Paraesophageal bronchogenic cyst is a rare disease. Only 24 cases have been previously reported in Japan. Recently, we experienced two successful cases of this disease. ⋯ Microscopic examination showed the typical findings of the bronchogenic cyst, as the inner wall of the cyst was covered with ciliated columnar epithelium and the wall consisted of cartilage, mucous glands and smooth muscle. Both postoperative courses were uneventful. Resection was recommended because of the symptoms due to the compression of the cyst and the possibility of malignancy.
