Incidental invasive thymoma during coronary artery bypass surgery.

We encountered 2 incidental cases of invasive thymomas at Jordan University Hospital, Amman, Jordan; during routine coronary artery bypass graft surgery between 2005 and 2008 with an incidence of 0.6%. Both patients presented with angina pain. None of the 2 patients had pressure symptoms (cough, shortness of breath or superior vena cava syndrome) or Myasthenia Gravis symptoms. Total thymectomy with dissection of perithymic fat was performed on both cases. No radiotherapy was given. No recurrence of the tumor was seen in 2 years follow up. These cases are presented to emphasize the occurrence of this tumor.
