Mapping-by-sequencing has become a standard method to map and identify phenotype-causing mutations in model species. Here, we show that a fragmented draft assembly is sufficient to perform mapping-by-sequencing in non-model species. We generated a draft assembly and annotation of the genome of the free-living nematode Oscheius tipulae, a distant relative of the model Caenorhabditis elegans We used this draft to identify the likely causative mutations at the O. tipulae cov-3 locus, which affect vulval development...

The main aim of the study was to evaluate associations between morphological variability of Trichuris females from sheep and roe deer and their rDNA polymorphism in whipworm populations from the Czech Republic. The results introduced the use of new molecular markers based on the internal transcribed spacer (ITS)1-5.8S RNA-ITS2 region polymorphisms, as useful tools for the unambiguous differentiation of congeners Trichuris ovis and Trichuris discolor. These markers revealed both parasites in roe deer and in sheep; however, T...

To determine whether a subset of primary extramammary Paget disease (EMPD) may originate in anogenital mammary-like glands (AGMLG), the authors studied 181 specimens of EMPD, detailing alterations in AGMLG. The latter were identified in 33 specimens from 31 patients. All patients were women, ranging in age from 38 to 93 years (median, 65 y). In all cases, lesions involved the vulva and in 1 patient the perianal skin was affected. Histopathologically, AGMLG manifested changes identical to columnar cell change (CCC) (87...

Human Papillomavirus (HPV) infection has been recognized as the main etiologic factor in the development of various cancers including penile, vulva, oropharyngeal and cervical cancers. In the development of cancer, persistent HPV infections induce E6 and E7 oncoproteins, which promote cell proliferation and carcinogenesis resulting elevated levels of host antibodies (e.g., anti-HPV16 E7 antibody). Currently, these cancers are clinically diagnosed using invasive biopsy-based tests, which are performed only in centralized labs by experienced clinical staff using time-consuming and expensive tools and technologies...

This report describes a rare case of invasive extramammary Paget disease of the vulva with signet ring cell morphology in a 58-yr-old woman with a history of signet ring cell carcinoma of the stomach. This case was initially misinterpreted as a metastatic gastric carcinoma to the vulva because an initial small, superficial biopsy specimen showed infiltration of signet ring cells in the dermis without intraepidermal Paget cells. However, a surgically resected specimen showed concordant immunophenotypes in both intraepidermal Paget cells and intradermal signet ring cell components with immunoreactivity to cytokeratin (CK) 7, CEA, and gross cystic disease fluid protein-15, and immunonegativity for CK20, MUC5AC, and MUC6...

In this updated systematic review and meta-analysis, we estimate the pooled prevalence of human papillomavirus (HPV) DNA and HPV type distribution in squamous cell carcinoma of the vulva (vulvar cancer) and vulvar intraepithelial neoplasia (VIN). PubMed, Embase and Cochrane Library databases were used to identify studies published between 1990 and 2015 and using a PCR-based or hybrid capture test to evaluate the presence of HPV DNA in vulvar cancer or VIN. Pooled estimates of the HPV prevalence with corresponding 95% confidence intervals (CI) were calculated based on a random effects model...

Pressure ulcers may develop in different locations. Vulvar pressure ulcers can be easily misdiagnosed and, moreover, have been rarely reported in the literature. Surgical procedures that involve prolonged pressure on this area may trigger these lesions. CASE REPORT: The authors present a case of a vulvar pressure ulcer secondary to the use of a perineal post to provide countertraction during surgical repair of a hip fracture. Diagnosis was made after excluding other possible causes with anatomopathological and microbiological analysis...

BACKGROUND: The effects of pediatric solid organ transplantation on cancer risk may differ from those observed in adult recipients. We described cancers in pediatric recipients and compared incidence to the general population. METHODS: The US transplant registry was linked to 16 cancer registries to identify cancer diagnoses among recipients <18 years old at transplant. Standardized incidence ratios (SIRs) were estimated by dividing observed cancer counts among recipients by expected counts based on the general population rates...

Human papillomavirus (HPV) is the causative agent of 5% of human cancers. HPV infection is necessary for the development of cervical cancer and is responsible of a variable percentage of cancers of anus, vulva, vagina, penis, and oropharynx. Since 2007, 2 vaccines against HPV have been commercially available in Spain: bivalent (HPV types 16/18), and tetravalent (HPV types 6/11/16/18). In order to extend the protection afforded by HPV vaccines, a clinical program was launched in 2006 for the new nonavalent vaccine, including 9 HPV types (6/11/16/18/31/33/45/52/58)...

Idiopathic lymphoplasmacellular mucositis (ILPM) is a group of disorders histologically characterized by dense infiltrates of lymphocytes and plasma cells in submucosa. These lesions are initially observed on the glans penis and vulva, and later on buccal mucosa, lips, gingiva, tongue, epiglottis, larynx, and other mucosal surfaces have also been reported. We have reviewed the previously reported cases of ILPM with lip involvement, outlining the clinical presentation, treatment and outcome of the entity to date...

Papular acantholytic dermatosis of the vulva is a rare, chronic disorder and is an entity that remains to be fully understood. It shares clinical and histopathological overlap with Darier disease and Hailey-Hailey disease. We describe a 30-year-old woman with papular acantholytic dermatosis of the vulva. The lesions consisted of whitish papules and erosions on the labia majora. Histologically, there was hyperkeratosis and focal parakeratosis with acantholytic and dyskeratotic cells. She did not respond completely to topical steroids but clinical improvement occurred after the use of topical tacrolimus...

Purpose The aim of this study was to determine the risk of human papillomavirus (HPV)-related carcinomas and premalignancies in women diagnosed with cervical intraepithelial neoplasia grade 3 (CIN3). Knowledge of this risk is important to preventing the development and progression of other HPV-related premalignancies and carcinomas, by considering prophylactic HPV vaccination and/or by paying increased attention to other HPV-related carcinomas and premalignancies when CIN3 is identified. Methods Women diagnosed with a CIN3 between 1990 and 2010 were identified from the Dutch nationwide registry of histopathology and cytopathology (PALGA) and matched with a control group of women without CIN3...

Vulvar cancer accounts for less than 1% of malignancies in women. Verrucous carcinoma of the vulva is a rare histological variation, comprising less than 1% of vulvar cancer cases. Although it is characterized as being locally invasive, the condition is not associated with metastatic spreading. Lesions present in the form of a verrucous, ulcerated, and bleeding tumor that can reach large dimensions. This type of tumor can be mistaken for condylomata, both macroscopically and microscopically. We report the case of an 81-year-old patient with a large vulvar tumor presented for eight years, initially considered as a Buschke-Löwenstein tumor...

RATIONALE: Lipoid congenital adrenal hyperplasia (LCAH) is extremely rare, but is the most fatal form of congenital adrenal hyperplasia resulting from mutations in the steroidogenic acute regulatory protein (STAR) gene. LCAH arises from severe defects in the conversion of cholesterol to pregnenolone, the precursor of all steroids. PATIENT CONCERNS: A case was reported that an 11-month-old Chinese girl who presented with a sex development disorder and hyponatremia...

BACKGROUND: Human papillomavirus (HPV) has proven to be the cause of several severe clinical conditions on the cervix, vulva, vagina, anus, oropharynx and penis. Several studies have assessed the costs of cervical lesions, cervical cancer (CC), and genital warts. However, few have been done in Africa and none in Swaziland. Cost analysis is critical in providing useful information for economic evaluations to guide policymakers concerned with the allocation of resources in order to reduce the disease burden...

We aimed to investigate the risk factors for cervical intraepithelial neoplasia (CIN) in Jiexiu, Shanxi Province, China. Twenty thousand eligible married women (age: 18-65 years) were administered with a questionnaire on potential risk factors for CIN and underwent liquid based Pap test. All women with abnormal cytological results underwent colposcopy with biopsy. Based on the biopsy pathology results, women were then assigned to either study group (with CIN) or control group (negative for histological results and volunteered to participate in the follow up study)...

REVIEW
Elena Sophie Prigge, Magnus von Knebel Doeberitz, Miriam Reuschenbach
Human papillomaviruses (HPV) are widespread DNA viruses that can infect epithelial cells of the skin and mucosa. Most HPV infections remain clinically unapparent and clear spontaneously. In few cases, however, HPV infections persist and can cause benign and malignant neoplasms at different anatomic locations. Malignant HPV-induced neoplasms are caused by distinct types of HPV (oncogenic or high-risk (HR) HPV types) and present in the anogenital (anus, penis, uterine cervix, vagina and vulva) and head and neck (particularly oropharynx) region...
