Thymomas are the most common neoplasms of the mediastinum. It is common that thymoma invades
neighboring structures in the thorax, but direct polypoid tumor growth into the airway is
extremely rare. We report a rare case of invasive thymoma with polypoid endobronchial growth
in a 66-year-old woman. Computed tomography demonstrated an anterior mediastinal tumor
which extended into the right upper lobe. Endoscopic examination revealed a polypoid tumor
which occluded the right upper bronchus. A biopsy specimen obtained from the intraluminal mass
was very suggestive of thymoma. The patient had no parathymic syndrome. The tumor was resected
with the right upper lobe. The final post-operative tissue findings confirmed a type B2
thymoma of the World Health Organisation classification.
