Abstract
We present a case of papillary thyroid carcinoma developed 12 years after liver transplantation from a brain-dead donor.
A 49-year-old man who had undergone liver transplantation from a brain-dead donor for familial amyloid polyneuropathy at an overseas hospital 12 years earlier had been followed in a Japanese hospital while he was given an immunosuppressant. Ultrasonography of the carotid artery received at a brain dock incidentally detected a thyroid tumor. As a result of close examinations in our hospital, papillary thyroid carcinoma was diagnosed. Left thyroid lobectomy and isthmectomy were performed with left D2a dissection.
It is believed that the use of immunosuppressant after organ transplantation may result in an increase in incidence of having malignant tumors. Further increase in the number of long-term survivors due to improving outcomes of organ transplantation might increase the number of patients who experience malignant disease after the transplantation.
