[Two cases of the bronchial cyst located in the anterior mediastinum].

Bronchial cysts are common cystic tumors around the tracheobronchial tree in the middle and posterior mediastinum and rarely locate in the anterior mediastinum. We reported two cases of the bronchial cyst located in the anterior mediastinum. One case was a 57 year-old-female. A thymic cyst was suspected and the extended total thymectomy was performed through the mediansternotomy. The microscopic examination showed bronchial epithelium and cartilage in the cystic wall. The another case was 71 year-old-male operated by thoracoscopic surgery for the cystic tumor in the anterior mediastinum. Microscopic examination showed bronchial epithelium and gland in the cystic wall.
