endometriosis ovary tumours

Robert J Kurman, Ie-Ming Shih
The recent 2014 World Health Organization (WHO) Classification of Tumours of the Female Reproductive Organs introduced a new category of ovarian neoplasm designated "seromucinous tumours". The recognition of this distinctive group of tumors is an important addition to the classification but the term "seromucinous" has serious flaws that obscures the nature of these neoplasms. Morphologically, seromucinous tumors in addition to serous and endocervical-type mucinous epithelium, contain endometrioid, indifferent and squamous type epithelium...

BACKGROUND: Synchronous multiple primary malignancies in the female genital tract are infrequent. From 50 to 70% of them corresponds to synchronous cancers of the endometrium and ovary. To our knowledge, this is only the third case report in the international literature of three concurrent gynaecological cancers of epithelial origin. A case is presented, as well as a literature review due to the infrequency of its diagnosis and the lack of information on the subject. CLINICAL CASE: A 49-year-old woman, with previous gynaecological history of ovarian endometriosis...

Seromucinous neoplasms are a new category of ovarian epithelial tumor in the revised World Health Organization Classification of Tumours of the Female Reproductive Organs. Borderline variants are well described, but there have been few reports of seromucinous carcinomas. We report the clinicopathologic features in 19 cases of ovarian seromucinous carcinoma in patients aged 16 to 79 years (mean 47). In 16 cases, the neoplasm was unilateral and in 3 cases bilateral. The tumors ranged in size from 1.8 to 18 cm (mean 10...

INTRODUCTION: Epithelial ovarian cancer (EOC) is a heterogeneous condition with poor survival outcomes. The genetics of hereditary and sporadic ovarian cancers will be covered and its implications to management and future research are discussed. SOURCES OF DATA: Key recent published literature. AREAS OF AGREEMENT: Both genetic and environmental factors play a role in the development of EOC. Most EOCs develop sporadically and are divided into low-grade/genetically stable type I tumours and high-grade/genetically unstable type II tumours...

UNLABELLED: : There is an increasing awareness that malignant transformation of endometriosis is an uncommon but distinct entity. We review one such case of a clear cell carcinoma arising within an endometrioma of a rectus sheath scar. These malignancies have a favourable prognosis, with extra-gonadal disease commonly associated with unopposed estrogen replacement therapy. PRESENTATION: A 56-year-old female presented to TQEH for management of post menopausal bleeding...

Clear cell carcinomas of the female genital tract are rare tumours with a fearsome reputation for having poor responses to conventional platinum-based chemotherapy and poor prognosis. However, it is now clear that early-stage ovarian clear cell carcinoma has an excellent prognosis and may not require any adjuvant therapy. In addition, radiotherapy may also have a key role to play in adjuvant management of clear cell tumours. Identification of patients who truly do not need adjuvant chemotherapy is important...

BACKGROUND: Endometriosis is a chronic, recurring condition that can develop during the reproductive years. It is characterised by the development of endometrial tissue outside the uterine cavity. It is the most common cause of pelvic pain in women. This endometrial tissue development is dependent on oestrogen produced primarily by the ovaries and, therefore, traditional management has focused on suppression of ovarian function. Mounting evidence shows that altered immune function plays a crucial role in the genesis and development of endometriosis...

A 56-year-old female, with a past history of hysterectomy 13 years previously due to uterine myomata, presented with complaints of pain around the anus of a few months duration. Three years previously she underwent a colonoscopy, which was found to be unremarkable. A high suspicion of a submucosal tumour of the rectum in endoscopic examinations was confirmed by endoscopic ultrasound. The biopsy could not specify the tumour characteristics. Based on the diagnosis of a 4 cm submucosal tumour with infiltration of bowel wall and regional lymph nodes the affected segment was resected...

Clear cell tumours of the ovary are relatively uncommon. Most of them are clear cell carcinomas. Benign and borderline clear cell tumours are extremely rare and almost always fibromatous. We report a case of a 34-year-old woman. Ultrasound and computed tomography showed a right ovarian mass 8 cm in diameter. The patient underwent right salpingo-oophorectomy. Microscopic examination revealed glands and cysts different in size and shape within an abundant stromal component without evidence of stromal invasion...

BACKGROUND: The Y-box-binding protein (YB-1) is described as a potential oncogene highly expressed in tumors and associated with increased cell survival, proliferation, migration and anti-apoptotic signaling. The aim of our study was to examine the expression and role of YB-1 in human endometriosis (Eo) and its association with cell survival, proliferation and invasion. METHODS: We analyzed the gene and protein expression levels of YB-1 by quantitative real-time RT-PCR and immunoassays, respectively, in peritoneal macrophages, ovarian endometrioma and eutopic endometrial tissues/cells derived from women with (n= 120) and without (n= 91) Eo...

PURPOSE: To evaluate the blood flow changes and their relationships to microvessel density (MVD) and thrombospondin-1 (TSP-1) by transvaginal colour Doppler sonography (TV-CDS) in the ovarian interstitium to predict ovarian interstitial microvascular injury in the pathological process of ovarian endometrial cysts (OEC). METHODS: TV-CDS was preoperatively performed to detect blood flow changes in 60 patients with 76 ovarian endometrioid cysts, and flow classification and resistance indices (RI) values were recorded for analysis...

Serous, endometrioid, clear cell and mucinous histotypes are the most common epithelial ovarian cancer. Most serous cancers appear to originate from precursor lesions at the fimbriated tubal end, whereas most endometrioid and clear cell cancers seem to derive from atypical endometriosis. Data regarding hormonal factors and associated gynaecologic conditions were critically analysed with the objective of defining a carcinogenic model for sporadic epithelial ovarian cancer complying with epidemiologic and pathologic findings...

Mutation of the ARID1A gene and loss of the corresponding protein BAF250a has recently been described as a frequent event in clear cell and endometrioid carcinomas of the ovary. To determine whether BAF250a loss is common in other malignancies, immunohistochemistry (IHC) for BAF250a was performed on tissue microarrays (TMAs) in more than 3000 cancers, including carcinomas of breast, lung, thyroid, endometrium, kidney, stomach, oral cavity, cervix, pancreas, colon and rectum, as well as endometrial stromal sarcomas, gastrointestinal stromal tumours, sex cord-stromal tumours and four major types of lymphoma (diffuse large B cell lymphoma, primary mediastinal B cell lymphoma, mantle cell lymphoma and follicular lymphoma)...

AIMS: To describe the clinicopathological features of florid peritoneal mesothelial hyperplasia associated with gynaecological disease. METHODS: Review of a series of 44 cases where there was significant peritoneal mesothelial proliferation, usually on the surface of the ovary, which resulted in diagnostic problems, often including a consideration of malignancy. RESULTS: Florid mesothelial proliferation was associated with a variety of benign and malignant lesions, most commonly endometriosis...

AIMS:   Clinicopathological aspects of the endocervical-like mucinous borderline tumour of the ovary (EMBT), including higher frequencies of bilaterality, endometriosis and hormone receptor reactivity, and often admixtures of various Müllerian-type epithelia, closely resembles endometrioid tumour more than mucinous borderline tumour of the intestinal type (IMBT). Thus, the aims of this study were to determine whether EMBT is really a subtype of mucinous borderline tumours, as shown in the current classification system, and to determine the best classification for EMBT...

This study reports on anti-Müllerian hormone (AMH) in serum and follicular fluid (FF) in relation to inflammatory parameters in women with and without endometriosis undergoing IVF. Serum and FF samples were obtained from 72 women, with (n = 34) and without (n = 38) endometriosis, undergoing IVF. The concentrations of AMH, FSH, tumour necrosis factor (TNF), granulocyte-macrophage colony-stimulating factor (GM-CSF), vascular endothelial growth factor (VEGF) and several interleukins were analysed. Women with endometriosis had significantly lower AMH in serum and FF (serum: 6...

Several studies have reported that ovarian clear-cell adenocarcinoma can be derived from endometriosis. Although the clear-cell adenofibroma (CCAF), a major form of benign and borderline ovarian clear-cell tumour, has been suggested as another precursor for clear-cell adenocarcinoma (CCA), there is no supportive genetic evidence for this presumption. To examine the genetic linkage between CCAF and CCA of the ovary, we conducted allelotype analysis for both CCAF and adjacent CCA components in 14 cases of CCA associated with benign CCAF and/or borderline CCAF...

Endometriotic foci, especially ovarian ones, with epithelial cytologic atypia may be precursors of cancer. This study presents an overview of the atypical cytological and histopathological findings associated with endometriosis. Six cases of endometriosis, with atypical histological and cytological changes, were obtained from the archives of the Department of Pathology at Cleveland Clinic Foundation between year 2000 and 2003. The size of the base from which these cases were drawn was 2000 cases of endometriosis...
