卵黄囊瘤（内胚窦瘤）是一种恶性生殖细胞肿瘤，通常发生在性腺。性腺外生殖细胞肿瘤是罕见的，并已在病例报告中描述。我们报告一个1岁男孩的单纯肾内卵黄囊肿瘤，他因腹部巨大肿块而被怀疑是肾母细胞瘤而接受手术。肿瘤的组织病理学和免疫组化特征与性腺起源的内胚窦瘤相同。本报告的目的是增加一个罕见的肿瘤的鉴别诊断小儿肾肿瘤。
Yolk sac tumor (endodermal sinus tumor) is a malignant germ cell tumor that usually arises in the gonads. Extragonadal germ cell tumors are rare and have been described in case reports. We report a pure intrarenal yolk sac tumor in a 1-year-old boy who presented with a huge abdominal mass and was operated for suspected Wilms tumor. The tumor exhibited histopathologic and immunohistochemical features identical to those of an endodermal sinus tumor of gonadal origin. The purpose of this report is to add a rare tumor to the differential diagnosis of pediatric renal neoplasms.
