To the Editor: In our review of cases of thymoma,1 we discovered several patients with multiple neoplasms. These patients were not necessarily treated with radiation therapy or found to have a history of myasthenia gravis, suggesting that the association between thymoma and cancer may be intrinsic and not due to treatment or thymoma-associated conditions.
