腺瘤 |
Agree: adenoma (腺瘤), based on gross description and submitted photos. Debating between monophasic or myoepithelial adenoma. p63 stain will help.
但最好全取材，at least the whole capsule area, to look for possible invasion and/or pleomorphic component.
| 以下是引用mingfuyu在2010-3-31 7:26:00的发言： Not the kind of cases i see everyday. Was about to check books but too busy today. I think it may represent monophasic pleomorphic adenoma/mixed tumor if other areas don't cartilage or other stromal tissues or, as pointed by others, myoepithelial adenoma. Don't favor acinic cell carcinoma. I don't see real mitoses. |
本例并非是常见的病变类型，今天较忙没来得及查书。不过我认为，如果没有明确的软骨、其它间叶组织或其它如肌上皮瘤的形态，则可能是单形性的多形性腺瘤/混合瘤。不支持腺泡细胞癌。没有看到明确的核分裂像。
谢谢mingfuyu老师的意见！

基底细胞腺瘤与对应的基底细胞腺癌有时很难以鉴别。如果是见到核分裂比较活跃，还需要注意细胞的多形性，仔细寻找有无坏死灶。虽然一处图片显示边界清楚，最好还是全取材，看看肿瘤周边有没有侵袭性生长，特别要注意是不是沿着神经和血管生长。
从临床角度，基底细胞腺癌是属于低度恶性肿瘤，腮腺切除后随访，效果还不错。
