Esophageal bronchogenic cysts are rare, and since a limited number of cases has been reported, the treatment plan for asymptomatic patients is difficult. A 55-year-old man without any symptoms visited our hospital for further examination of an esophageal mass detected on simple computed tomography. Upper endoscopy showed the protruding, submucosal mass covered by normal mucosa, and endoscopic sonography confirmed hypoechoic lesions originating from the muscularis propria. The patient was diagnosed as having an esophageal duplication cyst and underwent thoracoscopic resection. Pathological findings were consistent with an esophageal bronchogenic cyst. The patient was discharged without any problems on the 6th postoperative day. Upper endoscopy was performed 6 months after surgery, and no evidence of esophageal diverticula or narrowing was present. In conclusion, early thoracoscopic resection of esophageal bronchogenic cysts, before appearance of the symptom, can be a considerable treatment option because it is less invasive and may be advantageous for obtaining a definitive diagnosis in patients who are candidates for safe surgical resection.
