Struma ovarii is a rare specific ovarian tumor. It is a highly differentiated monodermal teratoma with a malignant transformation rate as low as 5%. Thus, malignant transformation and metastasis are extremely rare. The clinical manifestations of this disease are not typical and are easily misdiagnosed.
A 55-year-old female patient had a history of pain in the right hepatic region for approximately 1 year. Computed tomography and magnetic resonance imaging showed a solid cystic mass in the right adnexal region and a solid mass in the right retroperitoneum. The patient underwent surgical resection, and the combined morphological and immunohistochemical results led to the final diagnosis of right struma ovarii with papillary carcinoma and right retroperitoneal lymph node metastasis.
Malignant struma ovarii with distant metastasis is extremely rare, and the clinical manifestations of this disease are nonspecific. Accurate preoperative diagnoses are difficult to obtain, and pathological examination is the gold standard for diagnosing this disease.
卵巢甲状腺肿是一种罕见的特殊卵巢肿瘤。它是一种高度分化的单胚层畸胎瘤，恶变率低至5%。因此，恶变和转移极为罕见。该病临床表现不典型，易被误诊。
一名55岁女性患者有右肝区疼痛病史约1年。计算机断层扫描和磁共振成像显示右附件区有一实性囊性肿块，右腹膜后有一实性肿块。患者接受了手术切除，综合形态学和免疫组化结果最终诊断为右侧卵巢甲状腺肿伴乳头状癌及右腹膜后淋巴结转移。
伴有远处转移的恶性卵巢甲状腺肿极为罕见，该病临床表现无特异性。术前难以获得准确诊断，病理检查是诊断该病的金标准。
