1、Giovanna Giordano,…….  Villoglandular adenocarcinoma of the cervix: two new cases with morphological and molecular study. Int J Gynecol Pathol. 2007 Apr;26(2):199-204.

In this paper, we report 2 new cases of villoglandular papillary adenocarcinoma (VGPA) of the cervix, a rare, well-differentiated form of cervical adenocarcinoma. Both patients were without medical complications or history of oral contraceptive use and were nonsmokers. Extended hysterectomy was performed in both cases. Morphological criteria for a correct pathological diagnosis were emphasized. Immunohistochemical analysis was performed to clarify the phenotype of the neoplasms. Moreover, for the first time, we probed to establish if VGPA could be correlated to human papilloma virus (HPV) and herpes virus (HSV) types 1 and 2, using polymerase chain reaction amplification of tumoral DNA. Both neoplasms showed positivity for B72.3, Ca-125, carcinoembryonic antigen, keratin 7, and p16(INK4a) protein. Vimentin, P53, estrogen, and progesterone receptors, instead, were negative. Molecular study by polymerase chain reaction amplification of tumor DNA revealed a strong positive signal for HPV-DNA and no signal for HSV-DNA. It is reasonable to conclude that our cases of VGPA, in accordance with other examples reported in literature, are due to HPV infection. Behavioral cofactors, such as HSV infection (types 1 and 2), oral contraceptive use and smoking, involved in the pathogenesis of other cervical malignancies, can be excluded for the present cases.

作者报道2例绒毛腺型乳头状腺癌（villoglandular papillary adenocarcinoma, VGPA）。2例均无并发症、无口服避孕药史、无吸烟史，均作子宫扩大切除。强调了正确诊断的形态学标准，通过免疫组化检测明确肿瘤的表型，而且，第一次用PCR法检查是否与HPV和HSV1/2有关。2例均呈B72.3、Ca-125、CEA、CK7和p16阳性，VIM、p53、ER、PR均阴性。PCR呈HPV强阳性，HSV阴性。与文献一致，结果提示VGA与HPV有关。其它辅助因素如：HSV、口服避孕药、吸烟等与宫颈其它恶性肿瘤有关者，与此2例无关。

图示：病变特征为指状或分枝状的乳头，有纤维血管轴心。表覆上皮由复层柱状细胞组成。核圆到拉长（卵圆），呈某种程度复层化及轻到中度异型性（A，HE 100）。浸润性成分，特征为乳头状和腺样，伴促纤维形成性的间质反应（B，HE 200）。
