Abstract

The increasing risk of subsequent malignancy after treatment of malignant lymphoma is well known, which is mainly due to longer survival of these patients. Radiotherapy at an early stage of Hodgkin's disease or non-Hodgkin's lymphoma is accepted to be associated with future occurrence of secondary thyroid cancer. Nevertheless, the synchronous presentation of these malignancies is extremely rare. Well differentiated thyroid cancer, a slow-growing tumor that responds to therapy with surgery and radioactive iodine, is associated with prolonged survival. therefore, it is important to make this diagnosis in patients who show evidence of malignant lymphoma. Furthermore, appropriate treatment must be considered for thyroid cancer to improve the prognosis of these patients. We herein reported 4 cases of synchronous thyroid cancer and malignant lymphoma in patients who had not previously recieved radiotherapy or chemotherapy.
