Abstract
In the last two decades or so, a spectrum of benign, premalignant and malignant cervical glandular lesions exhibiting gastric differentiation has been described, with gastric-type adenocarcinoma representing the most common human papillomavirus (HPV)-independent cervical adenocarcinoma. More recently, limited literature has reported a variety of gastric-type glandular lesions at other sites within the female genital tract and, as in the cervix (the most common site for these lesions), a spectrum of benign, premalignant and malignant lesions has been proposed. We provide an update and review of the emerging spectrum of gastric-type glandular lesions at female genital tract sites other than the cervix. In the endometrium, putative gastric-type glandular lesions include mucinous metaplasia of gastric-type, atypical mucinous proliferation of gastric-type and gastric-type adenocarcinoma. Similarly in the vagina, gastric-type adenosis, atypical adenosis and adenocarcinoma have been described. There have also been occasional reports of gastric-type lesions involving the ovary and fallopian tube. We provide guidance on how to recognise gastric-type lesions morphologically and immunophenotypically and stress that sometimes these lesions occur at more than one site within the female genital tract (synchronous/multifocal gastric-type lesions of the female genital tract), sometimes in association with Peutz-Jeghers syndrome.

Abstract
Morphologic (ie, hematoxylin and eosin) evaluation of the Mullerian tract remains the gold standard for diagnostic evaluation; nevertheless, ancillary/biomarker studies are increasingly utilized in daily practice to assist in the subclassification of gynecologic lesions and tumors. The most frequently utilized "biomarker" technique is immunohistochemistry; however, in situ hybridization (chromogenic and fluorescence), chromosomal evaluation, and molecular analysis can also be utilized to aid in diagnosis. This review focuses on the use of immunohistochemistry in the Mullerian tract, and discusses common antibody panels, sensitivity and specificity of specific antibodies, and points out potential diagnostic pitfalls when using such antibodies.

Abstract
PURPOSE Rare minimal deviation adenocarcinoma (MDA) diagnosed postoperatively as incidental finding of a suspicious cervical lesion at laparoscopy, emphasizing it represents a diagnostic challenge mimicking both benign and malignant cervical lesions with often overlapping imaging characteristics-case report and literature review. CASE PRESENTATION 35-year-old Gravida with primary infertility presented with a suspicious cervical lesion and complained about menorrhagia, hyper-/dysmenorrhea. Clinical examination was unremarkable, transvaginal scan presented a 42 × 38 × 28 mm sized cervical lesion (i.e. fibroid) without hypervascularization. Unexpectedly, the diagnosis of minimal deviation adenocarcinoma in tissue sample taken from suspicious cervical lesion at laparoscopy was revealed in final pathological report. According to suspected early stage of MDA a radical abdominal hysterectomy (PIVER III/IV), bilateral salpingo-oophorectomy, omentectomy, pelvic and para-aortic lymphadenectomy was scheduled. Final histology report confirmed: "MDA", G2, FIGO pT1b1, pN0 (0/23 LN) L0 V0 Pn0 R0. RESULTS Ultrasonography may indicate MDA throughout the examination of vascularization/echogenicity with possibility of mimicking benign lesions with similar characteristics. Magnetic resonance imaging shows no pathognomonic signs for MDA. Subsequently, a review of literature was conducted and main factors affecting the prognosis of MDA considering diagnostic tools, clinical stage, histopathological results and surgical protocols were analyzed. CONCLUSIONS Minimal deviation adenocarcinoma represents one of rare cervical adenocarcinomas without HPV-association. While it is crucial to differentiate benign from malignant lesions in this subtype, imaging characteristics often overlap and may not provide a specific diagnosis. Therefore, it should be considered in suspicious multicystic cervical lesions and inconclusive PAP-smear. Definitive diagnosis of this subtype should be based on cervical biopsy.

Abstract
AIMS Gastric-type endocervical adenocarcinoma (EA) is characterised by aggressive behaviour and pathogenesis independent of human papillomavirus infection. Because of its morphology and frequent mutation-pattern expression of p53, gastric-type EA may be confused with several types of endometrial carcinoma, particularly in biopsy and curettage specimens. HIK1083 and MUC6 are immunohistochemical markers used to support a diagnosis of gastric-type EA; however, the rates of expression of these markers in endometrial tumours are largely unknown. We therefore aimed to assess the expression of HIK1083 and MUC6 in a cohort of different types of endometrial carcinoma. METHODS AND RESULTS Ninety-one endometrial carcinomas (56 endometrioid, 16 clear cell, and 19 serous) from 91 patients treated with hysterectomy were included. A representative tumour block from each case was used for immunohistochemical staining with HIK1083 and MUC6. The percentage of stained cells (0-100%) and average staining intensity (weak, moderate, and strong) were recorded for both markers. None of 91 cases expressed HIK1083. In contrast, 66% (60/91) of cases showed at least focal expression of MUC6; importantly, 54 of 60 (90%) positive cases showed moderate or strong staining. Five of 60 (8%) cases showed MUC6 staining in ≥50% of tumour cells. Endometrioid tumours (49/56, 88%) were more likely to express MUC6 than cases of clear cell (1/16, 6%) or serous (10/19, 53%) carcinoma. DISCUSSION Endometrial carcinoma often expresses MUC6. In contrast, HIK1083 is consistently negative, and thus, when positive, is a more reliable marker for distinguishing gastric-type EA from some of its endometrial mimics.

Abstract
Gastric-type cervical adenocarcinoma (GCA) is a human papillomavirus-unassociated, aggressive, chemorefractory tumor. Well-differentiated examples may exhibit bland morphologic appearances, which could potentially lead to misdiagnosis, particularly in limited material. We sought to characterize the morphologic features of GCA in surgical biopsy and cytology specimens. We identified patients with histologic diagnoses of GCA or minimal-deviation adenocarcinoma between 2004 and 2017. Available slides from biopsy, curettage, and cytology specimens were reviewed. Fifty-nine specimens (37 histology, 22 cytology) were reviewed from 23 patients, including histology specimens alone from 6 patients, cytology specimens alone from 4 patients, and both types of specimen from 13 patients. The median patient age was 52 yr (range, 29-83 yr). Biopsies showed well-to-moderately differentiated adenocarcinomas composed of cells with pale or foamy cytoplasm and well-defined cytoplasmic borders. Nuclei exhibited mild-to-moderate pleomorphism with small nucleoli. The diagnosis was challenging in a minority of biopsies in which neoplastic glandular epithelium was scant, fragmented, and/or well differentiated. Cytology slides showed single and crowded clusters of tumor cells with pale, foamy, and/or vacuolated cytoplasm and well-defined cytoplasmic borders. Nuclei were moderately pleomorphic, round to oval with one or more nucleoli. Of 20 submitted biopsies, GCA was suspected by the submitting pathologist in only 5 (25%) cases. Awareness of the morphologic features and use of confirmatory ancillary studies (eg, immunohistochemistry for markers of gastric differentiation and human papillomavirus testing) will allow accurate diagnosis of these aggressive tumors in biopsy and cytology specimens.

Abstract
Cancer of the uterine cervix is the fourth most common cancer in women worldwide, and the fourth leading cause of cancer death in women. Squamous cell carcinoma is the first type of cervical cancer (about 75% of cases), and adenocarcinoma the second. Adenocarcinoma of the uterine cervix were redefined in the 2014 WHO classification. Endocervical adenocarcinoma, usual type, is the mose common. Mucinous adenocarcinoma were classified by this classification into different subtypes: gatric type, intestinal type and signet-ring cell type. This literature review shows the caracteristics of these various subtypes of cervical cancer, little known. These are physiopathological, clinical, cytological histological, pronostic caracteristics, and their treatments.

Abstract
The most common hereditary gynaecological tumour syndromes are hereditary breast and ovarian cancer syndrome and Lynch syndrome. However, pathologists also may encounter gynaecological tumours in women with rare hereditary syndromes. Many of these tumours exhibit distinctive gross and microscopic features that are associated with a risk for an inherited gene mutation. The sensitivity and specificity of these tumour pathology features for predicting an inherited mutation vary depending on the syndrome. By recognising these tumour features, pathologists may potentially contribute to the diagnosis of an unsuspected syndrome by recommending referral of the patient for formal risk assessment by genetic counselling. Patients additionally benefit from diagnosis of an inherited syndrome because many also carry a lifetime risk for developing primary malignancies outside of the gynaecological tract. Early diagnosis of an inherited syndrome permits early screening, detection, and management of additional malignancies associated with the syndrome. This review highlights these rare syndromes and their tumour pathology, including Peutz-Jeghers syndrome (gastric type mucinous carcinoma of the cervix; ovarian sex cord tumour with annular tubules); hereditary leiomyoma renal cell carcinoma syndrome (uterine leiomyoma); tuberous sclerosis complex (uterine PEComa; uterine lymphangioleiomyomatosis); DICER1 syndrome (ovarian Sertoli-Leydig cell tumour; cervical embryonal rhabdomyosarcoma); rhabdoid tumour predisposition syndrome 2 (small cell carcinoma of the ovary, hypercalcaemic type); Cowden syndrome (endometrial endometrioid adenocarcinoma); naevoid basal cell carcinoma syndrome (ovarian fibroma); and Von Hippel-Lindau syndrome (clear cell papillary cystadenoma of the broad ligament).

Abstract
Most adenocarcinomas in the lower female genital tract (cervix, vagina, vulva) arise in the cervix and are associated with high-risk human papillomavirus (HPV) infection. However, there is an emerging spectrum of non-HPV-related cervical adenocarcinomas, the most common of which is so-called gastric type. In this review, the concept of gastric-type cervical adenocarcinomas and their possible precursor lesions is covered, the precursor lesions still being poorly understood. Other non-HPV-related cervical adenocarcinomas are also discussed, including new information regarding molecular events in mesonephric adenocarcinoma. A variety of primary vaginal adenocarcinomas, including clear cell, endometrioid, intestinal and gastric types are also discussed. The spectrum of benign and malignant glandular lesions involving the lower female genital tract and probably derived from misplaced Skene's (periurethral) glands is also covered.

Abstract
CONTEXT Premalignant and malignant glandular lesions of the cervix are known to often cause diagnostic problems with a variety of benign (more common) as well as other malignant mimics, the latter setting often being represented by secondary involvement by endometrioid endometrial carcinoma especially in small samplings. OBJECTIVE To highlight key histologic features and immunohistochemical markers that may be helpful in the distinction of in situ endocervical carcinoma from benign glandular proliferations, and those that separate different subtypes of invasive endocervical carcinoma, as well as invasive carcinoma from other carcinomas secondarily involving the cervix and nonneoplastic proliferations of the cervix. CONCLUSIONS Clinical and morphologic features as well as immunohistochemistry results should be used in conjunction in the differential diagnosis of glandular proliferations of the cervix, as correct interpretation has major clinical consequences for the patient in most instances (especially benign versus malignant). Immunohistochemical markers should be used as part of a panel of antibodies, as exceptions may occur to the usual pattern of staining, and if used singly, they may mislead the pathologist to establish a wrong diagnosis.

Abstract
OBJECTIVE To investigate the clinical, pathological and immunohistochemical features of minimal deviation adenocarcinoma (MDA) of the uterine cervix by conducting a retrospective study of 25 cases consecutively treated in three institutes over a 10 years period. METHODS Of 25 cases with MDA, clinical features were retrospectively reviewed, gross and micro appearances of surgical specimens of 17 operative cases were observed. Ki67, SMA, p53, PCNA, Vimentin, CEA, ER, CA125 and PR were detected on tissues from MDA and 50 cases common adenocarcinomas of the uterine cervix (AUCs) (differentiation rank: high 16, moderate 20, low 14). Their expressions were assessed in paraffin sections using the immunohistochemistry method. RESULTS MDA accounted for only 1.2% of adenocarcinomas of the uterine cervix. The main clinical manifestations were vaginal profuse, watery or mucoid discharge and irregular bleeding. Signs were cervical hypertrophy or thickening. The gross appearance showed many similarities with common AUCs. Immunohistochemical results: the positive rates for p53 and Ki67 in >50% of the cell nuclei (Ki67/50(+)) were 88% and 64% in MDA respectively, significantly higher than common AUCs (38%, 18%, P<0.01), CA 125 was 18% in MDA, clearly lower than common AUCs (58%, P<0.01). There was no difference between MDA and common AUCs for CEA, PR, Vimentin, ER, PCNA and SMA (P>0.05). No significant difference was noticed among the high, moderate and low differentiation groups in common AUCs (P>0.05). CONCLUSIONS For early stage diagnoses, MDA should be considered when cervical hypertrophy is present in patients complaining of a vaginal profuse watery or mucoid discharge and irregular bleeding. Positive immunohistochemical staining for p53, Ki67/50(+) and negative for CA125 can assist diagnosis and discrimination.

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
A subset of endocervical-type mucinous adenocarcinomas (ACs) of the uterine cervix exhibit a gastric phenotype and morphology, as reported in cases of minimal deviation AC in which the presence of human papillomavirus (HPV) has been rarely detected. To investigate the HPV-independent pathway of carcinogenesis in cases of gastric-type AC, we investigated the common high-risk HPV (hr-HPV) status in 52 nonsquamous cell carcinomas, using a PCR-based typing method and immunohistochemistry of p16INK4a (a cyclin-dependent kinase inhibitor that is overexpressed in both cancerous and precancerous cervical tissue, making it an ideal biomarker for cervical cancer cases). Using novel morphological criteria, seven of 52 (13.5%) carcinomas were designated as gastric-type ACs, all of which were negative for both hr-HPV DNA and p16INK4a. Nongastric-type ACs were frequently positive for both hr-HPV DNA (90%, 28/31) and p16INK4a (94%, 29/31) with adenosquamous and neuroendocrine carcinomas demonstrating the presence of hr-HPV DNA in 86% (6/7) and 83% (5/6) of cases, respectively. In these two types of carcinoma, 86% (6/7) and 100% (6/6) were positive for p16INK4a, respectively. Our data suggests that gastric-type AC appears to represent an oncogenic hr-HPV-independent neoplasm and therefore is a potential pitfall of HPV DNA testing and vaccination.

Abstract
BACKGROUND Precise preoperative diagnosis of minimal deviation adenocarcinoma (MDA) of the uterine cervix is often difficult because the histological features of MDA closely resemble those of normal cervical glands. OBJECTIVE To review the developments in the diagnosis and treatment of MDA over the past 35 years. SEARCH STRATEGY We performed a meta-analysis of all case reports published in the English and Chinese languages between 1975 and 2009 that included a histopathologic diagnosis of MDA. Pooled odds ratios and 95% CIs were calculated for comparisons and analyzed. RESULTS The histopathologic diagnosis of MDA remains difficult and is currently based on antigen detection by immunohistochemistry. Cytologic assessment and routine biopsy have low detection rates for MDA. Cross-sectional imaging techniques are helpful but a deep cervical biopsy or cervical conization is necessary for a definitive diagnosis. The mean survival is about 5 years for patients with stage I, 38.1 months for patients with stage II, 22.8 months for patients with stage III, and 5.4 months for patients with stage IV MDA. CONCLUSION Early diagnosis and treatment are key to improving prognosis and survival in patients with MDA.

Abstract
CONTEXT A large variety of tumors and lesions arise in the female genital tract. Although the majority of these can be correctly recognized on routine hematoxylin-eosin-stained slides, occasional cases present a diagnostic challenge. Immunohistochemical stains are extremely useful in resolving many of these problematic cases. As the knowledge in this area is constantly expanding, it is useful to have this updated information in a review form for easy access. OBJECTIVE To present our current knowledge of immunohistochemistry of the lesions of the female genital tract in a readily accessible form. DATA SOURCES The review is based on previously published articles on this topic. CONCLUSIONS Immunohistochemical stains help in reaching a conclusive diagnosis in a variety of problematic lesions seen in gynecologic pathology. As in any other system, immunohistochemical findings need to be interpreted in light of the clinical history and morphologic findings.

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
The incidence of malignant and premalignant endocervical glandular lesions is increasing. This review covers controversial and difficult aspects regarding the categorisation and diagnosis of these lesions. The terminology of premalignant endocervical glandular lesions is discussed because of the differences between the UK terminology and the widely used World Health Organisation classification. The morphology and histological subtypes of premalignant endocervical glandular lesions are described. Early invasive adenocarcinoma and difficulties in the diagnosis and recognition of this entity are covered, as is the measurement of early invasion within cervical adenocarcinoma. Several benign endocervical glandular lesions can mimic malignant and premalignant endocervical glandular lesions, and the distinction of these benign mimics from premalignant and malignant lesions using ancillary immunohistochemical studies is also covered. Antibodies used to distinguish between endometrial and endocervical adenocarcinoma, in the diagnosis of cervical minimal deviation adenocarcinoma of mucinous type (adenoma malignum), and in the diagnosis of cervical mesonephric lesions are also reviewed.

Abstract
This report provides a comprehensive review of several special types of adenocarcinoma of the uterine cervix. The clinicopathologic features of three tumors that may cause difficulties in diagnosis are detailed: adenoid basal carcinoma (epithelioma), adenoma malignum (minimal deviation adenocarcinoma), and mesonephric adenocarcinoma. Updated information on classification and clinical behavior are presented, as is data on their histochemical, immunohistochemical, and molecular profiles.

Abstract
Recent years have witnessed significant developments in the use of immunohistochemistry in diagnostic gynaecological pathology. This review details the most significant of these. In ovarian pathology, differential cytokeratin staining (CK7 and 20) assists in distinguishing between a primary ovarian adenocarcinoma and a metastatic adenocarcinoma, especially of colorectal origin. The development of markers characteristic of ovarian sex cord-stromal tumours (especially alpha-inhibin) facilitates diagnosis of these neoplasms which is often difficult by morphology alone due to the wide differential diagnosis. In the uterus, the distinction between a primary endometrial and endocervical adenocarcinoma may be facilitated by use of a small panel of antibodies, including CEA, ER and vimentin. Newly developed antibodies such as CD10 and h-caldesmon may be of use in the diagnosis of uterine mesenchymal lesions, especially in the distinction between endometrial stromal and smooth muscle lesions. Proliferation markers, such as MIB1, are of value in the cervix in the diagnosis of preinvasive squamous and glandular lesions. Recent studies have shown that cervical adenoma malignum exhibits a gastric phenotype. Advances have also been made in trophoblastic disease with the development of antibodies reactive against trophoblast such as alpha-inhibin, mel-Cam and p57. A newly developed monoclonal antibody HMGIC which is expressed in vulvovaginal aggressive angiomyxoma may prove to be of value in the often difficult distinction of this lesion from its histological mimics.
