描述: | |
宫颈肥大,3度糜烂,宫颈横径4.2cm。
免疫组化结果:CEA阴性(两次均阴性),ER少数腺体阴性,ki67极少数腺体阳性率30-40%。浸润深度8-10mm,患者无显著的阴道大量排液。
腺体分布散乱,而且位置深在。腺上皮分化良好。应该就是微偏腺癌。
根据图片似微小偏离型腺癌。最好能确认下深度和患者有无阴道大量排液。微小偏离型腺癌PAX2不表达,或呈弱而局灶的表达(PMID:20061933);微小偏离型腺癌分化较差区域常表现为胞浆IMP3和CEA(21497449)阳性有助于鉴别诊断和确诊.
Minimal deviation adenocarcinoma of cervix
Gross: barrel-shaped cervix (diffusely enlarged)
Micro:
l very well differentiated glands (usually endocervical-type) with cystic dilation;
l glands are variable in shape or size with irregular or claw-shaped outlines;
l malignant due to distorted glands with irregular outlines deep in cervix, focal stromal response;
l 50% have small foci with a moderate/poorly differentiated focus;
l often has cilia or apical snouts;
l often has mitotic figures;
Positive stains:
periglandular smooth muscle actin+ stroma (Histopathology 2005;46:130), CEA (variable)
DD:
l diffuse laminar endocervical glandular hyperplasia endocervical type adenomyoma,
l florid deep glands (bland inactive appearing cells),
l lobular endocervical glandular hyperplasia (noninvasive proliferation of endocervical glandular cells in lobular arrangement without any irregular stromal infiltration, desmoplasia or focal malignant features, Pathol Int 2005;55:412, AJSP 1999;23:886),
l microglandular hyperplasia (different morphology; CEA negative),
l pseudoinfiltrative tubal metaplasia of the endocervix associated with in utero DES exposure (Int J Gynecol Pathol 2005;24:391),
这个病例齐鲁医院会诊没能确诊,发的高度可疑。因为两次免疫组化CEA均阴性,Ki67极少数腺体阳性率30-40%。请继续讨论。
Most cases are positive for CEA. But negative CEA is not the reason to exclude the diagnosis. The dx is mainly based on the morphology
好病例,学习了!!!
文献资料有报道微偏腺癌病例在宫颈刮片中找到癌细胞,但在印象中,微偏腺癌细胞一般分化都比较好,请教下各位老师,其脱落细胞学有没有特征性的改变,怎样在宫颈刮片中更好地认识它
宫颈细胞学没法确诊。

我认为细胞学诊断微偏腺癌是个盲区
In fact Pap test is not desiged for cervical adenocarcinoma
