The intrathyroidal thymic carcinoma is a rare neoplasm. The probable origin of this neoplasm is the presence of ectopic thymic tissue or remnants of the third and fourth branchial arch. The case of a 49-year-old female with an initial diagnosis of medullary thyroid cancer is presented. When she was operated for regional recurrence, 16 years later, the pathology report demonstrates the presence of a intrathyroidal thymic carcinoma. Intrathyroidal thymic carcinoma is considered an independent type of thyroid carcinoma because this entity has specific clinical-pathological characteristics similar to thymic carcinomas and different prognosis than known thyroid carcinomas. We present the case of a patient initially treated as having a medullary thyroid carcinoma who, upon presenting recurrence, the presence of intrathyroidal thymic carcinoma was demonstrated.
甲状腺内胸腺癌是一种罕见的肿瘤。该肿瘤可能起源于异位胸腺组织或第三、第四鳃弓的残余组织。本文报告了一例49岁女性患者，最初诊断为甲状腺髓样癌。16年后，当她因局部复发接受手术时，病理报告显示存在甲状腺内胸腺癌。甲状腺内胸腺癌被认为是一种独立的甲状腺癌类型，因为该实体具有与胸腺癌相似的特定临床病理特征，且预后与已知的甲状腺癌不同。我们报告了一例最初被诊断为甲状腺髓样癌的患者，复发时证实存在甲状腺内胸腺癌。
