METHODS: A 53-year-old man presented with a right-sided neck mass. Ultrasound showed a well-defined nodule in the right mid third with microcalcification and increased nodular vascularity associated with multiple right-sided cervical lymphadenopathy. The histopathological examination showed multifocal medullary carcinoma with incidental finding of unifocal papillary microcarcinoma conventional type on the left side. Additional pathology of Hashimoto thyroiditis with a small intra-thyroidal parathyroid gland in the left thyroid gland. The procedure went perfectly and the patient was discharged home without any difficulties.
CONCLUSIONS: Synchronous existence of these two neoplasms can occur in two forms: distinct medullary carcinoma and papillary carcinoma isolated by normal thyroid tissue, or mixed medullary and follicular-derived thyroid carcinoma, in which single or multiple lesions show morphology and immunoreactivity for both medullary carcinoma and follicular-derived carcinoma.
CONCLUSIONS: The synchronous coexistence of papillary microcarcinoma, medullary carcinoma, and Hashimoto\'s thyroiditis is an uncommon thyroid condition.
方法:一名53岁男子出现右侧颈部肿块。超声检查显示右侧中部有明确的结节,伴有微钙化和与多个右侧颈部淋巴结肿大相关的结节状血管增加。组织病理学检查显示多灶性髓样癌,左侧偶然发现单灶性乳头状微癌常规型。桥本甲状腺炎的其他病理,左侧甲状腺中的甲状腺甲状旁腺小。手术进行得很顺利,病人出院了,没有任何困难。
结论:这两种肿瘤可以两种形式同时存在:不同的髓样癌和正常甲状腺组织分离的乳头状癌,或者混合髓样和滤泡源性甲状腺癌,其中单个或多个病变显示髓样癌和滤泡源性癌的形态和免疫反应性。
结论:乳头状微小癌同步共存,髓样癌,桥本甲状腺炎是一种罕见的甲状腺疾病。
