High-grade vulvar intraepithelial neoplasia, a precursor lesion to vulvar squamous cell carcinoma, is subdivided into 2 types, classic or usual vulvar intraepithelial neoplasia (CVIN) and differentiated vulvar intraepithelial neoplasia (DVIN). CVIN, which is a human papilloma virus (HPV)-dependent lesion, is typically distinguished from DVIN, a p53 mutation-dependent process, by its distinct histomorphologic and immunohistochemical characteristics. However, distinguishing between the 2 entities becomes challenging in cases of CVIN with superimposed inflammatory changes, especially lichen simplex chronicus (LSC)...

Thermography-controlled, water-filtered infrared-A (wIRA) is a novel, effective and approved heating technique listed in the ESHO quality assurance guidelines for superficial hyperthermia clinical trials (2017). In order to assess the special features and the potential of wIRA-hyperthermia (wIRA-HT), detailed and updated information about its physical and photobiological background is presented. wIRA allows for (a) application of high irradiances without skin pain and acute grade 2-4 skin toxicities, (b) prolonged, therapeutically relevant exposure times using high irradiances (150-200 mW/cm2 ) and (c) faster and deeper heat extension within tissues...

PD-L1 (programmed cell death 1 ligand) is expressed on many cancer cells and prevents tumor cell death by blocking T cell activity. PD-L1 overexpression has been reported in squamous cell carcinomas of head and neck and lung cancer. To better understand the role of PD-L1 expression in vulvar cancer, we analyzed PD-L1 expression by immunohistochemistry in 55 well-characterized squamous cell carcinomas of vulva. PD-L1 was found in 72.7% of tumors. 27.3% of vulvar carcinomas showed moderate or strong PD-L1 expression...

Mammary analog secretory carcinoma is a primary salivary gland neoplasm with histologic, immunophenotypic, and molecular features identical to those of secretory carcinoma of the breast. Similar neoplasms have now been reported to occur in various nonmammary sites including the parotid gland, submandibular gland, sinuses, lip, skin, thyroid gland, and lung. We report, to our knowledge, the first example of a primary vulvar neoplasm with pathologic features identical to secretory carcinoma of the breast and an ETV6-NTRK3 fusion...

Background and purpose: Describe the survival rates and distribution of events on competing failure types in vulvar carcinoma after treatment with chemoradiation (CRT) or radiation (RT) alone. Material and methods: We included patients with vulvar carcinoma treated with CRT or RT between 2009 and 2014. Survival was estimated using the Kaplan-Meier method. We performed a competing risk analysis and included five competing events: loco-regional failure (LRF), distant metastasis, LRF plus distant metastasis, and death without evidence of disease, with the remaining patients denoted alive without evidence of disease...

BACKGROUND: Two etiologic pathways for vulvar squamous cell carcinoma (SCC) are described: in a background of lichen sclerosus and/or differentiated vulvar intraepithelial neoplasia and related to high-risk human papillomavirus (HPV) infection with high grade squamous intraepithelial lesion (HSIL) as precursor. The aim was to compare the predilection site and survival of HPV-related to non HPV-related vulvar SCCs. METHODS: Data of patients treated for primary vulvar SCC at the Radboudumc between March 1988 and January 2015 were analyzed...

We report on an endoscopic triple neurectomy in a female patient with vulvar carcinoma metastasized to the left groin with refractory neuropathic inguinodynia. Using a retroperitoneoscopic approach we resected the ilioinguinal, iliohypogastric, and genitofemoral nerves. The inguinodynia improved significantly; especially the reduced ability to walk was enhanced considerably. Endoscopic triple neurectomy could be a useful therapeutic option in refractory inguinal pain caused by local tumor manifestation.

BACKGROUND: The incidence of vulvar cancer is increasing, but surgical treatment-the current standard of care-often leads to unsatisfactory outcomes, especially in patients with node-positive disease. Preliminary results at our centre showed that locoregional spread of vulvar carcinoma occurs within tissue domains defined by stepwise embryonic and fetal development (ontogenetic cancer fields and associated lymph node regions). We propose that clinical translation of these insights into practice could improve outcomes of surgical treatment of vulvar cancer...

The incidence of vulvar squamous cell carcinoma (VSCC) has increased annually over the last decade. MicroRNAs (miRNAs/miRs) serve an important role in tumor progression and development. Our previous microarray studies have revealed that miR‑3147 was overexpressed in VSCC. However, its function and underlying mechanism in VSCC remain unknown. In the present study, it was confirmed by reverse transcription‑quantitative polymerase chain reaction that the expression of miR‑3147 was markedly upregulated in VSCC tissues...

Most human papillomavirus (HPV)-associated vulvar squamous cell carcinomas (VSCCs) originate from high-grade squamous intraepithelial lesions, also named usual type vulvar intraepithelial neoplasia. However, growing evidence suggests that morphologic studies have limitations in predicting HPV status in vulvar lesions. We aimed to evaluate adjacent intraepithelial lesions in a series of DNA HPV-positive VSCCs, focusing on unusual histologic patterns mimicking differentiated vulvar intraepithelial neoplasia (dVIN) or lichen sclerosus (LS)...

Carcinoma of the vulva is usually regarded as a disease of older women, with the typical age of 65-85 years. There are a limited number of reports of vulvar cancer cases younger than 30 years. These patients have usually risk factors such as human papillomavirus (HPV) infection and immunosuppression. Herein, we present a case of invasive squamous vulvar cancer in an 18-year-old patient without any risk factor. Vulvar radical local excision and bilateral inguinal sentinel lymph node biopsies were performed. The clitoris was preserved during the surgery...

OBJECTIVE: To demonstrate a case with a vulvar metastasis masquerading a primary vulvar malignancy. The clinical and histological features, mechanism, and impact to the prognosis are discussed. CASE REPORT: A 58-year-old woman presented to gynecologist for abnormal vaginal discharge. A vulvar nodule was noticed during physical examination. Biopsy showed adenocarcinoma (ADC) and she was referred for further survey under the impression of Bartholin duct ADC. Later she was further found to also have a colorectal tumor with liver metastasis and subsequently received surgery under the suspicion of a double primary cancer involving the colon and vulva...

AIMS: Human papilloma virus (HPV) has been identified as an aetiological agent in a subset of patients with vulvar squamous cell carcinoma (VSCC). The prognostic role of HPV status in VSCC patients treated with radiotherapy has not yet been determined. We investigated the associations between HPV, p16 and clinical outcome in these women. MATERIALS AND METHODS: Patients undergoing potentially curative radiation treatment for VSCC at a single institution from 2000 to 2009 were retrospectively identified...

Basal cell carcinoma (BCC) is the most common malignant skin cancer. Its genital localization is rare, and the diagnosis in this site could be challenging. Here, we report two patients with vulvar BCC and describe their clinical, dermoscopic and in vivo and ex vivo reflectance confocal microscopic (RCM) features. Dermoscopy and RCM can be useful tools for helping the clinical diagnosis of vulvar BCC and for identifying the correct surgical margins.

Vaginal and vulvar tumors are uncommon in dogs. Knowledge of canine primary clitoral neoplasia is restricted to a few case reports, and only carcinomas have been reported. Cytologic and histologic features reported in the literature seem to overlap with those of canine apocrine gland anal sac adenocarcinoma (AGASA). Clinical features also recall those of canine AGASA, such as locoregional metastases and hypercalcemia of malignancy (HM). In this study, 6 cases of primary canine clitoral carcinomas (CCCs), with and without HM, were investigated by means of cytology, histopathology, electron microscopy, and immunohistochemistry for neuroendocrine markers including chromogranin A (CGA), synaptophysin (SYN), neuron-specific enolase (NSE), and S-100...

The two main precursors of vulvar squamous cell carcinoma, usual and differentiated vulvar intraepithelial neoplasia (VIN), have distinctive etiology, pathogenesis, and natural history. Usual type VIN is often associated with high-risk HPV and differentiated VIN has de novo p53 genetic alterations that are unrelated to HPV infection. GATA-binding protein 3 (GATA3) is a tumor suppressor that shows increased expression in several types of human malignancies including breast and bladder carcinomas. Little is known regarding the expression of GATA3 in vulvar squamous neoplasms...

Vulvar squamous cell carcinoma (SCC) consists of two different etiologic categories: human papilloma virus (HPV)-associated (HPV (+)) and HPV-non-associated (HPV (-)). There have been no genome-wide studies on the genetic alterations of vulvar SCCs or on the differences between HPV (+) and HPV (-) vulvar SCCs. In this study, we performed whole-exome sequencing and copy number profiling of 6 HPV (+) and 9 HPV (-) vulvar SCCs and found known mutations (TP53, CDKN2A and HRAS) and copy number alterations (CNAs) (7p and 8q gains and 2q loss) in HPV (-) SCCs...
