Vulvar intraepithelial neoplasia, also known as VIN, is a non-invasive squamous lesion and precursor of squamous cell carcinoma (SCC) of the vulva. There is no screening test for vulvar intraepithelial neoplasia. Diagnosis of VIN is made clinically and confirmed with a biopsy. We describe a 66-year-old woman with a condyloma-like tumour located in the skin on the vestibule of the vagina. A biopsy sample was taken from the nodule. The definitive diagnosis is supported by the histological examination (VIN III) and immunohistochemical examination of p16(+), p53(+), and a few cell nuclei. The case provides information on the importance of multidisciplinary cooperation. Lifelong surveillance is essential since the resection of individual lesions does not guarantee the prevention of invasive cancer.

Bowen's disease (BD) is an intraepithelial squamous cell carcinoma (SCC) that commonly affects older individuals, with the vulva being a prevalent site in women. Lesions within the vagina pose a particular challenge for surgical treatment, often compromising both functional integrity and cosmesis. Photodynamic therapy (PDT) is an emerging, safe, and non-invasive technique utilizing a photosensitizer and a specific light source, widely applied in the treatment of malignancies and skin diseases.

Human papillomavirus (HPV)-related multiphenotypic sinonasal carcinoma (HMSC) is a biphasic epithelial tumor associated with HPV infection. This rare tumor primarily affects the nasal cavity and paranasal sinuses, with only two cases reported outside these locations to date-one in the breast and one in the vulva. This report presents a case of a tumor resembling an HMSC arising in the cervix.

Survivin belongs to the inhibitor of apoptosis protein (IAP) family and is encoded by the baculoviral inhibitor of apoptosis repeat-containing, or BIRC5, gene. It is preferentially expressed in cancers with functional complexity in cell signaling cascades such as extracellular signal-regulated kinases (ERK), mitogen-activated protein kinases (MAPK), heat shock protein-90 (HSP90), epidermal growth factor receptor (EGFR), phosphoinositide 3-kinase (PI3K), signal transducer and activator of transcription (STAT), hypoxia-inducible factor-1 alpha (HIF-1α), vascular endothelial growth factor (VEGF), and others. Survivin plays a role in cell division and cell death, properties that have attracted a large body of research to decipher its therapeutic and prognostic significance in cancer.

Background: Recently, the immunohistochemical markers cytokeratin 17 (CK17) and SRY-box2 (SOX2) have been evaluated as adjuncts for the diagnosis of high-grade vulvar intraepithelial neoplasia (VIN). In the present study, the aim was to assess CK17 and SOX2 expression in VIN by studying 150 vulvar lesions, originally reported as high-grade VIN and to assess the diagnostic accuracy.
Methods: All slides (H&E, p16, p53, Ki-67, CK17, and SOX2 stains) were independently assessed by six pathologists and the final diagnosis was reached in consensus meetings, as follows: 46 human papillomavirus (HPV)-independent VIN (including 30 p53 mutant and 16 p53 wild-type lesions), 58 high-grade squamous intraepithelial lesions (HSILs), 4 low-grade SILs (LSILs), 37 non-dysplastic lesions, and 5 lesions where the histology was inconclusive.

Objective: To systematically explore vulvar pathology diagnosed prior to vulvar squamous cell carcinoma (VSCC), as well as the association with tumor characteristics, stage and survival outcome, with the aim of improving vulvar cancer prevention strategies.
Methods: VSCC diagnosed between 2005 and 2019 were identified from a population-based cohort provided by the Dutch Nationwide Pathology Databank. Pathology reports were reviewed to identify vulvar pathology diagnosed before primary VSCC.
