The aim of the present review was to illustrate how dysregulation of hormonal signaling regulates expressional changes of spatially associated genes in endometriosis. From a multi‑platform endometriosis dataset, an integrated analysis was p…

Ovarian clear cell carcinoma can arise from endometriosis; however, it is distinct from other types of epithelial ovarian carcinoma in terms of its clinicopathological and molecular features. Cancer antigen 125 lacks the sensitivity and spe…

The aim of this study was to investigate the role of redox status in endometriosis and its malignant transformation. A search was conducted between 1990 and 2014 through the English language literature (online MEDLINE PubMed database) using…

OBJECTIVES: The aim of this review was to highlight recent advances in our understanding of the pathogenesis of malignant transformation of endometriosis. METHODS: This study reviewed the English-language literature concerning basic science…

We report the case of 23 year-old woman with OHVIRA syndrome (obstructed hemivagina and ipisilateral renal anomaly) discovered during management for right renal failure. Non-specific symptoms such as lower abdominal pain, dysmenorrhea, and …

Comparison of the transcriptomes and proteomes of the decidualization-specific genes that express high vs low levels of the eutopic and ectopic endometrium of women with endometriosis compared with controls, could be useful in understanding…

There is now accumulating evidence that endometriosis is a disease associated with an epigenetic disorder. Genomic imprinting is an epigenetic phenomenon known to regulate DNA methylation of either maternal or paternal alleles. We hypothesi…

PURPOSE: Much work has been carried out to investigate the genetic and epigenetic basis of endometriosis and proposed that endometriosis has been described as an epigenetic disease. The purpose of this study was to extract the imprinting ge…

PURPOSE: Endometriosis-associated pelvic pain appears due to persistent nociceptive stimulation, but the precise mechanisms remain poorly understood. METHODS: A search was conducted to screen and select articles from PubMed. MAIN RESULTS:…

Müllerian mucinous borderline tumors (MMBTs) usually arise from the ovary. The present report is the first case of primary uterine MMBTs associated with adenomyosis. A 51-year-old woman was referred to our hospital for a complex cystic and …

Endometriosis is a complex disease influenced by genetic, epigenetic and environmental factors. The aim of the present study was to describe genomic instability, genetic polymorphisms and their haplotype, epigenetic alterations associated w…

ObjectivesOvarian cancer is the most lethal gynecological malignancy in North America. Although survival rates are high when the disease is diagnosed at an early stage, this decreases exponentially in late-stage diagnoses. As such, there is…

Atypical endometriosis is reported to possess a precancerous potential attributed to premalignant changes characterized by cytological atypia and architecture proliferation. Moreover, the coexistence of atypical endometriosis and neoplasms …

Clear cell adenocarcinoma of the ovary (OCC) is a chemo-resistant tumor with a relatively poor prognosis and is frequently associated with endometriosis. Although it is assumed that oxidative stress plays some role in the malignant transfor…

Endometriosis is a common type of chronic inflammatory disease with an immunological background. In this review, we aimed to explore the contemporary literature on the infection and sterile inflammation that support the pathogenesis of endo…

A reduced response to progesterone in the eutopic endometrium with endometriosis and in endometriotic tissues is considered to be the underlying factor for endometriosis. CD10 is known to be expressed by endometrial and endometriotic stroma…

Uterine sarcoma is a rare neoplasm, accounting for only 5% of uterine malignancies. The pathogenesis of uterine sarcoma remains largely unknown, although recent basic science and pre-clinical animal models have provided a better understandi…

Endometriosis-associated ovarian cancers demonstrate substantial morphological and genetic diversity. The transcription factor, hepatocyte nuclear factor (HNF)-1β, may be one of several key genes involved in the identity of ovarian clear ce…

OBJECTIVES: Despite the high incidence of endometriosis, the etiology is poorly understood. Much work has been carried out to elucidate the genetic basis of endometriosis owing to the advent of genomic analysis and new network-based analysi…

BACKGROUND: The roles of molecular alteration such as genomic instability and cell survival are debated aspects of the pathogenesis of endometriosis. To review the contemporary literature on potential factors and their signaling pathways th…

Endometriosis is associated with pelvic pain and female infertility. Endometriosis induces inflammation and is vulnerable to oxidative stress damage. To update and summarize the literature concerning the mechanisms that serve to protect gen…

The association between endometriosis and malignant transformation has often been described in the medical literature. A search was conducted between 1966 and 2010 through the English language literature (online Medline PubMed database) usi…

Recently, the ARID1A gene has been identified as a novel tumor suppressor in ovarian clear cell carcinoma. The prognostic significance of the loss of ARID1A expression is not known. The current study was designed to evaluate whether ARID1A …

Two histologic types, clear cell carcinoma (CCC) and endometrioid adenocarcinoma (EAC), are the common histology in ovarian cancer patients who have associated endometriosis. However, both tumor types have distinct clinicopathological chara…
