated columnar epithelium consistent with bronchogenic cysts. Surgical management involved complete excision of the lesions, with favorable postoperative outcomes and no recurrence. Conclusion Bronchogenic cysts may present in uncommon subcutaneous locations, complicating preoperative etiological diagnosis. Complete surgical excision is curative and prevents potential complications. These cases underscore the importance of including bronchogenic cysts in the differential diagnosis of pediatric cervical and subcutaneous masses, even when located in atypical regions.
