BACKGROUND: We describe an unusual presentation of lichen sclerosus in a postmenarchal, virginal girl. CASE: A 14 year-old girl first presented with acute urinary retention due to labial agglutination and developed bilateral tubo-ovarian abscesses in 10 days of the conservative management period. Abscesses were treated with antibiotherapy and percutaneous drainage; simple division of the labial agglutination and vulvar biopsies were performed with a preliminary diagnosis of lichen sclerosus...

The present study aimed to examine the associations between the protein and mRNA expression levels of ovarian cancer gene 1 (OVCA1), cyclin D1 and p16 and high-risk human papillomavirus (HR-HPV) infection in cervical lesions. The protein expression levels of OVCA1, cyclin D1 and p16 in 66 cases of cervical cancer, 64 cases of cervical intraepithelial neoplasia (CIN) and 34 normal cervix tissues were detected using immunohistochemistry. The mRNA expression levels of OVCA1, cyclin D1 and p16 in cervical cancer and normal cervix cells were detected using real-time polymerase chain reaction...

Ovarian torsion is a surgical emergency characterized by a partial or complete rotation of the ovarian vascular pedicle, causing obstruction to venous outflow followed by arterial inflow. Clinically, ovarian torsion frequently mimics other causes of acute pelvic pain such as appendicitis, diverticulitis, renal colic etc. Ultrasonography (US) is the first line imaging modality of choice for evaluation of ovarian torsion. MRI is useful as a problem solving tool in patients with equivocal or non diagnostic US studies...

Testicular and paratesticular cystadenomas arise from an oviduct-like structure, which, morphologically, is almost identical with the ovarian surface epithelium. These are very rare benign tumours of adults. They present as asymptomatic cystic lesions. Bilateral paratesticular cystadenomas are associated with the Von-Hippel-Lindau syndrome and may be associated with infertility. Most cystadenomas are benign, but a few cases of malignant transformation of embryonic remnants have been reported in the appendix testis, including cases of adenocarcinoma, cystadenocarcinoma, and a Müllerian-type epithelial tumour with a low malignant potential...

STUDY QUESTION: What is the relationship between endometriosis phenotypes superficial peritoneal endometriosis (SUP), ovarian endometrioma (OMA), deep infiltrating endometriosis (DIE) and the adenomyosis appearance by magnetic resonance imaging (MRI)? SUMMARY ANSWER: Focal adenomyosis located in the outer myometrium (FAOM) was observed more frequently in women with endometriosis, and was significantly associated with the DIE phenotype. WHAT IS KNOWN ALREADY: An association between endometriosis and adenomyosis has been reported previously, although data regarding the association between MRI appearance of adenomyosis and the endometriosis phenotype are currently still lacking...

Intraabdominal tumor dissemination is a major hallmark of epithelial ovarian cancer (EOC), but the underlying mechanisms have not been fully elucidated. The CXCR3 chemokine receptor supports migration of tumor cells to metastatic sites, but its role in ovarian cancer metastasis is largely unknown. Herein, we first screened two independent cohorts of high-grade serous ovarian cancers (HGSCs, discovery set n=60, validation set n=117) and 102 metastatic lesions for CXCR3 expression. In primary tumors, CXCR3 was particularly overexpressed by tumor cells at the invasive front...

Precise measurement of postvoid residual (PVR) urine volume is a key factor in assessing patients with voiding dysfunction, including those with lower urinary tract problems. The safe and noninvasive ultrasound bladder scan is the preferred mode to measure PVR volume. However, this procedure has a false-positive rate up to 9%, in the presence of ovarian cysts, renal cysts, ascites, or uterine myoma with cystic degeneration. Until now, cystic lesions are known to cause false positivity in ultrasound bladder scanner...

Colorectal cancer is a common cancer and a leading cause of cancer-related death worldwide. The liver is a dominant metastatic site for patients with colorectal cancer. Molecular mechanisms that allow colorectal cancer cells to form liver metastases are largely unknown. Activation of epithelial-mesenchymal-transition (EMT) is the key step for metastasis of cancer cells. We have recently demonstrated in breast cancer and ovarian serous adenocarcinoma that dual-specificity tyrosine-regulated kinase 2 (DYRK2) controls EMT...

Epithelial ovarian tumors are a group of morphologically and genetically heterogeneous neoplasms. Based on differences in clinical phenotype and genetic background, ovarian neoplasms are classified as low-grade and high-grade tumor. Borderline ovarian tumors represent approximately 10%-20% of all epithelial ovarian masses. Various histological subtypes of ovarian malignancies differ in terms of their risk factor profiles, precursor lesions, clinical course, patterns of spread, molecular genetics, response to conventional chemotherapy, and prognosis...

Breast metastases from extramammary cancers are rare and usually related to poor prognosis. The extramammary tumors most frequently exhibiting breast metastases are melanoma, lymphomas, ovarian cancer, lung, neuroendocrine tumors, and sarcomas. Due to the lack of reliable and specific clinical or radiological signs for the diagnosis of breast metastases, a combination of techniques is needed to differentiate these lesions from primary breast carcinoma or even benign breast lesions. Multiple imaging methods may be used to evaluate these patients, including mammography, ultrasound, magnetic resonance imaging (MRI), computed tomography (CT) and positron emission tomography (PET/CT)...

The chromatin remodeler AT-Rich Interactive Domain 1A (ARID1A) is frequently mutated in ovarian clear cell carcinoma (OCCC) and endometriosis precursor lesions. Here, we show that knocking down ARID1A in an immortalized endometriosis cell line is sufficient to induce phenotypic changes indicative of neoplastic transformation as evidenced by higher efficiency of anchorage-independent growth, increased propensity to adhere to collagen, and greater capacity to invade basement membrane extract in vitro. ARID1A knockdown is associated with expression dysregulation of 99 target genes, and many of these expression changes are also observed in primary OCCC tissues...

Transient Receptor Potential Vanilloid 1 (TRPV1) and Transient Receptor Potential Ankyrin 1 (TRPA1) expressed mainly by primary sensory neurons function as major nociceptive integrators. They are also present on the rat endometrium in an oestrogen-regulated manner. TRPV1 is upregulated in peritoneal and ovarian endometriosis patients, but there is no information about TRPA1 and their pathophysiological significances. In this study, patients undergoing laparoscopic surgery were investigated: severe dysmenorrhoea due to rectosigmoid deep infiltrating endometriosis ( n = 15), uterine fibroid-induced moderate dysmenorrhoea ( n = 7) and tubal infertility with no pain ( n = 6)...

REVIEW
Naveena Singh, W Glenn McCluggage, C Blake Gilks
Extra-uterine high-grade serous carcinoma (HGSC) accounts for most of the morbidity and mortality associated with ovarian carcinoma, and is one of the leading causes of cancer death in women. Until recently our understanding of HGSC was very limited, compared to other common cancers, and it has only been in the last 15 years that we have learned how to accurately diagnose this ovarian carcinoma histotype. Since then, however, there has been rapid progress, with identification of a precursor lesion in the fallopian tube, development of prevention strategies for both those with inherited susceptibility (Hereditary Breast and Ovarian Cancer Syndrome) and without the syndrome, and elucidation of the molecular events important in oncogenesis...

OBJECTIVES: Primary ovarian fibrosarcomas are extremely rare neoplasms, and only 50 cases have been reported in the English literature. Diagnosis can be difficult because of this condition's rarity, and other similar appearing mesenchymal lesions should be ruled out. METHODS: A 50-year-old postmenopausal woman came to our hospital because of abdominopelvic pain. Ultrasonography revealed a 41x33 mm heterogeneous solid mass in the right ovary. Total blood counts, biochemical parameters, and tumor markers were within normal ranges...

SPiDER-βGal is a newly-developed probe that is activated by β-galactosidase and is then retained within cells by anchoring to intracellular proteins. Previous work has focused on gGlu-HMRG, a probe activated by γ-glutamyltranspeptidase, which demonstrated high sensitivity for the detection of peritoneal ovarian cancer metastases in an animal model. However, its fluorescence, after activation by γ-glutamyltranspeptidase, rapidly declines over time, limiting the actual imaging window and the ability to define the border of lesions...
