Ectopic thyroid tissue is a result of abnormal embryologic development and migration of the thyroid gland. It has a prevalence of one per 100,000-300,000, and the risk of malignant transformation in ectopic thyroid tissue is rare. We present a rare case of perivesical ectopic papillary thyroid carcinoma in a 76-year-old man with a normal orthotopic thyroid gland. A total thyroidectomy was performed, and the pathology report showed normal thyroid tissue with no neoplastic involvement. The patient was treated with radioactive iodine, and a control scintigraphy was without any signs of activity.
异位甲状腺组织是甲状腺胚胎发育和迁移异常的结果。其患病率为十万分之一至三十万分之一，异位甲状腺组织发生恶性转化的风险罕见。我们报告一例76岁男性膀胱周围异位乳头状甲状腺癌的罕见病例，其原位甲状腺正常。患者接受了甲状腺全切术，病理报告显示甲状腺组织正常，无肿瘤累及。患者接受了放射性碘治疗，对照闪烁扫描未发现任何活性迹象。
