Description
Summary:Thymoma with endobronchial polypoid growth is extremely rare, and only 21 cases have thus far been reported, with most of the cases involving obstruction of the left upper bronchus. Furthermore, an endobronchial lesion as a form of distal metastasis is extremely rare, and only 2 cases have been documented. Herein, we report an exceedingly rare case of anterior mediastinal thymoma with remote endobronchial metastasis involving the left lower bronchi without contiguous pleural dissemination. This case appears to be evidence against the previously proposed mechanism-that endobronchial metastatic thymoma spreads through pleural involvement.
