感谢Dr.dujun0522分享这样有趣的病例和漂亮的图片。同时也看到以上精彩的评析。 My thought: 我的想法: 1. Invasive cervical cancer 浸润性宫颈癌 2. Photos show mainly squamous component with focal keratinization and focally glandular component. 图片所示主要为鳞状细胞成分并局灶细胞角化,以及局灶腺上皮成分。 3. Morphologic features are not like classic ACC except for one small tumor nest, not like classic basaloid squamous cell ca 形态学特点中除了一个小细胞肿瘤巢团之外并不像典型的腺样囊性癌Adenoid cystic carcinoma (ACC),也不是很像典型的基底细胞样鳞癌。 4. Stroma change may be caused by treatment. 5. Make things simple and common things are more common. Also clinical treatment will not have much difference. So I would like to call adenosquamous cell carcinoma. 6. All cervical squamous cell ca, adenosquamous cell ca, and most cervical adenocarcinoma ca are HPV related. 7. Clinically sometimes more stains can cause more trouble becasue the result can be difficult to explain. for your reference |
注意到楼主的免疫组化包括许多肌上皮标记和CD117,是否为腺样囊性癌?它比宫颈鳞癌的侵袭性更强。

P63在两批图片中显示弥漫阳性。应该还是鳞癌。 至于为什么会在局部或灶性表达CK8和calponin,只能从两方面解释。一方面可能本身就是基底样鳞癌,基底样癌细胞化疗后残留并增殖的干细胞样特征的基底细胞,可能会表达多潜能细胞标志物、另一方面,可能是由于化疗药物毒性杀伤作用,将一定程度“分化”的鳞癌细胞杀死,而残留下来的是具有耐药机制的癌干细胞(在鳞癌,基底样干细胞)样癌细胞增殖,也可能是未知的机制,经化疗药物作用后,残留的癌细胞改变了普通类型的鳞癌的分化方向,向鳞状上皮的干/祖细胞——基底样细胞去分化,成为基底样表型的鳞癌。 P16强阳性提示高危HPV致癌机制,提示高危HPV基因与宿主宫颈上皮(鳞与腺)基因组整合,是宫颈癌及其前驱病变的重要标志物,还说明这个癌在多数情况下是在宫颈发生的。 以上难免谬论,仅供参考。 |
