Bronchogenic cysts originate from abnormal budding of the tracheal diverticula during the embryological period. Inaccuracy in the process of growing of the ventral foregut will give rise to bronchogenic cyst. Scapular bronchogenic cyst is an extremely rare form of this anomaly. A three years old boy suffered for 2 years with left sided suprascapular cystic lesion which was gradually increasing in size. The swelling was 4 × 3 cm in size and non tender. The cyst was evaluated by CT scan that showed complex cystic lesion over the left scapular spine. Total excision of the cyst was done and histopathology showed cutaneous bronchogenic cyst. The proposed mechanism for such cutaneous lesion is that the accessory buds from the tracheobronchial tree/primitive foregut migrated from the thorax in an aberrant manner to lie in periscapular positions. The definitive treatment of scapular lesions is total surgical excision. The final diagnosis is based on the histopathological findings in the majority of cases.
支气管源性囊肿起源于胚胎期气管憩室的异常芽生。腹侧前肠生长过程中的不准确会导致支气管源性囊肿。肩胛支气管源性囊肿是这种异常的一种极其罕见的形式。一名3岁男孩左侧肩胛上囊性病变已患病2年，且病变大小逐渐增大。肿块大小为4×3厘米，无压痛。通过CT扫描对囊肿进行评估，结果显示左肩胛棘上方有复杂的囊性病变。对囊肿进行了完整切除，组织病理学显示为皮肤支气管源性囊肿。这种皮肤病变的推测机制是，气管支气管树/原始前肠的副芽以异常方式从胸部迁移至肩胛周围位置。肩胛病变的确定性治疗方法是手术完整切除。在大多数情况下，最终诊断基于组织病理学检查结果。
