谢谢赵老师！

我考虑低分化腺癌，将上传细胞块，请您多指导！

 上传细胞块切片，请各位老师指导，谢谢！（抱歉，切片质量有点差）

 The quality of the slides are not very good. What stain is this? Is it quick H&E? If that is the case, I strongly discourage this type of stain. I basically agree with Dr. Zhao, this is non-small cell carcinoma. If this tumor is surgeically removable, I usually do not bother to do immunostains to further classify. If it is not resectable, because there is treatment differences between squamous cell ca and adenocarcinoma, I will do immunostains to help me further classify. This case I favor an adenocarcinoma on the cell block. One more comment, I have looked at some pictures people posted on this websites, the quality of the slides is not good, that is one of the main reasons to hinder the diagnosis.
