In Japan, the case of bronchial adenoma has been rare in comparison with other countries.
Recently, two cases of bronchial adenoma were seen. The 1st case was a 46 year-old female with chief complaints of dyspnea and abnormal chest x-ray. The bronchoscopy revealed a tumor in the left main bronchus, and the biopsy showed a cylindroid type of bronchial adenoma. However, the left lobectomy was unsuccessful, because of the metastasis in the lung.
The 2nd case was a 23 year-old male with chief complaints of hemoptysis or bloody sputa for about 5 years. The chest x-ray showed an atelectasis in the right lower lung field, and a tumor was recognized in the right lower bronchus by bronchoscopy and bronchography. The right lobectomy of the middle lobe and the lower lobe was performed, and a carcinoid type of bronchial adenoma was recognized.
After the operations, both cases showed negative in 5-Hydroxyindole acetic acid test in urine.
