对 2 1例子宫内膜癌进行超微结构观察。其中子宫内膜腺癌 16例 ,子宫内膜乳头状癌 2例 ,透明细胞癌 2例 ,鳞腺癌 1例。子宫内膜腺癌以形成腺腔及微绒毛为特征 ,随着肿瘤分化程度的降低 ,癌细胞异型性增加 ,并出现篮网状核仁。子宫内膜乳头状癌见分支管道状腔及纤毛细胞。透明细胞癌的形态学特点是细胞浆内多量糖原聚集。研究显示 ,子宫内膜癌的主要形态学特征是腺腔形成 ,同时因保留了其来源于苗勒氏管上皮多方向分化的潜能而分化出纤毛细胞、粘液细胞及鳞状上皮细胞 ,进而形成不同组织学类型的子宫内膜癌。
Ultrastructural observation of 21 cases of endometrial cancer. Among them, 16 cases of endometrial adenocarcinoma, 2 cases of endometrial papillary carcinoma, 2 cases of clear cell carcinoma and 1 case of squamous carcinoma. Endometrial adenocarcinoma is characterized by the formation of glandular lumen and microvilli. As the degree of tumor differentiation decreases, the atypia of cancer cells increases, and the reticular nucleoli appear. Endometrial papillary carcinoma see branch ductal cavity and ciliated cells. The morphological feature of clear cell carcinoma is the accumulation of large amounts of glycogen in the cytoplasm. Studies have shown that the main morphological characteristics of endometrial cancer is the formation of glandular cavity, and at the same time, the ciliated cells, mucous cells and squamous epithelial cells are differentiated due to the potential of multi-directional differentiation from Müllerian epithelium, Endometrial cancer of different histological types.
