Three children with subcutaneous masses were found to have extramediastinal bronchogenic cysts. The suprasternal area is by far the most common location of this highly unusual embryonic rest cyst. In one of our patients a cyst was located in the scapular region, which is a particularly rare site. To date only 41 subcutaneous bronchogenic cysts have been reported. Preoperative diagnosis is difficult, although the presence of clear mucoid material within the cyst may suggest the diagnosis. The histologic presence of ciliated, pseudostratified, columnar or cuboidal epithelium, mucus-secreting glands, smooth muscles, and occasional cartilage establishes the diagnosis.
三名患有皮下肿块的儿童被发现患有纵隔外支气管囊肿。胸骨上区是这种极不寻常的胚胎残余囊肿最常见的位置。在我们的一名患者中，囊肿位于肩胛区，这是一个极为罕见的部位。迄今为止，仅报道过41例皮下支气管囊肿。术前诊断困难，尽管囊肿内存在清亮的黏液样物质可能提示诊断。囊肿内存在纤毛、假复层、柱状或立方上皮、黏液分泌腺、平滑肌以及偶尔的软骨可确诊。
