以下是引用cqzhao在2010-1-10 22:02:00的发言: Interesting case. Thank for showing complete stains and your final diagnosis. Most adenomyoepitheliomas (AME) are varants of introductal papilloma and small cases may arise from a lobular proliferaton or adenosis. Almost all AMEs are benign and treated with complete local excision. malignant transformation or cases with distant metastases have been described, but they are rare. The maliganancy may be limited to either epithelial or myoepithelial component or both. Evidence of malignancy includes mitotic activity, marked atypia, necrosis, invasive edges. Above case is a difficult one. It may be AME by reviewing photos again. I am not sure the meaning of neuroinvasion. Neuroinvasion may be one of features of malignant tranformation in AMEs. I did not notice in literature. It may be a good case report especially if you have several years of follow up results. 非常感谢 Dr. Zhao 对此病例的点评。乳腺腺肌上皮肿瘤比较少见,有时生物学行为难以判断,许多问题有待研究。建议Dr. Zhao组织一个专题讨论,有兴趣的同道共同参与,提供病例。充分利用我国病例多的优势,在乳腺病理的某些方面有所建树。像日本和欧洲医生那样, 也能在世界外科病理领域争得一些话语权! 问题: 1)您建议的随访是个非常重要的判别肿瘤性质的证据。但是,如果局部癌变组织已经被完全切除,不可能再转移,5年后病人无转移,情况良好,能否定恶性诊断吗? 2)本例浸润神经的肿瘤细胞p53+是否对判断良恶性也有帮助? 谢谢! |
