Synchronous tumours of the thymus and lung are rare. We describe the case of a 57-year-old gentleman, who presented with a large type AB thymoma in the superior anterior mediastinum and a primary bronchogenic adenocarcinoma in the right upper lobe. In view of this, he underwent surgical resection of the thymoma directly through amedian sternotomy and right upper lobectomy via the median sternotomy with video assisted thoracoscopic guidance.
