A Case of Bronchial Lipoma

Abstract

Bronchial lipoma is a very rare benign tumor of the lung, and only 16 cases have been reported in Japan. Recently, we experienced the following case of the bronchial lipoma. A 62 year-old man was repeatedly suffering from cough, dyspnea and elevation of fever from 1984. Chest radiograph revealed atelectasis of right middle and lower lobes. Bronchoscopic findings showed a tumor obstructing the right main bronchus. The biopsy specimen demonstrated normal epithelium and loose connective tissue, but showing no malignancy. Under the diagnosis of a benign tumor, right middle and lower lobectomy was performed. Histologically, the tumor proved to be a bronchial lipoma.
