Curr Oncol 2023; 30:5738-5768. [PMID: 37366914 DOI: 10.3390/curroncol30060431] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2023] [Revised: 06/05/2023] [Accepted: 06/07/2023] [Indexed: 06/28/2023] Open
Abstract
This guideline provides evidence-based guidance on the risk-based management of cervical dysplasia in the colposcopy setting in the context of primary HPV-based screening and HPV testing in colposcopy. Colposcopy management of special populations is also discussed. The guideline was developed by a working group in collaboration with the Gynecologic Oncology Society of Canada (GOC), Society of Colposcopists of Canada (SCC) and the Canadian Partnership Against Cancer (CPAC). The literature informing these guidelines was obtained through a systematic review of the relevant literature via a multi-step search process led by information specialists. The literature was reviewed up to June 2021 with manual searches of relevant national guidelines and more recent publications. Quality of the evidence and strength of recommendations was assessed using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) framework. The intended users of this guideline include gynecologists, colposcopists, screening programs and healthcare facilities. Implementation of the recommendations is intended to promote equitable and standardized care for all people undergoing colposcopy in Canada. The risk-based approach aims to improve personalized care and reduce over-/under-treatment in colposcopy.

Abstract
PURPOSE To prospectively assess the incremental value of intravoxel incoherent motion (IVIM) DWI in determining whether the adenocarcinoma originated from the uterine corpus or cervix. METHODS Eighty consecutive uterine adenocarcinomas from the cervix or endometrium confirmed by histopathology underwent IVIM DWI acquisition on a 3.0T MR scanner before treatment. Five morphologic features were analyzed using Fisher exact test; IVIM DWI-derived parameters, including apparent diffusion coefficient (ADC), true coefficient diffusivity (D), perfusion-related diffusivity (D*), and perfusion fraction (f) were compared using two-sample independent t-test or Mann-Whitney U test. Logistic regression analysis was used to develop different diagnosis model. The ROCs of these variables and diagnostic models were compared to evaluate the diagnostic efficiency. RESULTS Among single morphologic features, tumor location yielded the highest AUC of 0.891 in distinguishing endometrial adenocarcinoma (EAC) from cervical adenocarcinoma (CAC). Among single IVIM DWI-derived parameters, f values showed the best diagnostic performance (AUC: 0.837) at the optimal cut-off value of 0.261. Additionally, the combined diagnostic model, which consisted of tumor location, ADC and f showed the largest AUC of 0.967 with the highest sensitivity of 88.14%, highest specificity of 100.00%, and highest accuracy of 91.25%. CONCLUSION IVIM DWI-derived parameters add additional diagnostic value to conventional morphologic features. A combined diagnosis model is a promising imaging tool for predicting the origin of uterine adenocarcinoma, further contributing to therapeutic decision-making.

Abstract
Modern classification schemes divide cervical adenocarcinomas into human papillomavirus (HPV)-associated and HPV-independent types. The precursor lesions of the former are well known and comprise HPV-associated (usual/endocervical) adenocarcinoma in situ (AIS) and the much less common stratified mucin-producing intraepithelial lesion (SMILE). The precursor lesions of HPV-independent cervical adenocarcinomas are much less well known, although postulated precursors of gastric-type adenocarcinoma include atypical lobular endocervical glandular hyperplasia and gastric-type AIS. In this review, we cover HPV-associated and HPV-independent precursor lesions of cervical adenocarcinomas concentrating on diagnostic criteria (morphology and immunophenotype) and differential diagnosis. We propose a uniform terminology and diagnostic criteria for precursor lesions showing intestinal differentiation with goblet cells because this may be a feature of both HPV-associated and HPV-independent AIS.

Measurement of tumor size in early cervical cancer: an ever-evolving paradigm. Int J Gynecol Cancer 2020; 30:1215-1223. [DOI: 10.1136/ijgc-2020-001436] [Citation(s) in RCA: 13] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2020] [Revised: 05/25/2020] [Accepted: 06/02/2020] [Indexed: 02/01/2023] Open
Abstract
The major tenets in accurately assessing tumor size in patients with early stage cervical cancer currently include physical examination, imaging studies, and pathologic evaluation. It is estimated that when comparing clinical stage based on physical examination and final pathology, the concordance diminishes as stage increases: 85.4%, 77.4%, 35.3%, and 20.5% for stage IB1, IB2, IIA, and IIB, respectively. Vaginal involvement and larger tumor diameter are considered the main causes of stage inaccuracy. When considering imaging studies, magnetic resonance imaging (MRI) provides the highest level of accuracy in the assessment of cervical tumor size. Its accuracy in determining tumor location within the cervix is approximately 91% and in predicting tumor size 93%. MRI imaging is also significantly more accurate in measuring tumor size, delineating cervical tumor boundaries, and local tumor extension when compared with computed tomography (CT) scan. When comparing with pelvic ultrasound, the accuracy of both imaging techniques (MRI and pelvic ultrasound) in the assessment of tumor size in small versus large tumors is comparable. Pertaining to pathology, the depth of invasion should be measured by convention from the nearest surface epithelium, which equates to tumor thickness. In the setting where tumor is found both in the conization and hysterectomy specimen, the horizontal extent should be measured by summing the maximum horizontal measurement in the different specimens and the depth of invasion measured as the maximum depth in either specimen. A new pattern-based classification for endocervical adenocarcinomas recommends the description of patterns of invasion for human papillomavirus (HPV)-related adenocarcinomas as this is associated with differing risks of lymph node involvement.

The newly proposed International Endocervical Adenocarcinoma Criteria and Classification and its relevance to cervical cytology screening assessed in a prospective 2-year study of 118 cases. Cytopathology 2020; 31:288-291. [PMID: 32289186 DOI: 10.1111/cyt.12831] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2019] [Revised: 03/23/2020] [Accepted: 04/02/2020] [Indexed: 12/22/2022]
Abstract
BACKGROUND It is generally acknowledged that interobserver variability for the histological diagnosis of endocervical adenocarcinoma (EA) subtypes is suboptimal. The recently proposed International Endocervical Adenocarcinoma Criteria and Classification (IECC) system is based on the presence of associated human papilloma virus (HPV) infection. It recognises HPV-associated EAs and non-HPV-associated EAs. METHODS This prospective cytology-histology and molecular genetics-based study investigated the potential effect of IECC being applied to Papanicolaou (Pap) test with regard to the diagnostic accuracy of severe glandular lesions reported at least as adenocarcinoma in situ (AIS). RESULTS Out of 118 liquid-based cytology Pap tests with AIS+ lesion, complete information on follow-up biopsy and HPV status was available in 51 cases. AIS and EA category correlated with histologically confirmed AIS/EA in 88.5% (23/26) and 70.5% (12/17) of cases, respectively. Interestingly, 93% (40/43) of cases diagnosed as AIS/EA were HPV positive and 7% (3/43) were HPV negative (originating in the cervix, endometrium and adnexa). CONCLUSIONS Our findings suggest that this approach could possibly divide Pap tests containing severe glandular lesion into two groups: (a) robust diagnosis of HPV-associated EA and (b) non-HPV associated glandular lesions of heterogeneous origin, requiring further clinical preoperative diagnostic workup.

Abstract
In the 2014 WHO classification, squamous cell precursor lesions are classified as low-grade and high-grade intraepithelial lesions. LSIL corresponds to CIN1, HSIL includes CIN2 and CIN3. Only adenocarcinoma in situ (AIS) is accepted as precursor of adenocarcinoma and includes the stratified mucin-producing intraepithelial lesion (SMILE). Although relatively rare, adenocarcinoma and squamous cell carcinoma can be mixed with a poorly differentiated neuroendocrine carcinoma. Most cervical adenocarcinomas are low grade and of endocervical type. Mucinous carcinomas show marked intra- and extracellular mucin production. Almost all squamous cell carcinomas, the vast majority of adenocarcinomas, and many rare carcinoma types are HPV related. For low grade endocervical adenocarcinomas, the pattern-based classification according to Silva should be reported. Neuroendocrine tumors are rare and are classified into low-grade and high-grade, whereby the term carcinoid is still used.

Architectural overlap between benign endocervix and pattern-A endocervical adenocarcinoma: Are all pattern-A tumors invasive? Pathol Res Pract 2017; 213:799-803.

Abstract
Studies on the pattern-based classification for invasive endocervical adenocarcinoma showed that tumors with nondestructive invasion (pattern-A) have a 0% rate of nodal metastases. Our understanding of pattern-A tumors and their distinction from in-situ adenocarcinoma requires further study. Thirteen sections diagnosed independently as pattern-A adenocarcinoma by three gynecologic pathologists, and 14 sections of benign endocervix were selected. Three additional pathologists (reviewers) evaluated a digital image from each section and classified it as pattern-A or benign based on architecture only. To blind the interpretation to cytologic features, nuclei and cytoplasm were obscured using morphometric software (Zen 2011, Carl Zeiss Microscopy, Germany). 13/27 cases (48%; 8 pattern-A, 5 benign) were correctly classified by all reviewers; 19/27 (70%; 10 pattern-A, 9 benign) were correctly classified by ≥2 reviewers. 3/13 pattern-A cases (23%) were interpreted as benign by ≥2 reviewers. Conversely, 5/14 benign cervices (36%) were misinterpreted as pattern-A by ≥2 reviewers. The number of glands per 20× field was higher in pattern-A cases with high reviewer agreement (p=0.004). An abnormal architecture is seen in many pattern-A adenocarcinomas in support of their invasive nature; some, however, have architecture that overlaps with that of benign endocervix thus may actually represent in-situ lesions. Likewise, normal cervix can be architecturally complex and mirror patterns that pathologists would classify as pattern-A if malignant cytologic features were present. Based on this overlap and the nil risk of nodal spread, an emphasis on the non-destructive, rather than the invasive, nature of pattern-A adenocarcinoma is recommended.

Abstract
A pattern-based classification for invasive endocervical adenocarcinoma has been proposed as predictive of the risk of nodal metastases. We aimed to determine the reproducibility of such classification in the context of common diagnostic challenges: distinction between in situ and invasive adenocarcinoma and depth of invasion measurement. Nine gynecologic pathologists independently reviewed 96 cases of endocervical adenocarcinoma (two slides per case). They diagnosed each case as in situ or invasive carcinoma classifying the latter following the pattern-based classification as pattern A (non-destructive), B (focally destructive) or C (diffusely destructive). Depth of invasion, when applicable, was measured (mm). Overall, diagnostic reproducibility of pattern diagnosis was good (κ=0.65). Perfect agreement (9/9 reviewers) was seen in only 11 cases (11%), all destructively invasive (10 pattern C and 1 pattern B). In all, ≥5/9 reviewer concordance was achieved in 82/96 cases (85%). Distinction between in situ and invasive carcinoma, regardless of the pattern, showed only slight agreement (κ=0.37). Likewise, distinction restricted to in situ versus pattern A was poor (κ=0.23). Distinction between non-destructive (in situ+pattern A) and destructive (patterns B+C) carcinoma showed significantly higher agreement (κ=0.62). Estimation of depth of invasion showed excellent reproducibility (ICC=0.82). However, different measurements resulting in differing FIGO stages were common (from at least 1 reviewer in 79% cases). On the basis of interobserver agreement, the pattern-based classification is best at diagnosing destructive invasion, which carries a risk for nodal metastases. Agreement in diagnosing in situ versus invasive carcinoma, including pattern A, was poor. Given the nil risk of nodal spread in in situ and pattern A lesions, the term 'endocervical adenocarcinoma with non-destructive growth' can be considered when the distinction is difficult, after excluding destructive invasion. Depth of invasion measurement was highly reproducible among pathologists; thus, the pattern-based approach can complement, but should not replace, the depth of invasion metric.

Abstract
PURPOSE To report discriminant MRI features between cervical and endometrial carcinomas and to design an MRI- scoring system, with the potential to predict the origin of uterine cancer (cervix or endometrium) in histologically indeterminate cases. MATERIALS AND METHODS Dedicated pelvic MRIs of 77 patients with uterine tumors involving both cervix and corpus were retrospectively analyzed by two experts in female imaging. Seven MRI tumor characteristics were statistically tested for their discriminant ability for tumor origin compared to final histology: tumor location, perfusion pattern, rim enhancement, depth of myometrial invasion, cervical stromal integrity, intracavitary mass, and retained endometrial secretions. Kappa values were estimated to assess the levels of inter-rater reliability. On the basis of positive likelihood ratio values, an MRI-score was assigned. RESULTS K value was excellent for most of the imaging criteria. Using ROC curve analysis, the estimated optimal cut-off for the MRI-scoring system was 4 with 96.6% sensitivity and 100% specificity. Using a ≥4 cut-off for cervical cancers and <4 for endometrial cancers, 97.4% of the patients were correctly classified. 2/58 patients with cervical cancer had MRI score <4 and none of the patients with endometrial cancer had MRI score >4. The area under curve of the MRI-scoring system was 0.99 (95% CI 0.98-1.00). When the MRI-score was applied to 20/77 patients with indeterminate initial biopsy and to 5/26 surgically treated patients with erroneous pre-op histology, all cases were correctly classified. CONCLUSION The produced MRI-scoring system may be a reliable problem-solving tool for the differential diagnosis of cervical vs. endometrial cancer in cases of equivocal histology.

Abstract
Premalignant lesions of the lower female genital tract encompassing the cervix, vagina and vulva are variably common and many, but by no means all, are related to infection by human papillomavirus (HPV). In this review, pathological aspects of the various premalignant lesions are discussed, mainly concentrating on new developments. The value of ancillary studies, mainly immunohistochemical, is discussed at the appropriate points. In the cervix, the terminology and morphological features of premalignant glandular lesions is covered, as is the distinction between adenocarcinoma in situ (AIS) and early invasive adenocarcinoma, which may be very problematic. A spectrum of benign, premalignant and malignant cervical glandular lesions exhibiting gastric differentiation is emerging with lobular endocervical glandular hyperplasia (LEGH), including so-called atypical LEGH, representing a possible precursor of non HPV-related cervical adenocarcinomas exhibiting gastric differentiation; these include the cytologically bland adenoma malignum and the morphologically malignant gastric type adenocarcinoma. Stratified mucin producing intraepithelial lesion (SMILE) is a premalignant cervical lesion with morphological overlap between cervical intraepithelial neoplasia (CIN) and AIS and which is variably regarded as a form of reserve cell dysplasia or stratified AIS. It is now firmly established that there are two distinct types of vulval intraepithelial neoplasia (VIN) with a different pathogenesis, molecular events, morphological features and risk of progression to squamous carcinoma. These comprise a more common HPV-related usual type VIN (also referred to as classic, undifferentiated, basaloid, warty, Bowenoid type) and a more uncommon differentiated (simplex) type which is non-HPV related and which is sometimes associated with lichen sclerosus. The former has a relatively low risk of progression to HPV-related vulval squamous carcinoma and the latter a high risk of progression to non-HPV related vulval squamous carcinoma. Various aspects of vulval Paget's disease are also discussed.

Abstract
The International Federation of Gynecology and Obstetrics (FIGO) staging of tumours of the uterine corpus, cervix and vulva was revised in 2009. The greatest impact of the revised staging was on carcinomas of the uterine corpus. Uterine sarcomas are now staged separately. Changes to the staging system for vulvar carcinomas largely reflect the significance of lymph node status. Only minor amendments have been introduced for cervical carcinomas, which remain the only gynaecological tumours to be staged clinically. These revisions, based on recent evidence, require careful, more detailed assessment of several histological parameters at each anatomical site. The present review deals with the evidence and rationale underpinning the revisions, and includes practical guidance on tumour staging. This covers the assessment and measurement of myoinvasion and evaluation of cervical, parametrial, serosal and vaginal involvement in carcinomas of the uterine corpus; the identification and accurate measurement of stromal invasion in cervical and vulvar carcinomas; the assessment of unusual variants of carcinoma at each of these sites; and the assessment of lymph node involvement.

Abstract
McCluggage W G (2012) Histopathology New developments in endocervical glandular lesions There is evidence that the prevalence of premalignant and malignant endocervical glandular lesions is increasing in real as well as in apparent terms. In this review, new developments and selected controversial aspects of endocervical glandular lesions are covered, concentrating mainly on premalignant and malignant lesions. The terminology of premalignant endocervical glandular lesions is discussed with a comparison of the World Health Organization classification and the cervical glandular intraepithelial neoplasia (CGIN) system, which is in widespread use in the United Kingdom. Primary cervical adenocarcinomas comprise a heterogeneous group of different morphological types, and while it is known that the majority of these are associated with high-risk human papillomavirus (HPV), it has become clear in recent years that most of the more uncommon morphological types are unassociated with HPV, although they may sometimes be p16-positive. A spectrum of benign, premalignant and malignant cervical glandular lesions exhibiting gastric differentiation is now recognized; these include type A tunnel clusters, typical and atypical lobular endocervical glandular hyperplasia, adenoma malignum and gastric-type adenocarcinoma. The latter is a recently described variant of primary cervical adenocarcinoma which has a different morphological appearance to the usual endocervical type and which is probably associated with different patterns of spread and a worse prognosis. There is accumulating evidence that 'early invasive' cervical adenocarcinomas have an excellent prognosis and are suitable for conservative management. Immunohistochemical markers of value in the distinction between a primary cervical and endometrial adenocarcinoma are discussed. While it is well known that a panel of markers comprising oestrogen receptor (ER), vimentin, p16 and monoclonal carcinoembryonic antigen (CEA) is useful, several major pitfalls are pointed out and this panel of markers is predominantly of value in 'low-grade' adenocarcinomas. A related group of lesions, including cervical ectopic prostatic tissue and vaginal tubulosquamous polyp, are probably derived from para-urethral Skene's glands and may be positive with prostatic markers. Recent developments in cervical neuroendocrine neoplasms are discussed, as these are associated not uncommonly with a premalignant or malignant endocervical glandular lesion.

Abstract
This overview summarizes pathogenetic and practical aspects of (sub-)classification of cervical glandular (pre-)neoplasias and, inter alia, calls into question the usefulness of grading. In the context of the differential diagnosis of benign "imitations", the phenotypic variability of glandular precancerous lesions and carcinomas is described as well as the use of special tests to distinguish them. With regard to carcinomas, the differential diagnosis of well-differentiated neoplasias is addressed including "minimal deviation" adenocarcinoma (MDA, malignant adenoma), carcinomas with endometrioid or villoglandular morphology, and mesonephric hyper- and neoplasias. Furthermore, knowledge of HPV-negative glandular (pre-)neoplasias is covered including "gastric-type" adenocarcinomas and diagnostic algorithms for discriminating between primary and secondary cervical adenocarcinomas. Finally, comments are offered on the difficulties in recognizing early invasive adenocarcinomas, especially also the pitfalls inherent in determining the depth of invasion.

Abstract
AIMS The association between human papillomavirus (HPV) and cervical carcinoma is well known, with HPV being identifiable in almost all cervical squamous carcinomas and most adenocarcinomas. However, the prevalence of HPV in unusual morphological types of cervical adenocarcinoma has not been investigated extensively. The aim was to determine HPV status in a series of primary cervical adenocarcinomas, enriched for unusual morphological types. The relationship between HPV and p16 immunoreactivity in these neoplasms was also investigated, as it is generally assumed that in cervical neoplasms diffuse p16 expression is predictive of the presence of high-risk HPV. METHODS AND RESULTS Sixty-three cervical adenocarcinomas, comprising those of usual type (n = 43), minimal deviation type (n = 4), gastric type (n = 3), intestinal type (n = 3), mesonephric type (n = 3), clear cell type (n = 4), serous type (n = 2) and hepatoid type (n = 1) underwent linear array HPV genotyping and immunohistochemistry for p16. Overall, HPV was identified in 32 of 56 cases (57%) in which sufficient DNA was present for analysis. The most common HPV types were 16 and 18, with these being identified in 20 and 18 cases, respectively, either alone or in combination. Seventy-eight per cent of usual-type adenocarcinomas were HPV-positive, as was the single serous carcinoma in which there was sufficient DNA for analysis. In contrast, all minimal deviation adenocarcinomas and those of gastric, intestinal, mesonephric and clear cell types were HPV-negative, as was the single hepatoid carcinoma. All usual-type adenocarcinomas exhibited p16 immunoreactivity (diffuse staining in all but one case), as did 11 of 20 of those of unusual morphological type (five focal, six diffuse). CONCLUSIONS Most, but not all, cervical adenocarcinomas of usual type contain HPV, but those of unusual morphological type are almost always HPV-negative. This has implications for the efficacy of HPV vaccination in the prevention of cervical adenocarcinoma. A significant proportion of cervical adenocarcinomas are p16-positive in the absence of HPV, illustrating that in these neoplasms diffuse p16 immunoreactivity is not a reliable surrogate marker of the presence of high-risk HPV.

Abstract
A 33-year old woman had a cervical sample taken at colposcopy clinic. Seven years prior to this, at the age of 26, she had had a cytological diagnosis of cervical glandular neoplasia (cytology descriptor indicated cells suspicious of endocervical neoplasia) and severe dyskaryosis. Confirmation and treatment were by LLETZ and knife cone, and, in keeping with England and Wales National Health Service guidelines, this woman was under follow-up by the colposcopy clinic. Intervening cytological follow-up included a number of negative cytological samples interspaced with one equivocal report. A recent repeat cytology which was rather cellular contained several hyperchromatic crowded cell groups (HCCG's). Careful examination revealed benign endometrial clusters, LUS, TEM and endocervical cells in strips showing pseudostratification and loss of polarity. Following an agar block, there was positive staining for p16 and Ki-67 in the abnormal groups whilst the benign TEM cells stained positive for bcl-2.

Abstract
Most cases of cervical adenocarcinoma in situ (AIS) and adenocarcinoma are of the usual or endocervical type. However, intestinal types of AIS and adenocarcinoma exist. With an intestinal-type adenocarcinoma in the cervix, the question may arise as to whether one is dealing with a primary cervical neoplasm or direct or secondary spread from an intestinal adenocarcinoma. In organs such as the ovary, urinary bladder, esophagus, and gallbladder, intestinal-type glandular epithelium often expresses enteric markers, but this has hardly been studied in the cervix. The purpose of this study was to investigate whether intestinal-type AIS and adenocarcinoma in the cervix express enteric markers and to ascertain whether these antibodies are of value in the distinction from a metastatic intestinal adenocarcinoma. We compared the immunophenotype of these lesions with that of usual-type AIS and adenocarcinomain the cervix. Cases included were AIS of usual type (n = 6), primary cervical adenocarcinoma of usual type (n = 6), AIS of intestinal type (n = 21), primary cervical adenocarcinoma of intestinal type (n = 3), primary cervical adenocarcinoma with signet ring cells (n = 2), and colorectal adenocarcinoma involving the cervix (n = 5). All cases were stained with cytokeratin (CK) 7, CK20, monoclonal carcinoembryonic antigen (CEA), p16, and CDX2. Staining was categorized as negative, focally positive (<50% cells), or diffusely positive (50% or more cells). Usual-type AIS was always diffusely CK7 positive, typically diffusely CEA and p16 positive, and always CK20 negative. CDX2 was positive in 1 case. All usual cervical adenocarcinomas were diffusely CK7 and p16 positive, and all were immunoreactive with CEA. Five and 2 cases were CK20 and CDX2 positive, respectively. Intestinal-type AIS was diffusely CK7 positive (all cases) and typically CK20 negative and diffusely CEA and p16 positive. All but 1 case exhibited diffuse nuclear positivity with CDX2. In addition, usual-type AIS adjacent to intestinal type was CDX2 positive in 13 of 21 cases. The 3 cases of primary cervical intestinal-type adenocarcinoma were diffusely CK7 positive, focally or diffusely positive with CK20 and CDX2, and focally positive with CEA. One case was diffusely p16 positive, 1 focal and 1 negative. The foci of signet ring cells in the 2 primary cervical adenocarcinomas were diffusely CK7 and p16 positive and negative with CK20 and CDX2. Colorectal adenocarcinomas involving the cervix were typically diffusely positive with CK20, CEA, and CDX2; negative with CK7; and negative or focally positive with p16. Intestinal types of cervical AIS and adenocarcinoma exhibit a partial enteric immunophenotype, usually with diffuse expression of CDX2 and, in some cases, staining with CK20. They maintain their CK7 immunoreactivity and are usually p16 positive. Although there is immunophenotypic overlap, focal staining with CK20 together with diffuse CK7 and sometimes p16 positivity helps to distinguish intestinal types of cervical adenocarcinoma from involvement by a colorectal adenocarcinoma; CEA and CDX2 are of no value in this regard. CDX2 positivity in usual-type AIS adjacent to intestinal type and in occasional cases of pure usual-type AIS may be a reflection of early intestinal differentiation before this is morphologically apparent. Using a set of cases of AIS diagnosed in a single institution over a 7-year period (77 usual type; 13 intestinal type), intestinal type was more likely to be associated with early invasive adenocarcinoma than usual type (31% vs 17%), suggesting that intestinal differentiation may be a risk factor for invasion in premalignant cervical glandular lesions.

Abstract
BACKGROUND Uterine or endocervical biopsies that contain endometrioid adenocarcinoma with widespread squamous metaplasia are usually of endometrial origin. The presence of squamous metaplasia is said to be helpful in distinguishing endocervical from endometrial adenocarcinomas in small biopsy samples. CASE PRESENTATION A 51-year-old woman presented with post-coital and post-menopausal bleeding. Biopsy of a friable lesion in the proximal endocervical canal revealed an endocervical adenocarcinoma of endometrioid type with widespread squamous metaplasia. The latter feature initially raised the possible diagnosis of a primary endometrial adenocarcinoma. However, immunohistochemical marker studies indicated a diagnosis of primary endocervical adenocarcinoma of endometrioid type and this was confirmed at hysterectomy. CONCLUSION Squamous differentiation is not well documented in endocervical adenocarcinomas of endometrioid type and, when widespread, may represent a diagnostic pitfall for pathologists. Interpretation of small biopsies from the endocervical canal on the basis of morphology alone may lead to misdiagnosis and inappropriate surgical management.

Abstract
AIMS Gastric mucin expression has been demonstrated in a group of endocervical glandular lesions. The aim of this study was to gain further insight into endocervical lesions with a gastric phenotype. METHODS AND RESULTS Various types of tunnel clusters (TC) were examined for gastric mucin by alcian blue/periodic acid-Schiff staining and immunohistochemistry for HIK1083. Five of 34 cases of TC expressed gastric mucin defined by PAS dominant neutral mucin and immunopositivity for pyloric gland mucin. Histologically, TC expressing gastric mucin showed lobular arrangements of small to medium-sized glands composed of mucin-rich columnar cells and were classified as Flumann's type A TC. Neither type B TC nor normal endocervical glands expressed PAS dominant neutral mucin and none of them was immunopositive for pyloric gland mucin. Five patients with type A TC of gastric phenotype ranged in age from 33 to 79 years (mean 58 years) and were multiparous. Type A TC of gastric phenotype, ranging from 2 to 4 mm in maximum diameter, were incidental findings in hysterectomy specimens. CONCLUSION Type A TC of gastric phenotype could be related to lobular endocervical glandular hyperplasia of gastric phenotype. The pathogenesis of gastric metaplasia in TC remains unclear.

Abstract
PTEN, a tumor suppressor gene, appears to negatively control the phosphoinositide 3-kinase signaling pathway for regulation of cell proliferation and cell survival. Somatic PTEN mutations are involved in a variety of tumors, including endometrial carcinomas, where PTEN expression is diminished. We examined expression of PTEN in a series of cervical adenocarcinomas and precursors, using tissue microarray (TMA) technology. TMA blocks were constructed using paraffin-embedded, formalin-fixed tissues from 273 samples derived from 16 normal cervical biopsies, 119 cases of invasive adenocarcinoma, and 20 high-grade cervical glandular intraepithelial neoplasia (CGIN). Fresh 3-mum sections were cut and immunostained with PTEN, and expression was correlated with clinicopathologic variables, including histologic subtypes of adenocarcinoma. In 137 patients, PTEN expression was positive in 121 (88%). The intensity and distribution of PTEN staining in the tumor tissue were more heterogeneous than those observed in the normal tissues. There were no significant differences in distribution or intensity of PTEN expression between adenocarcinoma in situ and subtypes of invasive adenocarcinoma. Our findings show that unlike the case in most endometrial carcinomas, PTEN expression is retained during the process of carcinogenesis in the glandular cervix. There is, however, evidence of altered distribution and intensity of PTEN expression in cervical adenocarcinoma cells.

Abstract
As with biopsies from other sites in the female genital tract, immunohistochemistry is now being increasingly used in cervical pathology as an aid to diagnosis. In this review, I discuss applications of immunohistochemistry in diagnostic cervical pathology with a particular focus on recent developments. It is emphasised that immunohistochemistry is to be used as an adjunct to routine morphological examination and that no marker is totally specific or sensitive for a given lesion. Although much of this review focuses on glandular lesions, the value of markers, such as MIB1 and p16, in the assessment of pre-invasive cervical squamous lesions is discussed. In the broad field of cervical glandular lesions, topics covered include: the value of markers such as MIB1, p16 and bcl-2 in distinguishing adenocarcinoma in situ and glandular dysplasia from benign mimics; markers of mesonephric lesions, including CD10; markers of value in the diagnosis of minimal deviation adenocarcinoma, such as HIK1083; markers of value in distinguishing metastatic cervical adenocarcinoma in the ovary from primary ovarian endometrioid or mucinous adenocarcinoma. Rarely ectopic prostatic tissue occurs in the cervix, which can be confirmed by positive staining with prostatic markers. A panel of markers, comprising oestrogen receptor, vimentin, monoclonal carcinoembryonic antigen and p16, is of value in distinguishing between a cervical adenocarcinoma and an endometrial adenocarcinoma of endometrioid type. Markers of use in the diagnosis of cervical neuroendocrine neoplasms, including small cell and large cell neuroendocrine carcinoma, are discussed. It is stressed that small cell neuroendocrine carcinomas may be negative with most of the commonly used neuroendocrine markers and this does not preclude the diagnosis. p63, a useful marker of squamous neoplasms within the cervix, is of value in distinguishing small cell neuroendocrine carcinoma (p63 negative) from small cell squamous carcinoma (p63 positive) and in confirming that a poorly differentiated carcinoma is squamous in type.

Abstract
Prostatic tissue has rarely been described in the lower female genital tract. We describe 6 cases of ectopic prostatic tissue: 5 involving the cervix and 1 the vagina. The latter is the first reported example of benign prostatic tissue in the vagina. The age of the patients ranged from 21 to 65 years; and in all cases, the prostatic tissue was located within the cervical or vaginal stroma without involvement of the surface. In all cases, there were both glandular and squamous elements, which varied in prominence. In some cases, the squamous elements predominated to such an extent that the underlying glandular component was easily overlooked. In the glandular areas, a double cell layer of luminal and basal cells was focally apparent. There was little cytologic atypia or mitotic activity. Immunohistochemically, 3 of 6 cases were positive with prostate specific antigen (PSA) and all 6 cases marked with prostatic acid phosphatase (PSAP). In some of the positive cases, staining was focal. Positive staining with prostatic markers was confined to the glandular elements with no staining of the squamous areas. Immunohistochemical staining with the high molecular weight cytokeratin 34betaE12 highlighted the basal cell layer, which often extended into the center of the cellular islands, reminiscent of basal cell hyperplasia involving the prostate gland. All cases tested were CD10 positive (largely restricted to the basal cell layer), alpha-methylacyl-CoA racemase positive, and p16 negative. Estrogen receptor (ER) and progesterone receptor (PR) were negative in the glandular areas, but ER was positive in the squamous elements in all cases and PR was positive in 1 case. All cases tested were androgen receptor positive and exhibited a low MIB-1 proliferation index with only scattered positive nuclei. The presence of ectopic prostatic tissue in the lower female genital tract may be more common than is appreciated. Once the possibility is considered, the diagnosis is easily confirmed using immunohistochemistry, although staining with prostatic markers may be focal and PSA may be negative. Ectopic prostatic tissue in the lower female genital tract is almost certainly a benign condition, based on the morphology, including the presence of a double cell layer, although follow-up of larger numbers of cases is required. Possible theories of histogenesis include a developmental anomaly, metaplasia of preexisting endocervical glands, and derivation from mesonephric remnants.

Abstract
BACKGROUND Hyperplastic mesonephric remnants are an incidental finding in occasional uterine or cervical surgical specimens. We describe three cases in which such remnants were postulated to be the source of abnormal glandular cells in cervical smears. CASES In all three cases abnormal glandular cells were seen in cervical smears. Subsequent histology showed the presence of hyperplastic mesonephric remnants that communicated with the endocervical canal and were likely to be the source of the abnormal glandular cells. We believe that the key features of these cells, which may aid their distinction from other causes of glandular abnormalities, are their loose clustering, lack of significant anisocytosis and cuboidal outlines. CONCLUSION We aim to document mesonephric hyperplasia as a possible source for abnormal glandular cells in cervical smears.

Abstract
A wide array of immunohistochemical markers have been evaluated with respect to their specificity in staining dysplastic cervical cells in cervical biopsies and cervical cytological smears. However, there is still a significant demand for better biomarkers to identify neoplastic cervical glandular and squamous epithelial cells precisely. The CDKN2A gene, located on chromosome 9p21, encodes the tumour suppressor protein, p16INK4A, which decelerates the cell cycle by inactivating CDK4 and CDK6. The aim of this study was to compare and contrast the expression pattern of p16INK4A in benign and neoplastic glandular lesions and tubo-endometrioid metaplasia. All cases in each category displayed some p16INK4A expression. Adenocarcinoma and in situ cases showed a combination of intense nuclear and cytoplasmic staining. It was observed that all cases of tubo-endometrioid metaplasia showed occasional nuclear positivity and definite cytoplasmic staining. These findings may have important implications for the potential utility of p16INK4A as a biomarker for glandular dysplastic lesions. While p16INK4A has been demonstrated to be an excellent marker of cervical dysplasia in squamous neoplastic lesions of the cervix, it has potential pitfalls in cervical glandular lesions that may limit the utility of this biomarker in resolving the nature of suspicious glandular lesions, particularly in cytopathology.

Abstract
For the cytologist and clinician alike, glandular lesions pose possibly the greatest challenge in cervical screening. Worldwide, with increasing confidence in cytological prediction, terminology is evolving. In the UK, with the adoption of liquid based methods, the technical aspects of cervical cytology are being addressed, it is now time to standardise our terminology in glandular reporting. Consideration of the cytological complexity, clinical needs and international protocols is essential in this endeavour.

Abstract
OBJECTIVE Cervical adenocarcinomas are increasing in incidence each year. The aim of this study was to identify a molecular biomarker to improve early detection. STUDY DESIGN Fifty-five in situ and invasive cervical adenocarcinomas were compared with 5 normal endocervical controls by immunohistochemical analysis of p16, p21, p27, cyclin D1, cyclin E, p53, and Ki-67. Expression was scored from 0 to 8 by using an automated imaging system. Western blotting and polymerase chain reaction-based human papillomavirus (HPV) testing were performed on 16 of the invasive cases having fresh-frozen tissue. RESULTS P16 exhibited a higher mean expression score for in situ (7.4; P<.0001) and invasive cervical adenocarcinoma (6.6; P<.0001) versus controls (2.0). A cutoff p16 expression score of 5 had a sensitivity of 94.5% and a specificity of 100%. Western blotting confirmed p16 protein expression. Fourteen (88%) of 16 invasive cervical adenocarcinomas were HPV-positive. CONCLUSION P16 is a putative molecular biomarker of cervical adenocarcinoma. Overexpression appears to primarily reflect HPV-induced cell cycle dysregulation.
