[Sialadenoma papilliferum--a rare benign endobronchial tumor].
HISTORY AND PRESENTATION AT ADMISSION: An 82-year-old male patient presented with a 3 week history of exercise-induced dyspnea, productive cough and left sided chest pain.


METHODS
Computertomography of the chest revealed an occluding endobronchial tumor in the left main bronchus with enlarged mediastinal lymph nodes, mediastinal shift and post-stenotic peribronchitis.


METHODS
The tumor was removed completely with an optical forceps in rigid bronchoscopy. Histologically an endobronchial sialadenoma papilliferum was diagnosed.


CONCLUSIONS
Benign tumors of the lower airways are rare. They cannot be distinguished reliably from malignant tumors by their endoscopic and radiologic appearance. Sialadenoma papilliferum is an extremely rare benign salivary gland tumor which is characterized by coexisting glandular and (pseudo) papillar formations. It occurs mainly in the oral cavity. The relapse rate is 10-15%. In single cases a malignant transformation may appear.
