Review
The human papillomavirus (HPV) belongs to the Papillomaviridae family of viruses which includes small, double-stranded DNA viral agents. Approximately 90% of HPV infections occur asymptomatically and resolve spontaneously. However, infection with high-risk viral strains can lead to the development of preneoplastic lesions, with an increased propensity to become cancerous. The location of these malignancies includes the oral cavity, cervix, vagina, anus, and vulva, among others. The role of HPV in carcinogenesis has already been demonstrated for the aforementioned neoplasia. However, regarding skin malignancies, the mechanisms that pinpoint the role played by HPV in their initiation and progression still elude our sight. Until now, the only fully understood mechanism of viral cutaneous oncogenesis is that of human herpes virus 8 infection in Kaposi sarcoma. In the case of HPV infection, however, most data focus on the role that beta strains exhibit in the oncogenesis of cutaneous squamous cell carcinoma (cSCC), along with ultraviolet radiation (UVR) and other environmental or genetic factors. However, recent epidemiological investigations have highlighted that HPV could also trigger the onset of other non-melanocytic, for example, basal cell carcinoma (BCC), and/or melanocytic skin cancers, for example, melanoma. Herein, we provide an overview of the role played by HPV in benign and malignant skin lesions with a particular focus on the main epidemiological, pathophysiological, and molecular aspects delineating the involvement of HPV in skin cancers.

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.

INTRODUCTION
Vaginal metastasis from colorectal cancer is a rare occurrence, typically associated with other metastatic lesions. Isolated metastasis is exceedingly uncommon, with only a few cases documented in the literature. Vaginal involvement in colorectal cancer primarily results from direct contiguous spread from the primary tumor.
CASE PRESENTATION
We present the case of a 70-year-old African woman diagnosed with adenocarcinoma of the middle rectum. She underwent chemotherapy, radiotherapy, and subsequent anterior resection. After 2 months, an isolated metastasis of rectal cancer was identified in the lower third of the left vaginal wall, confirmed by biopsy. Colonoscopy ruled out colorectal recurrence. Thoraco-abdominal computed tomography scan showed no distant metastases. The patient underwent abdominoperineal resection, removing the lateral and posterior vaginal wall with free macroscopic margins and a definitive colostomy. The final histopathological analysis confirmed the diagnosis of moderately differentiated adenocarcinoma of the vagina, measuring 5 × 4.5 cm. The rectal wall was extrinsically invaded by the tumor down to the muscularis propria while respecting the rectal mucosa. Resection margins were negative. The patient was discharged 1 week postoperation with no complications. Adjuvant chemotherapy was indicated, and the patient is currently tolerating the treatment well.
CONCLUSION
Vaginal metastases from colorectal cancer are extremely rare. A vigilant gynecological examination is recommended during the follow-up of colorectal cancer patients. Diagnosis can be challenging, especially if the metastatic lesion is small and asymptomatic, even after standard radiological examination. Surgical resection followed by chemotherapy is a valid option for patients with early isolated metastases.

: Neoplasms of the vagina are rare and account for 1-2% of all tumors of the female reproductive system. Primary neoplasms of the vagina are most often carcinomas originating from squamous or glandular epithelium. Of the primary glandular tumors, clear cell, endometrioid, and serous adenocarcinomas are the most common types, while mucinous and mesonephric types are very rare. Mucinous adenocarcinoma is histologically subclassified into endocervical and intestinal types. We add to the existing literature another case of an extremely rare gynecological neoplasm-primary vaginal mucinous adenocarcinoma (PVMAC) intestinal type associated with vaginal villous adenoma with high-grade dysplasia. We discuss the clinical, radiological and morphological features of this rare entity. : We report a case of a 59-year-old woman with PVMAC intestinal type associated with vaginal villous adenoma with high-grade dysplasia. The patient was evaluated with a gynecological exam, and biopsy, curettage and tumor excision were performed. The positron emission tomography-computed tomography (PET/CT) scan, at the level of the pelvis, supported the primary location of the disease. Histological and immunohistochemical methods were applied. : The gynecological examination of the vagina revealed an exophytic polypoid mass with a diameter of 3 cm, located on the posterior wall, in the area of introitus vaginae. The PET/CT scan revealed a hypermetabolic malignant formation involving the vagina and anal canal, without evidence of pelvic and inguinal lymphadenopathy, and also, it excluded disease at sites other than the vagina. The histological and immunohistochemical investigations, as well as the clinical and radiological data, lent support to the diagnosis "primary vaginal mucinous adenocarcinoma intestinal type". : PVMAC intestinal type is a rare gynecological pathology, which presents a serious challenge for oncogynecologists, radiologists and pathologists.

PloS One 2024The cervix is the lower portion of the uterus, which connects this organ to the vagina through the endocervical canal.
BACKGROUND
The cervix is the lower portion of the uterus, which connects this organ to the vagina through the endocervical canal.
OBJECTIVE
This study aimed to determine the histopathologic patterns and factors associated with cervical lesions at Jimma Medical Center from September 12, 2017, to September 12, 2019.
METHODS
A 2-year facility-based cross-sectional study was conducted from May 1 to June 30, 2020.
RESULT
In this study, cervical cancer was the most common (71%) cause of cervical lesions. Squamous cell carcinoma was the most frequent cervical cancer diagnosed during the study, accounting for 96.4% of 331 cancerous cases, followed by adenocarcinoma (3.3%). High-grade squamous intraepithelial lesions were the most frequently diagnosed precancerous lesions, accounting for 68.4% of cases. Endocervical polyps were the most commonly diagnosed benign lesions, accounting for 59.3% of cases.
CONCLUSION
The maximum age distribution of cervical lesions was in the 41-50-year age range. Squamous cell carcinoma was the most frequent type of cervical cancer. High-grade squamous intraepithelial lesions were the most frequently diagnosed precancerous cervical lesions. The most common benign cervical lesions were endocervical polyps.
RECOMMENDATION
We recommend educating the community to improve health-seeking behavior and on possible preventive strategies for cervical cancer.

Review
Small-cell neuroendocrine carcinomas (SCNECs) of the female genital tract are rare and aggressive tumors that are characterized by a high rate of recurrence and poor prognosis. They can arise from various sites within the female genital tract, including the cervix, endometrium, ovary, fallopian tube, vagina, and vulva. They are composed of cells with neuroendocrine features, such as the ability to produce and secrete hormones and peptides, and a high mitotic rate. Immunohistochemical staining for neuroendocrine markers, such as chromogranin A, synaptophysin, and CD56, can aid in the diagnosis of these tumors. This article provides an overview of the epidemiology, etiology, and risk factors associated with these tumors, as well as their clinical presentation, cellular characteristics, diagnosis, and finally the current treatment options for SCNECs, including surgery, chemotherapy, and radiation therapy, alone or in combination.

Metastasis of renal cell carcinoma (RCC) to the vaginal wall has rarely been reported in the literature. We present a case of a 48-year-old who was found to have a solitary RCC metastasis at the vaginal wall, five years following radical nephrectomy. This case is noteworthy because this late presentation is unique, with prior reports of synchronous metastasis or metastasis within two years of nephrectomy, highlighting the need to consider metastatic RCC to the vagina a possibility even many years after treatment.

A Low-Risk HPV-Associated Well-Differentiated Squamous Cell Carcinoma of the Cervix with Low-Grade Squamous Intraepithelial Lesion Morphology: Clinical and Pathologic Diagnostic Difficulties and Review of the Literature.
Approximately 95% of cervical squamous cell carcinomas are associated with high-risk HPV, with a small number of HPV-independent tumors. However, low-risk HPV types have also been detected in rare cervical squamous cell carcinomas. Low-grade squamous intraepithelial lesion-related changes are a rare morphologic finding in cervical squamous cell carcinoma. We present the case of a 30-yr-old woman who presented with pelvic pain and foul-smelling vaginal discharge showing an exophytic lesion protruding from the cervix. Repeated superficial biopsies showed a low-grade squamous intraepithelial lesion (LSIL) characterized by binucleation and koilocytosis. Chromogenic in-situ hybridization revealed the presence of HPV6/11. The absence of high-risk HPV was confirmed by PCR. After following the patient for nine months without intervention, type III hysterectomy and bilateral pelvic paraaortic lymphadenectomy were performed. Microscopic examination showed well-differentiated squamous cell carcinoma with solid epithelial islands and extensive eosinophilic cytoplasm without pleomorphism. HPV 6 and 11 were also detected with chromogenic in-situ hybridization. Neoplasm invaded the full-thickness of the cervical wall and infiltrated the vagina, parametrium, the proximal ureter and bladder. The patient who received chemoradiotherapy is disease-free at 36 months follow-up. Low-risk HPV-related well-differentiated invasive squamous lesions exist, and such lesions could be a diagnostic pitfall for gynecologists and pathologists; in these cases, radiologic-pathologic correlation and radiologic guided biopsy are mandatory.

OBJECTIVE
To report the first described case of robotic-assisted utero-ovarian transposition followed by anatomic repositioning in the pelvis and cervicovaginal anastomosis in a woman with uterine fibroids, which was performed for fertility preservation in the context of pelvic radiation for rectal cancer.
DESIGN
Description of technique and live-action narrated surgical footage showing uterine transposition and repositioning.
SETTING
University hospital.
PATIENTS
A 36-year-old woman with a new diagnosis of cT3N2M0 rectal adenocarcinoma planned for neoadjuvant chemotherapy and pelvic radiation and desired fertility preservation permissive of future pregnancy. A transvaginal ultrasound revealed a 5-cm posterior leiomyoma and a normal endometrial cavity. The patient elected for utero-ovarian transposition before chemoradiation. The patient included in this video gave consent for publication and posting of the video online, including on social media, the journal website, scientific literature websites, and other applicable sites. Per institutional guidelines, an Institutional Review Board review was not required.
INTERVENTIONS
Robotic-assisted utero-ovarian transposition was performed in an inpatient setting 2 weeks after ovarian stimulation and oocyte retrieval. She was given a gonadotropin-releasing hormone agonist for menstrual suppression after oocyte retrieval. The uterus and adnexa were transposed en bloc to the upper abdomen, with perfusion via retroflected infundibulopelvic ligaments. Intravenous indocyanine green was administered intraoperatively to visualize uterine perfusion. Three weeks postoperatively, the patient underwent surgical management of small bowel obstruction, which was successfully managed with laparoscopic adhesiolysis. The patient subsequently completed chemoradiation and had a complete response to the rectal tumor. She therefore elected for surveillance. Seven months after transposition and 2 months after completion of treatment, the patient underwent uncomplicated robotic-assisted utero-ovarian anatomic repositioning in the pelvis with cervicovaginal anastomosis. Chromopertubation confirmed tubal patency.
MAIN OUTCOME MEASURES
Restoration of normal pelvic anatomy and resumption of reproductive physiology.
RESULTS
At her 4-month postoperative visit, the cervix and vagina were normal in appearance. The patient reported the return of spontaneous menses and sexual activity without complications.
CONCLUSION
This case is unique because of the presence of bulky intramural uterine fibroids. The described technique may be useful for selected cancer patients who desire to carry a pregnancy after pelvic radiation for cancer treatment, and demonstrates that patients considering utero-ovarian transposition need not be excluded solely on the basis of the presence of uterine fibroids.

Villoglandular papillary adenocarcinoma (VPA) or villoglandular adenocarcinoma (VGA) is a rare but well-recognized subtype of cervical carcinoma. It exhibits a favorable prognosis, particularly within the childbearing age group, and is considered a rare manifestation of mucinous adenocarcinoma typically observed in individuals of reproductive age. In comparison to other adenocarcinomas, VPA generally demonstrates a more optimistic prognosis. This report details the case of a 46-year-old perimenopausal woman who presented with complaints of irregular menses and a protruding mass from the vagina. Upon examination, an exophytic growth was identified, replacing the cervix. A biopsy confirmed the diagnosis of VPA. Subsequently, the patient underwent a radical hysterectomy, followed by post-operative radiation therapy.
