It is difficult to make dx for some endometrial biopsy case. It is no way to make pathologic diagnosis in true practice by only few photos and but not the true sldes. Figures demonstrate irregular and branching glands with paillary pattern and with mild cytologic atypia. No stromal component is noted. This make the evaluation more difficult, confluent growth pattern or surface detached framents. The differential dx include papillary surface syncytial change to endometrioid carcinoma. I favor atypical complex hyperplasia. You need figure out the size the lesion et al. Anyway It is just for your reference.

子宫内膜标本本身就很难做出诊断。在实际工作中，仅凭几幅图像而不实际看切片，几乎没办法做出病理诊断。本例中，腺体不规则、分枝状，细胞轻度异常。未见间质成分，使诊断更为难，是腺体融合生长或分离的片但。据此可以做出鉴别诊断的范围可以从表面乳头状合体细胞增生直到子宫内膜癌。我个人还是倾向于复杂性不典型增生。你需要知道病变范围大小等。仅供参考吧。
