Lymphoepithelioma-like carcinoma (LELC) is an uncommon variant of squamous cell carcinoma, which is histologically identical to lymphoepithelial carcinoma of the nasopharynx. LELCs have been reported at a variety of sites, including the stomach, salivary gland, thymus, cervix, endometrium, breast, skin, bladder, and lung. We report 2 LELCs of the vagina and 1 of the anal canal, the first report of LELC at the latter site. All 3 neoplasms were diffusely positive with p16 (block-type immunoreactivity) and the anal canal lesion contained high-risk human papillomavirus type 16; the 2 vaginal neoplasms underwent human papillomavirus testing but were unsuitable for analysis. All cases were Epstein-Barr virus negative. In reporting these cases, we highlight the potential for misdiagnosis and suggest an association with human papillomavirus infection similar to LELCs in the uterine cervix.

BACKGROUND
The incidence of cervical cancer (CC) in Slovenia in 2011 was 13.2 per 100,000 women. The treatment of early stages of invasive cervical carcinoma involves several surgical techniques. In this article the authors would like to present a new combination of two methods which help to preserve fertility and to improve pregnancy outcome. The first procedure, radical vaginal trachelectomy (RVT), begins with laparoscopic pelvic lymphadenectomy. All suspicious lymph nodes are sent to frozen section. If those lymph nodes are negative, the procedure continues vaginally. Almost the entire cervix is removed with parametria and vaginal cuff. Permanent cerclage stitch is applied and covered with vagina on what is left of uterus. Second procedure, laparoscopic abdominal cerclage (LAC), begins with pneumoperitoneum. Mersilene tape is introduced in the abdominal cavity and placed through the visceral peritoneum at the isthmic part of the uterus with a Berci's needle. It is knotted and remains permanently.
MATERIALS AND METHODS
For the first procedure all the patients with confirmed cervical carcinoma (FIGO Stage IA₁, IA₂, and IB₁) and with the desire for fertility were recruited. For the second procedure, all the patients after RVT and after miscarriage after 14th week of gestation were recruited.
RESULTS
RVT was performed in 15 patients and laparoscopic abdominal cerclage in three of them (21.5%). All three patients achieved pregnancies and after 36th weeks of gestation delivered by cesarean section (100%).
CONCLUSIONS
RVT alone is an indication for LAC. Considering its success, LAC should be performed before any miscarriage.

Diagnostic and Interventional Imaging Apr 2016To assess the value of transvaginal sonographic elastography (TSE) in discriminating between endometrial hyperplasia and endometrial carcinoma.
PURPOSE
To assess the value of transvaginal sonographic elastography (TSE) in discriminating between endometrial hyperplasia and endometrial carcinoma.
MATERIALS AND METHODS
A total of 61 women with post-menopausal hemorrhage and/or normal TSE were included. There were 32 women (mean age: 53.1±14.1 years) with endometrial hyperplasia, 14 women (mean age: 60.0±14.0 years) with endometrial carcinoma and 15 women (mean age: 51.9±7.8 years) with no endometrial disease who served as a control group. The strain index (SI) values obtained during TSE in each group were compared using Mann-Whitney U test and Kruskal-Wallis analysis of variance test.
RESULTS
The mean SI values were 0.80 (range: 0.30-1.30) in the endometrial hyperplasia group, 1.80 (range: 0.80-3.20) in the endometrial carcinoma group and 1.00 (range: 0.50-4.00) in the control group. No significant differences were found between endometrial hyperplasia group and control group, but significant differences were found between endometrial carcinoma and hyperplasia groups and between endometrial carcinoma and control groups (P<0.0001). TSE had a sensitivity of 81.3%, a specificity of 100%, a positive predictive value of 100% and a negative predictive value of 70% in differentiating endometrial carcinoma from endometrial hyperplasia. The area under ROC curve (AUC) to distinguish between endometrial carcinoma and endometrial hyperplasia was 0.933 (95% CI, 0.853-1.000) using a threshold SI value of 1.05. The AUC to distinguish between endometrial carcinoma and control was 0.881 (95% CI, 0.735-1.000) using a threshold SI value of 1.15.
CONCLUSION
Our results indicate that TSE can provide important information that help discriminate between endometrial carcinoma and endometrial hyperplasia.

Comparative Study
Cervical cancer is a significant public health problem, especially in low- and middle-income countries, where women have little access to cervical cancer screening; consequently 80% of cervical cancer related mortality occurs in these regions. The development of screening methods that need less infrastructure thus represents an urgent medical need. The study aims to compare the detection rates of high-risk human papillomavirus 16 and 18 E6 oncoprotein in urine, vaginal self-collected, and cervical scrapes of women using the OncoE6™ Cervical Test and compare the HPV16 and/or HPV18 E6 detection rates with the HPV DNA testing. Paired urine, vaginal self-collected and cervical specimens were collected from 124 women who participated in cervical cancer screening or treatment in this proof-of-concept study and underwent to HPV16/18-E6 testing and high-risk HPV DNA testing prior to treatment of cervical neoplasia or cancer. Concordance between urinary, vaginal and cervical HPV16/18-E6 and HPV-DNA testing was evaluated for patients classified as negative group (
carcinoma). Overall, HPV16/18-E6 oncoprotein was detected in 30.6% of cervical samples, 20.3% of self-collected vaginal samples and 21% of urine samples. Regarding the clinical sensitivity, the HPV16/18-E6 oncoprotein was not detected in CIN2 cases, and was detected at low rates in CIN3 cases. The clinical sensitivity of the HPV16/18-E6 oncoprotein for detecting invasive cervical cancer was 70% for cervical scrapes, 55% for self-collected vaginal samples and 52% for urine samples. This study reports the urinary detection of E6 oncoprotein in vivo for the first time and our results suggest that this detection is only for invasive/microinvasive lesions. Then, further protocol development and standardization to achieve a clinical sensitivity for CIN2/3 detection close to what can be achieved for invasive lesions using the physician collected cervical is needed.

Primary small cell neuroendocrine carcinoma of the vagina is a very rare disease. We present a case study of a 52-year-old female who presented to the hospital with complaints of urinary dribbling, burning micturition, pain, and per vaginal bleeding for three to four months. A firm globular mass of approximately 5-6 cm was felt in the anterior vaginal wall per speculum examination. Diagnosis of small cell neuroendocrine carcinoma was made with tissue biopsy and immunohistochemistry. Diagnostic imaging (MRI, positron emission tomography (PET)-CT) plays a vital role in reaching the diagnosis and understanding the treatment response. The patient received six cycles of chemotherapy with cisplatin and etoposide and radiotherapy, achieving a complete response, with complete regression of the lesion. The patient had no sign of tumor recurrence and locoregional or distant metastases after six months of follow-up. Nowadays, there is no need for surgery in the treatment of vaginal small cell neuroendocrine carcinoma, rather radiotherapy and chemotherapy are the treatment of choice. We report a case of neuroendocrine cancer of the vagina treated at our institution.

Journal of Lower Genital Tract Disease Jan 2015To study the clinicopathologic features of a rare disease of pagetoid urothelial intraepithelial neoplasia (PUIN) in the vulva.
OBJECTIVE
To study the clinicopathologic features of a rare disease of pagetoid urothelial intraepithelial neoplasia (PUIN) in the vulva.
MATERIALS AND METHODS
We reviewed a case of PUIN in a Chinese woman with a long history of bladder urothelial carcinoma.
RESULTS
The patient presented with vulvar pruritus for more than 1 month. Gynecologic examination showed a red, thickened, eczematoid lesion in the bilateral labia minora and a palpable 4-cm mass between the middle part of the vagina and the urethral meatus. Microscopically, the neoplastic cells with clear or pale eosinophilic cytoplasm were distributed throughout the squamous epithelium, with a predilection for the middle and basal portion in the vulva. Acantholysis-related papillary formation and pagetoid spread pattern to the normal squamous epithelium were also present. Invasive carcinoma was found underneath the unremarkable squamous epithelium in the vaginal biopsy. Immunohistochemistry demonstrated that these cells were negative for mucin stain, carcinoembryonic antigen, and 34βE12 and were strongly positive for cytokeratins 5/6, 7, 18, 19, and 20.
CONCLUSIONS
This rare entity of PUIN was associated with metastatic urothelial carcinoma and should be discriminated from vulvar Paget disease and pagetoid squamous cell carcinoma in situ.

CONTEXT.—
In women, radical cystectomy includes removal of the bladder, uterus, fallopian tubes, ovaries, and anterior vaginal wall, yet contiguous extension of urothelial carcinoma to all pelvic organs is rare and routine removal may be unnecessary.
OBJECTIVE.—
To study pelvic organ involvement in women at radical cystectomy and investigate oncologic outcomes.
DESIGN.—
Women with bladder cancer who underwent radical cystectomy at the Mayo Clinic and University of Toronto (1980-2018) were evaluated. Cancer-specific survival (CSS) was estimated with the Kaplan-Meier method; comparisons were made with the log-rank test. Associations with CSS were evaluated with Cox proportional hazard modeling.
RESULTS.—
A total of 70 women with pT4a and 83 with pT3b cancer were studied. Organs involved were vagina (n = 41 of 70; 58.6%), uterus (n = 26 of 54; 48.1%), cervix (n = 15 of 54; 27.8%), fallopian tubes (n = 10 of 58; 17.2%), and ovaries (n = 7 of 58; 12.1%); 22 of 58 patients (37.9%) had >1 organ involved. Of 70 with pT4a cancer, 64 were available for survival analysis by 3 pelvic organ groups: vaginal only, vaginal and/or cervical/uterine, and vaginal and/or cervical/uterine and/or fallopian tubes/ovarian involvement. Three-year CSS for vaginal involvement only was 39%; it was 14% if cervical/uterine involvement, and <1% if fallopian tube/ovarian involvement was included (P = .02). Among 20 women with pT4aN0/Nx and vaginal involvement only, 3-year CSS for vaginal involvement was 50%, whereas among 48 women with pT3bN0/Nx cancer, 3-year CSS was 58%, P = .70.
CONCLUSIONS.—
Isolated vaginal involvement should be separated from uterine and/or adnexal extension of urothelial carcinoma at pathologic staging. Direct ovarian extension is rare and routine removal may be unnecessary.

INTRODUCTION AND OBJECTIVES
The aim of the study was to evaluate genital sparing radical cystectomy surgery in female patients from the point of view of both oncologic and functional outcomes (with emphasis on urinary and sexual outcomes) in a single high-volume center for the treatment of muscular invasive bladder cancer.
MATERIALS AND METHODS
Between January 2014 and January 2018, 14 female patients underwent radical cystectomy with preservation of genital organs (the entire vagina, uterus, fallopian tubes, ovaries) and orthotopic urinary neobladder (Padua neobladder). Inclusion criteria were recurrent T1G3 tumors; refractory tumors after BCG therapy without associated carcinoma in situ (CIS); T2 or T3a tumors entirely resected at endoscopic transurethral resection of the bladder and not involving urethra/bladder trigone. Exclusion criteria were: T3b or higher bladder cancer, associated CIS and involvement of urethra or bladder trigone. Oncological and histopathological outcomes (Overall Survival - OS, Recurrence Free Survival - RFS), urinary outcomes (day and night incontinence, intermittent catheterization use, Sandvik Score) and sexual outcomes (Female Sexual Function Index 19 FSFI-19) were considered. The average follow-up time was 56 months.
RESULTS
Considering oncological outcomes, histologic examination reported urothelial carcinoma in 13/14 patients; 8/13 patients (61.5%) had high grade T1 stage, 3/13 patients (23%) had high grade T2 stage and finally 2/13 patients (15.5%) had high-grade T3 stage. One patient presented with embryonal rhabdomyosarcoma completely excised after surgery (PT2aN0M0). No patient developed local or metastatic recurrence (RFS 100%); OS was 100%. Considering urinary continence outcomes, 12/14 patients retained daytime and nighttime continence (85.5%); 2/14 (14.5%) complained of low stress urinary incontinence daily and nighttime urinary leakage. The Sandvik Score showed complete continence in 7/14 patients (50%); mild degree incontinence in 6/14 patients without use of incontinence devices (43%); moderate degree of incontinence in one patient (7%). The FSFI administered at 1 year from the surgery showed sexual desire in all patients (100%); subjective arousal, achievement of orgasm and sexual satisfaction in 12/14 patients (85.5%); sufficient lubrication in 11/14 patients (78.5%). Only one patient (7%) complained about dyspareunia during sexual intercourse.
CONCLUSIONS
Our study aims to demonstrate that genital-sparing radical cystectomy is a safe surgery in terms of oncologic outcomes and, most importantly, that it is beneficial in terms of urinary and sexual function. Indeed, patients' quality of life together with their psychological and emotional health should be put on the same level as oncological safety. However, it is a treatment reserved for selected patients who are strongly motivated to preserve fertility and sexual function and thoroughly informed about the benefits and complications of such a procedure.

The epidermis, the keratinized stratified squamous epithelium surrounding the body surface, offers a valuable framework to investigate how terrestrial animals overcome environmental stresses. However, the mechanisms underlying epidermal barrier function remain nebulous. In this study, we examined genes highly expressed in the human and mouse upper epidermis, the outer frontier that induces various barrier-related genes. Transcriptome analysis revealed that the messenger RNA level of hemoglobin α (HBA), an oxygen carrier in erythroid cells, was enriched in the upper epidermis compared with that in the whole epidermis. Immunostaining analysis confirmed HBA protein expression in human and mouse keratinocytes (KCs) of the stratum spinosum and stratum granulosum. HBA was also expressed in hair follicle KCs in the isthmus region; its expression levels were more prominent than those in interfollicular KCs. HBA expression was not observed in noncutaneous keratinized stratified squamous epithelia of mice, for example, the vagina, esophagus, and forestomach. HBA expression was upregulated in human epidermal KC cultures after UV irradiation, a major cause of skin-specific oxidative stress. Furthermore, HBA knockdown increased UV-induced production of ROS in primary KCs. Our findings suggest that epidermal HBA expression is induced by oxidative stress and acts as an antioxidant, contributing to skin barrier function.

Nearly three hundred thousand female patients are diagnosed with ovarian cancer in the world annually, and this number shows an increasing trend. However, characteristic symptoms caused by ovarian cancer are so few that early diagnosis remains challenging, and an effective screening method has not yet been established. Here, we conducted a case-control study in Japan to analyze the association between cervicovaginal microbiome and ovarian cancer, using 16S rRNA amplicon sequencing. Analysis of DNA extracted from cervical smear samples revealed Lactobacillus-dominant and Lactobacillus-deficient, highly-diversified bacterial communities in premenopausal and postmenopausal healthy controls, respectively, as reported for vaginal microbiota previously. We found that cervicovaginal microbiota in ovarian cancer patients, regardless of their menopausal status, were frequently a diversified community and similar to those in healthy subjects at postmenopausal ages. The diverse microbiota was associated with the major histotypes of epithelial ovarian cancer, including serous ovarian cancer and ovarian clear cell cancer. The present study implies the potential of a cervicovaginal microbiome biomarker in screening ovarian cancer in premenopausal women.
