[摘要] 通过对1例伴绒毛膜上皮癌分化的子宫内膜未分化癌进行临床、病理及免疫组化观察，结果发现，肿物大小约3.0 cm×2.5 cm，实性，质较硬，镜下肿瘤组织由分化差的上皮样细胞构成，癌细胞核大、异型，实性分布，间质少，可见多核合体细胞，核分裂多见。免疫组化显示瘤细胞CK7(+)、ER(-)、PR(-)、CD68(-)，合体细胞HCG(+)。这是一种罕见的恶性肿瘤，一般预后较差，由于文献报道例数有限，预后的评价尚待进一步统计分析。

[Abstract] One case of endometrioid undifferentiated carcinoma with choriocacinomatous differentiation was observed clinically and pathologically with HE staining and immunohistochemistry. The results showed that, the endometrial neoplasia was about 3.0 cm×2.5 cm. The low-differentiated tumor cells were arranged in solid nets with scant stroma, marked atypically, multinucleated syncytial cells and convoluted nuclei. The tumor cells stained positively for CK7(+), syncytial cells negatively for ER(-), PR(-), CD68(-) positively for HCG(+). Endometrioid undifferentiated carcinoma with choriocacinomatous differentiation is a rare entity with features of higher m alignant tumor, and the prognosis is difficult to be evaluated for rare cases reported.

伴绒毛膜上皮癌分化的子宫内膜未分化癌(简称伴绒癌分化的子宫内膜未分化癌，endometrioid undifferentiated carcinoma with choriocacinomatous differentiation)是一种罕见的子宫内膜恶性肿瘤，国内外文献少有报道，现就我院诊断的1例伴绒癌分化的子宫内膜未分化癌患者，结合文献对其临床病理特点、诊断及鉴别诊断进行研究分析。
