同意粘液腺癌，后几张图片砂粒体样结构，没有见过，翻了一下书，“细胞非典型性、核分裂和微钙化不常见，可偶见。”

谢谢

 cqzhao老师的发言：

很可能是个粘液腺癌。当然仅仅凭几幅图片就对整个病例做出评价和诊断是有难度的。就像上面Dr. qianxun所提到的，良性的粘液囊肿之类的病变也应该注意排除。WHO规定粘液性成分超过90%我们就可以称为粘液腺癌。但是有些教材提出此比例为75%即可。事实上我们日常工作中只有粘液性成分达到100%的时候我们才称为粘液腺癌，否则我们就称为导管癌，其中粘液性成分占……。纯粹的粘液腺癌预后良好。

 Mostly it is a mucinous ca. Of casue it is difficult to evaluate the case with only a few photos. As dr. qianxun mentioned above benign mucocele like lesions should be excluded.

WHO: the pure mucinous ca can be called if mucinous component should account for more than 90%. Some book uses the cut-of 75%. In fact in our practice we call pure mucinous ca only for the cases with 100%  mucinous component. Otherwise we will call ductal ca with xxx% municous component. The prognosis of pure mucinous ca is good.

  Everyone is confident.  I am not.  Why not mucocele like lesion?
