clear cells with nuclear atypia.  No further idea.  I would submit the entire specimen, look for mitoses or abnormal mitoses, any focal differentiation.  Call the doc to see if patient has malignancy anywhere else (metastatic clear cell tumor?).  And of course, never forget our friend in modern pathology: immunostains!  Wait to see the results.  Thanks.

 

 好难.猜吧:

首先考虑转移性恶性肿瘤.图片2隐约好象有色素,请排除恶黑.

瘤细胞胞浆透明,因此,肝细胞癌,肌上皮癌,肾细胞癌等胞浆透明的肿瘤都要考虑.建议免疫组化应该有所帮助.

 首先考虑涎腺来源的恶性肿瘤，需说没有肌上皮癌常见的巢状排列，但透明细胞＋间质胶原，首先应该排除肌上皮癌。
