Background. Surgical resection is the preferred treatment for patients presenting with localized bronchial carcinoids. However, no definitive treatment has yet been established for bronchial carcinoids. Case 1. A woman in her 50s was referred to our hospital because of an intraluminal tumor in the right main bronchus on chest computed tomography that was pointed out during a medical checkup. The tumor was resected endoscopically with high-frequency electrosurgical snaring and it was thereafter diagnosed to be a typical carcinoid. No recurrence has so far been seen during a one-year follow-up. Case 2. A man in his 40s was referred to our hospital because of an abnormal shadow on a chest X-ray that was pointed out during a medical checkup. Chest computed tomography showed an intraluminal tumor in the right basal bronchus. Thoracoscopic right lower lobectomy was performed in addition to lymph node dissection (ND2a-1) and the tumor was diagnosed to be an atypical carcinoid. No recurrence has so far been seen during a five-year follow-up. Conclusion. Checking the size, location, tissue type and extension of the tumor is important to select the optimal treatment for bronchial carcinoids.
