答案是: 超常胎盘反应 exaggerated placental site
The last picture shows a double staining for HLA-G/ki67. HLA-G labels trophoblastic cells. From the double staining, we can see that the trophoblasts are positive for HLA-G but negative for ki67. Ki67 only labels the background lymphocytes.
最后一幅图是HLA-G和KI67的双标记, HLA_G标记滋养细胞, 但是滋养细胞并没有标记KI67. 图中KI67标记的是淋巴细胞, 不是滋养细胞. 在这儿滋养细胞.虽然看起来有点atypical ,但是没有分裂相,KI67是零, .
鉴别诊断: PSTT(placental site trophoblastic tumor) , KI67一般>10%.
