| 以下是引用xiaoxiaolan2495在2010-5-11 18:00:00的发言： cqzhao老师是什么意思啊，是同意平滑肌肉瘤还是多形性肉瘤还是化生性癌呢？ |
I cannot make dx without reading the true slides.
Calponin and actin show weak and diffuse positivity and desmin is negative. It may be a high grade leiomyosarcoma.
If the smoother muscle stins are not reliable, undeferential 肉瘤 is favored.
I did not see any cytokeratin positive, I will not call 化生性癌
