Benign lung and trachea tumors account for only a small percentage of a bronchologist's and a histopathologist's everyday practice.


The authors describe the clinicopathological features some of these tumors because they may be confused with malignant conditions. To avoid misdiagnosis of malignancy the knowledge of bronchologic and histologic appearance of these tumors is important.


In the past three years 1453 cases were examined and 14 cases of benign tumors were diagnosed, which is 1% of the total number of biopsies and 2.68% of the tumor cases. The diagnoses were: granular cell tumor (Abrokosoff's tumor), neurilemmoma, hemangioma, endobronchial hamartoma, and papillary adenoma. Two of the reported tumors: granular cell tumor and papillary adenoma appeared in the trachea. Tracheal granular cell tumor and bronchial hemangioma were incidental findings beside bronchial carcinoma.


To our best knowledge this is the fifth reported case of the coexistence of Abrikossoff's tumor with bronchial carcinoma.
