抄録

子宮筋肉腫は、予後不良に関連する侵攻性腫瘍である。これらの新生物は転移の可能性が高く、肺、肝臓、および腹膜に影響を及ぼすことが多い。甲状腺への転移の症例は文献に記載されているものは非常に少ない。我々は47歳女性の子宮筋肉腫が甲状腺に転移した症例を紹介する。この症例報告では、細胞学的評価だけでは困難な場合があるため、付属検査の有用性を強調して、子宮筋肉腫と未分化甲状腺癌の鑑別に役立てたい。

Uterine leiomyosarcomas are aggressive tumors associated with a poor prognosis. These neoplasms have high metastatic potential, more frequently affecting the lungs, liver, and peritoneum. There are very few cases of metastasis to the thyroid described in the literature. We present the case of a 47-year-old female diagnosed with uterine leiomyosarcoma metastatic to the thyroid gland. In this case report, we want to emphasize the utility of ancillary studies to help differentiate a leiomyosarcoma from anaplastic thyroid carcinoma since cytologic evaluation alone can be challenging.
