Objective:
To report a very rare case of incidentally discovered Medullary Thyroid Carcinoma after total thyroidectomy in a patient with Graves' disease, review available literature, and present readers with management information.
Results:
Medullary Thyroid Carcinoma in the setting of Graves' disease is a rare scenario. Only fifteen total cases besides ours has been described in literature, and only six other cases were incidentally discovered.
Conclusions:
When Medullary Thyroid Carcinoma is incidentally discovered in the setting of Graves' disease, retroactive workup should begin with postoperative calcitonin, CEA level, testing for RET mutation, and a comprehensive neck ultrasound as soon as the diagnosis is made.
