We herein describe a case of thymoma in which metastasis to the left lower visceral and parietal pleura was noticed after a 2-year dormancy. A closer examination revealed no evidence that the metastatic tumors were of lymph node origin. The initial thymoma was well encapsulated, and thus it was thought that the development of metastasis might have reflected a sudden rapid growth of the thymoma cells after a 2-year period of inactivity.
