1976年 Kurman 等描述了一种变异的滋养细胞疾病并称之为滋养细胞假瘤。在形态学上细胞类似滋养细胞并且侵入周围组织。对这些侵入的细胞进行免疫酶学研究提示存在有绒毛膜促性腺激素(hcG)。本病也有一些特点不同于绒癌。该肿瘤缺少通常如绒癌那样同时具有细胞滋养细胞及合体滋养细胞的两种细胞类型,在瘤体中亦无广泛坏死及出血。细胞浸润的特点是细胞潜入肌束及纤维束之间。在12例此种患者中,无因本病而
In 1976 Kurman et al. Described a variant of the trophoblastic disease and called trophoblastic pseudotumor. Morphologically, cells resemble trophoblasts and invade surrounding tissues. Immuno-enzymatic studies of these invading cells suggest the presence of human chorionic gonadotropin (hcG). The disease also has some characteristics different from choriocarcinoma. The tumor lacks both cell types, which typically have both cytotrophoblasts and syncytiotrophoblasts, as in choriocarcinoma, and without extensive necrosis and bleeding in the tumor. Cell infiltration is characterized by the cells diving into the muscle bundle and between the fiber bundles. In 12 cases of such patients, no due to the disease
