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.

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.

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.

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.

Efficacy and influencing factors of CO laser, topical photodynamic therapy versus therapy combined with CO laser pretreatment for vaginal low-grade squamous intraepithelial lesions with high-risk HPV infection.
BACKGROUND
Vaginal intraepithelial neoplasia (VaIN) is a group of diseases of squamous epithelial dysplasia and carcinoma in situ occurring in the vagina, which is associated with high-risk human papillomavirus (HR-HPV) infection.
OBJECTIVES
To evaluate the efficacy and safety of Carbon dioxide (CO) laser, 5-aminolevulinic acid photodynamic therapy (PDT) and PDT combined with CO laser pretreatment for VaIN1 with HR-HPV infection, and analyze the factors affecting the clearance of HR-HPV.
METHODS
Patients with HR-HPV infection and pathological diagnosis of VaIN1 and received laser or PDT or PDT combined with laser pretreatment were recruited. A total of 45 patients received one to three times CO laser (laser Group), 15 patients received three times PDT (PDT Group) and 15 patients received CO laser once and PDT three times (laser + PDT Group). HPV testing, cytology and colposcopy examinations at 3-6 months and 9-12 months after treatment were analyzed to assess the outcomes of the treatment.
RESULTS
There was no significant difference in regression rate of VaIN1 among the laser Group, the PDT Group and the laser + PDT Group (3-6 month follow-up: 57.78% vs 73.3% vs 80 %, 9-12 month follow-up: 68.89% vs 80% vs 86.67 %, P>0.05). HR-HPV remission rates were also similar in the three groups (3-6 month follow-up: 26.67% vs 46.67% vs 46.67 %, 9-12 month follow-up: 40 % in all groups, P>0.05). Compared to HR-HPV negative group, patients in the HR-HPV positive group were older and had more pregnancies. Menopause and multiple vaginal lesions were more common in the HR-HPV positive group. Adverse reactions were mild in the PDT Group. The laser Group and the laser + PDT Group had more adverse effects, such as increased vaginal secretion, vaginal bleeding, scarring and local pain.
CONCLUSION
For patients with VaIN1 at risk of progression, ALA-PDT presents itself as a viable choice for those who are well-informed and can consent to its costs and benefits. The addition of CO laser pretreatment may not increase the benefit of ALA-PDT treatment of VaIN1. Older age, menopause, more times of pregnancies, and multiple vaginal lesions might affect HR-HPV regression.

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.
