(1) Background: Vaginal intraepithelial neoplasia (VaIN) is a rare premalignant disease caused by persistent human papillomavirus (HPV) infection. Diagnosing VaIN is challenging; abnormal cytology and positive HPV tests are usually the first signs, but published data on their accuracy for detecting it are rare and contradictory. The aim of this study is to compare the results of hrHPV and cytology co-testing with the histological findings of the vagina. (2) Methods: In the certified Dysplasia Unit at Erlangen University Hospital, cytology and HPV samples from the uterine cervix or vaginal wall after hysterectomy were obtained between 2015 and 2023 and correlated with histological findings in biopsies from the vaginal wall. Women without vaginal biopsy findings or concomitant cervical disease were excluded. (3) Results: In all, 279 colposcopies in 209 women were included. The histological results were: benign ( = 86), VaIN I/vLSIL ( = 116), VaIN II/vHSIL ( = 41), VaIN III/vHSIL ( = 33), and carcinoma ( = 3). Accuracy for detecting VaIN was higher in women with previous hysterectomies. Positive HPV testing during colposcopy increased the likelihood for VaIN II/III/vHSIL threefold. The detection rate for VaIN III/vHSIL was 50% after hysterectomy and 36.4% without hysterectomy. (4) Conclusions: Women with risk factors for VaIN, including HPV-16 infection or prior HPV-related disease, need careful work-up of the entire vaginal wall. Hysterectomy for HPV-related disease and a history of cervical intraepithelial neoplasia (CIN) also increased the risk for VaIN II/III/vHSIL.

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.

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.

BACKGROUND
In management of Carcinoma Cervix, Brachytherapy plays a crucial role. Most commonly used technique is Intracavitary Brachytherapy (ICBT). In cases where ICBT is not technically feasible or it may result in suboptimal dose distribution, Interstitial Brachytherapy (ISBT) is recommended. With this study we wanted to study the clinical outcome and dosimetric details of interstitial brachytherapy in gynecological cancers.
MATERIALS & METHODS
We analysed clinicaloutcome and dosimetric details of interstitial brachytherapy (ISBT) done for gynecological malignancies in our institute during the period 1st January 2013 to 31st December 2020.
RESULTS
Total of 42 interstitial brachytherapy (ISBT) details were analysed.37 patients had Carcinoma Cervix and 5 patients had Carcinoma Vagina. In the majority of the patients, ISBT dosage schedule was three fractions 7Gy each. D2cc to rectum, bladder, sigmoid and bowel were 4.88 Gy, 5.62 Gy, 3.57 Gy and 2.47 Gy respectively. Mean CTV volume was 129.89 cc. EQD2 dose to CTV combining EBRT and ISBT dose was 85.88 Gy. D90 and D100 to CTV from ISBT were 111.96% and 68.21 % of prescribed dose respectively. Grade III/IV toxicities were seen in 5 (12%) patients. Local control rates at 1year &2 years were 88% & 85.7% respectively. DFS at 1 year, 2 years and 3 years were 80.7%, 72.3% and 65.7% respectively. OS at 1year, 2 years, 4 years and 5 years were 92.5%, 65.5%, 59.5% and 42.3% respectively.
CONCLUSION
3D imagebased dosimetry with CT based planning using MUPIT implant is a feasible option for gynecological malignancies warranting interstitial brachytherapy. In view of good clinical outcomes in terms of toxicity profile, Local control, DFS and OS with acceptable GEC-ESTRO dosimetric data, we recommend routine use interstitial brachytherapy if facilities are available and in clinical situations were ISBT is indicated.

Review
BACKGROUND
Primary vaginal cancer is a rare condition. Some studies have revealed an increased risk of vaginal cancer among patients who have undergone hysterectomy for premalignant and malignant cervical disease. However, there is limited literature available on primary vaginal cancer following hysterectomy for benign conditions.
OBJECTIVES
This review aimed to investigate available evidence on clinical characteristics, treatments, and outcomes of primary vaginal cancer following hysterectomy for benign diseases. Additionally, we provide a case of a patient who developed primary vaginal cancer 10 years after undergoing hysterectomy for abnormal uterine bleeding.
SEARCH STRATEGY
We conducted a comprehensive literature search on PubMed, Scopus, Web of Science using a combination of title and abstract represented by "hysterectomy", and "vaginal cancer"; "vaginal neoplasm"; and "cancer of vagina". No article type restrictions were applied.
MAIN RESULTS
Eight studies with a total of 56 cases were included in this review. The main symptom observed was vaginal bleeding. Squamous cancer was found to be the most common type, followed by adenocarcinoma. The majority of vaginal cancer cases occurred approximately 10 years after undergoing hysterectomy. The most common location of the tumor was in the vaginal apex. The management approaches varied and details were available in 25 cases. Among these, 7 cases were treated with radiotherapy alone, 1 case received concurrent chemoradiation therapy, and the of rest of the cases underwent surgery as the primary treatment, with or without additional adjuvant therapy. Data of follow-up was available for 15 cases, with 2 cases resulting in death and 2 cases experiencing recurrence. The other cases were alive and well at the time of considered follow up.
CONCLUSION
Primary vaginal cancer after hysterectomy for benign conditions is an extremely rare condition. It is essential to have high-level evidence to guide the screening and treatment strategy for this rare condition. A part of women who have undergone hysterectomy for benign disorders can benefit from vaginal cytology evaluation. It is reasonable to postpone the initial screening after surgery and to extend the interval between subsequent screenings. Further retrospective case-control trials are expected to determine which specific subgroups of patients mentioned above might most potentially benefit from screening. The treatment decision for vaginal cancer after hysterectomy is more favorable to radiotherapy-based management rather than surgery. Vaginal endometrioid adenocarcinoma may arise from the malignant transformation of endometriosis. More studies are expected to investigate the correlation between these two diseases.

Review
PURPOSE
This systematic review aims to provide a data synthesis about the risk of neovaginal cancer in women with Müllerian anomalies and to investigate the association between the adopted reconstructive technique and the cancer histotype.
METHODS
PubMed, MEDLINE, Embase, Scopus, ClinicalTrials.gov and Web of Science databases were searched from inception to March 1st, 2023. Studies were included if: (1) only women affected by Müllerian malformations were included, (2) the congenital defect and the vaginoplasty technique were clearly reported, (3) the type of malignancy was specified.
RESULTS
Literature search yielded 18 cases of squamous cell carcinoma and two cases of vaginal intraepithelial neoplasia 3 (VAIN 3). Of these, 3 had been operated on according to the Wharton technique, 8 according to the McIndoe technique, 3 with a split-skin graft vaginoplasty, 2 according to the Davydov technique, 2 with a simple cleavage technique, 1 according to the Vecchietti technique and 1 with a bladder flap vaginoplasty. A total of 17 cases of adenocarcinoma and 1 case of high-grade polypoid dysplasia were also described. Of these, 15 had undergone intestinal vaginoplasty, 1 had been operated on according to the McIndoe technique and 1 had undergone non-surgical vaginoplasty. Finally, 1 case of verrucous carcinoma in a woman who had undergone a split-skin graft vaginoplasty, was reported.
CONCLUSION
Although rare, neovaginal carcinoma is a definite risk after vaginal reconstruction, regardless of the adopted technique. Gynaecologic visits including the speculum examination, the HPV DNA and/or the Pap smear tests should be scheduled on an annual basis.

Gynecologic Oncology Reports Dec 2023To perform a retrospective review of patients diagnosed with vaginal malignant neoplasms (VMN) in the Republic of Belarus.
OBJECTIVE
To perform a retrospective review of patients diagnosed with vaginal malignant neoplasms (VMN) in the Republic of Belarus.
METHODS
The Belarusian Cancer Registry was reviewed for patients diagnosed with VMN from 1990 to 2019. The data collected included age at diagnosis, demographic information, histology, stage, treatment modalities, and outcomes. Data were compared across decades (1990-1999, 2000-2009, and 2010-2019).
RESULTS
A total of 868 patients were diagnosed with VMN in Belarus between 1990 and 2019. The estimated age-standardized incidence rate of VMN per 100,000 female population increased from 0.1 in 1999 to 0.4 in 2019 ( < 0.05). The mortality rate for this period was 0.0-0.2 per 100,000 female population. Of all newly diagnosed cases of VMN, 70.9% ( = 615) lived in urban centers and 29.1% (n = 253) lived in rural areas. The most common histological type was squamous cell carcinoma, accounting for 78.4% of cases. The median age at diagnosis was 63.4 years (range, 15.0-87.0 years). When compared across the three decades, the number of stage I cases increased slightly more than twofold (from 19.1% to 38.5% for 1990-1999 to 2010-2019). Furthermore, the number of stage III cases decreased from 30.3% to 13.0% from 1990 to 1999 to 2010-2019. There were no significant changes in the number of patients diagnosed with stage II or IV disease over time. The overall 5-year survival rate for the entire group was 68.7 ± 5.1%, with no statistically significant difference between women living in urban centers vs. rural areas (67.8 ± 5.1% vs. 65.8 ± 10.4%; = 0.99). However, there was a 26.2% increase in the 5-year survival rate for the entire group over the study period. This increase was higher for women living in rural areas (+61.7%) than for those in urban centers (+51.3%); > 0.05. Furthermore, a comparison of 5-year adjusted survival rates between 2000 and 2015 showed increased survival for stages I, II, and III, with the most significant increase noted for stage III disease (2.4-fold increase).
CONCLUSIONS
This retrospective study found that the survival rates of women with VMN in Belarus have improved over the past 30 years. This is likely due to improvements in early detection as well as improved approaches to treatment, particularly for those living in rural areas. Additional study is needed to further understand and improve the outcomes of women diagnosed with VMN in Belarus.

A 74-year-old transgender female presented with urinary difficulty and a painful lesion at her neo-vagina, 47 years after undergoing gender-affirming vaginoplasty. Initial biopsy reported Low-Grade Squamous Intraepithelial Lesion (LGSIL), while MRI revealed no inguinal or pelvic lymphadenopathy. Patient underwent partial neo-vaginectomy with wide local excision and formal urethroplasty. Pathology revealed verrucous carcinoma of the neovagina, a rare neoplasm in transgender female patients. This case highlights the importance of considering squamous cell carcinoma in the differential diagnosis of patients presenting lesions at neo-vagina and the need of screening methods for early detection of such neoplasms.

Review
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.
