Abstract
Atypical lobular endocervical glandular hyperplasia (ALEGH) is considered a precancerous lesion of gastric-type adenocarcinoma (GAS)/minimal deviation adenocarcinoma (MDA) characterized by an insidious onset, atypical symptoms, and often negative human papillomavirus (HPV) screening. Early screening for this disease is challenging, leading to a high rate of missed clinical diagnoses and the development of malignant tumors at the onset. Increased vaginal discharge and the presence of imaging cystic masses at the internal cervical ostium are often observed in patients with ALEGH. Therefore, we reviewed the clinical data of two cases of ALEGH that were identified and diagnosed in the early stages at our hospital. Through a comprehensive analysis of the medical history and diagnosis plan, combined with a review of relevant literature, to improve the early recognition and diagnosis of ALEGH, as well as strengthen the management of cervical precancerous lesions.

Abstract
The Silva pattern-based classification for human papilloma virus-associated invasive adenocarcinoma has emerged as a reliable system to predict risk of lymph node metastasis and recurrences. Although not a part of any staging system yet, it has been incorporated in synoptic reports as established by the College of American Pathologists (CAP) and the International Collaboration on Cancer Reporting (ICCR). Moreover, the current National Comprehensive Cancer Network (NCCN) guidelines include this classification as an "emergent concept." In order to facilitate the understating and application of this new classification by all pathologists, the ISGyP Endocervical Adenocarcinoma Project Working Group presents herein all the current evidence on the Silva classification and aims to provide recommendations for its implementation in practice, including interpretation, reporting, and application to biopsy and resection specimens. In addition, this article addresses the distinction of human papilloma virus-associated adenocarcinoma in situ and gastric type adenocarcinoma in situ from their invasive counterparts.

Abstract
OBJECTIVE To investigate the cytological findings of lobular endocervical glandular hyperplasia (LEGH) associated with adenocarcinoma and to clarify its characteristics and the coexisting adenocarcinoma using histochemistry and immunohistochemistry. METHODS Eighteen surgical cases of LEGH of the uterine cervix were retrospectively reviewed and classified into 3 groups: pure (pure type), atypical (atypical type), and LEGH with adenocarcinoma (mixed type). The mixed type is defined as LEGH or atypical LEGH with in situ or invasive adenocarcinoma. Cytological findings of conventional endocervical smear specimens (Papanicolaou stain) were analyzed. Histochemistry (periodic acid-Schiff reaction) and immunohistochemistry (M-GGMC-1, Muc-6 glycoprotein, and Ki-67) were performed using tissue specimens. RESULTS Cytologically, the pure type (7 cases) is characterized by glandular cell clusters that tended to form monolayered sheets with uniformly small nuclei and contain golden-yellowish mucin, whereas atypical (5 cases) and mixed (6 cases) types are characterized by glandular cell clusters similar to those of the pure type, but with complex glandular structures and mucin localization on the surface of glandular cell clusters. Ki-67 labeling index was significantly higher in atypical and mixed types than that in the pure type. Gastric-type mucinous carcinoma (MC-G) was observed in 2 out of 6 cases with mixed type. CONCLUSIONS LEGH is found to be associated with adenocarcinoma types other than MC-G. Complex glandular structures or mucin localization on the surface of glandular cell clusters may be useful cytological findings to detect atypical and mixed types of LEGH.

Abstract
The emerging concept of gastric-type mucinous carcinoma (GAS) of the uterine cervix has been accepted worldwide because of its aggressive clinical behaviour and the absence of high-risk human papillomavirus (HPV). GAS is included as a variant of mucinous carcinoma in the 2014 World Health Organization classification, and its recognition has provoked a discussion on endocervical adenocarcinoma as a single entity such that endocervical adenocarcinoma is now divided into HPV-associated and HPV-independent groups. This article reviews historical and conceptual aspects of GAS and its precursors, starting with minimal deviation adenocarcinoma (MDA), through the ensuing confusion, up to the recent paradigm shift in cervical adenocarcinoma subclassification. The gastric immunophenotype of MDA was demonstrated by a Japanese group in 1998 using the HIK1083 antibody, which recognises gastric pyloric gland mucin, and this elucidated the pathogenesis of this particular tumour. However, this information resulted in overdiagnosis of lobular endocervical glandular hyperplasia (LEGH), first described in 1999 and which represents pyloric gland metaplasia (PGM), as malignant. In the early 2000s the relationship between MDA and LEGH/PGM became a matter of controversy. In 2007 HIK1083 immunohistochemistry extended the morphological spectrum of endocervical adenocarcinoma showing gastric differentiation beyond MDA, which resulted in the proposal of GAS as a distinct entity including MDA as its very well-differentiated subtype. GAS is now considered to be an aggressive and chemoresistant neoplasm that is not related to high-risk HPV. The LEGH/PGM-GAS sequence is currently regarded as an HPV-independent pathway of carcinogenesis. Understanding the underlying molecular events in this process is key to the development of biomarkers for early detection and molecular targeted therapy.

Abstract
With the recent elucidation of gastric-type lesions in the female genital tract (especially in the cervix), occasional cases of endometrial adenocarcinoma displaying gastric (gastrointestinal) differentiation have been reported, but they are currently not recognized as a distinct pathologic entity. We report 9 cases of endometrial mucinous lesions which exhibit gastric (gastrointestinal)-type features by morphology and immunohistochemistry, including 4 adenocarcinomas and 5 benign mucinous lesions, in patients aged 32 to 85. The adenocarcinomas showed gastric-type morphology in all 4 cases and goblet cells in 1, with a component of benign gastric-type mucinous glands in 1 case. Immunohistochemically, the adenocarcinomas were positive for CK7 (4/4), CEA (4/4), MUC6 (3/3), PAX8 (3/4), CK20 (2/4), CDX2 (2/4), and estrogen receptor (1/4). They were negative for Napsin A (0/3), with mutation-type p53 staining in 2/4 cases, block-type p16 positivity in 1/4, and scattered chromogranin-positive cells in 1/2. Targeted next-generation sequencing revealed nonsense mutation in RB1 gene for the case with block-positive p16. Follow-up was available in all adenocarcinoma cases and indicated aggressive behavior; 2 patients were dead of disease at follow-up of 7 months to 3 years, 1 was alive with progression at 9 months, and 1 was alive without disease at 7 months. The benign mucinous lesions (including the benign component in 1 adenocarcinoma) exhibited gastric-type morphologic features in 5/6 cases, goblet cells in 5/6, and Paneth-like neuroendocrine cells in 1/6. These benign mucinous lesions were associated with an endometrial polyp in 5/6 cases. Cytologic atypia was present in 2/6 cases and a lobular architecture resembling cervical lobular endocervical glandular hyperplasia in 4/6. Immunohistochemically, the benign mucinous lesions were positive for CK7 (5/5), CDX2 (5/6), estrogen receptor (4/5), MUC6 (4/5), CK20 (3/5), PAX8 (3/5), and CEA (2/4), with scattered chromogranin-positive cells in 4/4 cases; in all cases tested Napsin A was negative, p53 was wild-type and p16 was negative. We propose the term "endometrial gastric (gastrointestinal)-type adenocarcinoma" for this distinctive group of rare aggressive endometrial carcinomas. We believe that benign or atypical gastric (gastrointestinal)-type mucinous lesions are putative precursors for these adenocarcinomas, comparable to recognized premalignant gastric-type lesions in the cervix and the vagina. Future recognition and reporting of these gastric-type endometrial mucinous lesions will help delineate their pathogenesis and clinical significance.

Abstract
CONTEXT - Cervical adenocarcinomas span a diverse group of tumors with several distinct histologic tumor types, which include endocervical, endometrioid, intestinal, villoglandular, gastric, signet ring, serous, clear cell, and mesonephric. Diagnosis of cervical adenocarcinoma, especially early diagnosis, poses a significant challenge. OBJECTIVE - To review the pathogenesis, diagnostic criteria, immunohistochemical markers, and differential diagnosis of various subtypes of human papillomavirus (HPV)-positive and HPV-negative cervical adenocarcinomas. The paper presents a concise summary of the issues that may be particularly difficult in histopathologic diagnosis, such as differentiating neoplastic lesions from benign mimics, determining the tumor type, differentiating early invasive lesions from adenocarcinoma in situ, measuring the depth of invasion, and, finally, differentiating primary cervical adenocarcinoma from uterine endometrioid adenocarcinoma and tumors metastatic from other primary sites. DATA SOURCES - The study employed a PubMed search of recently published reports. CONCLUSIONS - Early detection of HPV-positive tumor types may be aided with the expansion of HPV testing; however, early diagnosis of HPV-negative cervical adenocarcinomas will continue to pose a challenge and may require the development of additional molecular testing techniques.

Abstract
Foamy gland (FG) change is a distinctive morphological alteration most widely recognised in adenocarcinomas of the prostate and pancreas, and characterised by cells showing prominent cytoplasmic microvacuolation often with deceptively bland nuclear appearances. To our knowledge, FG alteration has not been described in endocervical neoplasia. We report four patients with gastric-type endocervical neoplasms (3 invasive and 1 in situ) in which FG change was present in 30-80% of the tumour cells. The mean age was 56.5 years (range 45-66 years) and three patients, one of whom also had post-coital bleeding, had atypical glandular cells detected on cervical cytology. Three cases showed a pure gastric phenotype and benign gastric-type changes including pyloric metaplasia, tunnel clusters and/or lobular endocervical glandular hyperplasia were also present. These cases were MUC6 positive and p16 negative on immunohistochemistry while HPV was not detected. One adenocarcinoma showed a mixed histological pattern including usual-type endocervical carcinoma and gastric-type adenocarcinoma: only the latter component expressed MUC6 and this case was p16 and HPV18 positive. This report expands the morphological spectrum exhibited by gastric-type endocervical lesions and the range of anatomical sites in which neoplasms with FG features may be encountered.

Carbonic anhydrase type IX expression in lobular endocervical glandular hyperplasia and gastric-type adenocarcinoma of the uterine cervix. Pathol Res Pract 2013; 209:173-8.

Abstract
The significance of carbonic anhydrase (CA-IX) expression in endocervical glandular lesions was determined to assess the utility of CA-IX immunohistochemistry for the identification of gastric-type endocervical adenocarcinoma and its related lesions. In this study, lobular endocervical glandular hyperplasia (LEGH) (n=5), atypical LEGH (ALEGH) (n=6), and endocervical adenocarcinomas, including usual-type (UEA) (n=6) and gastric-type (GAS) (n=7), were examined by immunohistochemistry for CA-IX expression. The proportion of positive staining and intensity was evaluated as between 0 and 3+. All 13 UEAs and GASs were positive for CA-IX, with 9 cases showing 3+ staining, and 8 cases showing positive areas exceeding 50%. All 11 LEGHs were positive for CA-IX, with all cases showing 50% or more positive areas, although only one case was 3+ positive. Five of 6 ALEGHs were positive for CA-IX, with 4 cases showing 3+ positivity in 100% of the lesion. Non-neoplastic glands were negative for CA-IX, although reserve cell populations and tubal metaplasias were positive for CA-IX. Although CA-IX appears to be involved in tumor progression and may be diagnostically useful in cases of endocervical adenocarcinoma and its precursors, LEGH can be a pitfall, and staining results should be combined with morphology.

Abstract
We describe a case of a non-invasive precursor of minimal deviation adenocarcinoma (MDA) of the uterine cervix, associated with Peutz-Jeghers syndrome (PJS). A 27-year-old woman, who had been followed for PJS, was referred to the gynecology clinic. Colposcopic examination demonstrated a small polypoid lesion in the transformation zone. Microscopic examination of the biopsy specimen demonstrated papillary proliferation of the mucinous epithelium with bland nuclear morphology. Conization revealed lobular endocervical glandular hyperplasia (LEGH) with distinct nuclear anaplasia, as well as papillary proliferation of the mucinous epithelium with mild to moderate nuclear abnormalities. This case suggests that the incipient phase of PJS-associated MDA is related to atypical LEGH ("MDA in situ"), and indicates the importance of early screening and surveillance by gynecologists in cases of PJS to detect cervical adenocarcinomas.
