Vulval epidermal cysts are rare and infrequently described in literature. They present a difficult diagnostic dilemma and surgical challenges. They most commonly occur as a late complication of female genital mutilation (FGM) and manifest as a primary condition. We present a case of a large vulval epidermal inclusion cyst, lined by vulval squamous epithelium, in a woman with a background of FGM who was referred with suspected vulval cancer. We discuss the clinical presentation, MRI findings, surgical treatment and outcome...

Epidermal growth factor receptor (EGFR)-mediated activation of the canonical Ras/MAPK signaling cascade is responsible for cell proliferation and cell growth. This signaling pathway is frequently overactivated in epithelial cancers; therefore, studying regulation of this pathway is crucial not only for our fundamental understanding of cell biology but also for our ability to treat EGFR-related disease. Genetic model organisms such as Caenorhabditis elegans, a hermaphroditic nematode, played a vital role in identifying components of the EGFR/Ras/MAPK pathway and delineating their order of function, and continues to play a role in identifying novel regulators of the pathway...

AIMS: Mammary-like adenocarcinoma (MLA) of the vulva is thought to be derived from vulvar mammary-like glands. The aim of this study was to characterize a series of MLAs by using an immunohistochemical algorithm that identifies the major molecular subtypes of breast cancer. METHODS AND RESULTS: Seven cases of vulval MLA were stained for oestrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), Ki67, epidermal growth factor receptor (EGFR), cytokeratin (CK) 5, nestin, and inositol polyphosphate-4-phosphatase (INPP4b)...

Inguinal lymph node dissection represents the gold standard of treatment for patients with vulval carcinoma. The application of minimally invasive techniques, such as robotics, in the surgical treatment of gynecologic cancer, reduced the rate of postoperative complications, which has an important impact on the quality of patients' life. Robotic inguinal lymph node dissection is a safe and oncologically effective but expensive and time-consuming approach in patients with penile cancer or melanoma. However, it is related with less postoperative complications, especially less lymphocele or lymphedema rates, and can improve the patients' quality of life while minimizing cost for health systems...

Inguinal lymphadenectomy remains the standard of care for metastatic nodal disease in cases of penile, urethral, vulval and vaginal cancers. Outcomes, including cure rates and overall and progression-free survivals, have progressively improved in these diseases with extending criteria to offer inguinal lymph node dissection for patients 'at-risk' for metastasis or loco-regional recurrence. Hence, despite declining incidence of advanced stages of these cancers, many patients will still need to undergo lymphadenectomy for optimal oncological outcomes...

BACKGROUND: Verrucous carcinoma of the vulva is extremely rare. It is a slow growing, low malignant variant of a squamous cell carcinoma with a cauliflower appearance. Women with lichen planus have an increased risk of developing vulval cancer. CASE PRESENTATION: A 79-year-old woman consulted for vulval itching. On clinical examination, a 3-cm large verrucous clitoral cancer in an area of lichen planus was seen. Based on her last clinical examination, the growth was estimated to be 1 cm(2) per month with an invasion depth after 6 months of 5 mm...

BACKGROUND: Gynaecological cancers are diagnosed in over 1000 women in Wales every year. We estimate that this is costing the National Health Service (NHS) in excess of £1 million per annum for routine follow-up appointments alone. Follow-up care is not evidence-based, and there are no definitive guidelines from The National Institute for Health and Care Excellence (NICE) for the type of follow-up that should be delivered. Standard care is to provide a regular medical review of the patient in a hospital-based outpatient clinic for a minimum of 5 years...

Basal cell carcinoma (BCC) is the most common non-melanomatous skin cancer, typically arising in sun-exposed areas such as the head and neck. Defective signaling through the Hedgehog (HH) signaling pathway forms the molecular basis for BCC. Surgery remains the mainstay of treatment. Basal cell carcinoma of the genital tract is rare as is metastatic BCC. We report a case of metastatic BCC in a young woman with previously resected vulval BCC presenting six years later with inguinal nodal recurrence and multiple lung metastases...

BACKGROUND: A nine-valent human papilloma virus (9vHPV) vaccine has been developed to prevent infections and diseases related to HPV 6/11/16/18 (as per the licensed quadrivalent HPV (qHPV) vaccine) as well as to five additional oncogenic HPV types (HPV 31/33/45/52/58). The 9vHPV vaccine has the potential to prevent 90% of cervical cancers, HPV-related anal, vaginal and vulval cancers and anogenital warts. We compared the immunogenicity and safety of the 9vHPV vaccine versus the qHPV vaccine in 16-26-year-old men...

BACKGROUND: Vulval cancer predominantly affects postmenopausal women. A smaller proportion of vulval cancers, particularly at older ages, are now thought to be associated with human papillomavirus infection than previously reported, but other risk factors have not been well examined in prospective cohort studies. METHODS: A total of 1.3 million women aged 49-65 years were followed for incident vulval cancer (ICD-10 C51). Adjusted Cox regression models were used to examine the relationship between reproductive and lifestyle factors and risk of vulval cancer...

Elucidating the mechanisms involved in sensitizing radioresistant tumors to ionizing radiation (IR) treatments while minimizing injury to surrounding normal tissue is an important clinical goal. Due to their sequence-derived specificity and properties as gene regulators in IR-affected pathways, microRNAs (miRNAs) could serve as adjuvant therapeutic agents that alter cellular sensitivity to radiation treatment. To identify radiosensitizing miRNAs, we initially utilized the Caenorhabditis elegans vulval cell model, an in vivo system developed to study IR-dependent radiosensitivity as a measure of clonogenic cell death...

BACKGROUND: The population benefit of radiotherapy for gynaecological cancer (GC) if evidence-based guidelines were routinely followed is not known. This study's aim was to address this. METHODS: Decision trees were utilised to estimate benefit. Radiotherapy alone (RT) benefit was the absolute proportional benefit of radiotherapy over no radiotherapy for radical indications, and over surgery alone for adjuvant indications. Chemoradiotherapy (CRT) benefit was the absolute incremental benefit of concurrent chemotherapy and RT over RT alone...

Despite advances in surgical treatments and the availability of more conservative treatment options, women treated for vulval cancer still experience significant complications such as urinary incontinence, lymphoedema, pruritus, sexual and intimacy issues. These issues can profoundly impact a woman's quality of life. The subjective experience of women diagnosed and treated for vulval cancer in the literature is limited, possibly due to its comparable rarity to other gynaecological and female cancers and because it was traditionally seen mainly in the elderly female population...

Vulval cancers are rare, but after primary treatment, known to recur with a high frequency (30%). Clinico-pathological predictors of recurrence have been established to a great extent. However, there is paucity of literature on predictors of early versus late recurrence. We sought to identify such predictors through a retrospective study of vulval cancer recurrences in a single cancer centre over 11 years. Age of women, depth of invasion/site of primary tumour and presence of background VIN/lichen sclerosus do not appear to affect timing of recurrence...

Invadopodia are specialized membrane protrusions composed of F-actin, actin regulators, signaling proteins, and a dynamically trafficked invadopodial membrane that drive cell invasion through basement membrane (BM) barriers in development and cancer. Due to the challenges of studying invasion in vivo, mechanisms controlling invadopodia formation in their native environments remain poorly understood. We performed a sensitized genome-wide RNAi screen and identified 13 potential regulators of invadopodia during anchor cell (AC) invasion into the vulval epithelium in C...
