作者讨论了在1866年至1975年间50多例母体癌肿累及胎盘及/或胎儿的资料,并按组织学标准重新编组。一、病例整理分类根据胎盘巨检和镜检及病因学和胎儿预后,分为真正的胎盘转移瘤(侵犯绒毛)和绒毛间癌栓子(局限于绒毛间室)两类。又根据母体的原发性肿瘤而分转移为:母体实质瘤,恶性网状淋巴组织病和白血病的胎盘及/或胎儿三种。此外尚有极罕见的来源于胎儿肿瘤转移到胎盘的几例。 (一)实质性瘤转移到胎盘及/或胎儿:32例。 1.真正的胎盘转移瘤:12例(表一) 此组病例的主要病因是恶性黑色素瘤(58％),
The authors discuss data on the placenta and / or fetus involving more than 50 maternal cancers between 1866 and 1975 and are regrouped according to histological criteria. First, the classification of cases based on placental macroscopy and microscopic examination and etiology and fetal prognosis, divided into real placental metastases (violation of villi) and villous cancer emboli (confined to the villi compartment) two categories. And according to the mother’s primary tumor and sub-metastasis as: the mother of solid tumors, malignant reticular lymphoid disease and leukemia in the placenta and / or fetus three. In addition there are very rare cases of fetal tumor metastasis from the placenta in a few cases. (A) Substantial tumor metastasis to the placenta and / or fetus: 32 cases. 1 true placental metastases: 12 cases (Table 1) The main cause of this group of patients is malignant melanoma (58%),
