title: Hürthle cell thyroid carcinoma metastatic to the sigmoid colon.
abstract: Prognosis of differentiated thyroid cancer is favorable in the majority of cases. However, distant metastases occur in 10-15% of cases, predominantly in lungs and bones, especially in older patients exhibiting poorly differentiated forms or advanced stages. We report a case history of Hürthle cell thyroid carcinoma metastasized to the sigmoid colon. To the best of our knowledge, this location has never been described before. This case history illustrates the difficulties of diagnosis and treatment in patients whose metastases do not concentrate radioiodine. The interest of different imaging modalities, including fluoro-deoxy-glucose positron emission tomography scan and somatostatin receptor scintigraphy, is discussed.
