Endometrioid intraepithelial neoplasia (EIN) is a preinvasive precursor of endometrial carcinoma, yet its recognition in secretory-phase endometrium remains diagnostically challenging. Current criteria for EIN diagnosis do not account for f…

Endometrioid borderline tumors (EBTs) and seromucinous borderline tumors (SMBTs) are rare ovarian neoplasms with distinct histologic features. However, the molecular profiles of EBTs and SMBTs remain incompletely characterized. We performed…

Adenomyosis is a common gynecological disorder that causes heavy menstrual bleeding and chronic pelvic pain. Progestin-based therapy is widely used for long-term management, but irregular uterine bleeding frequently occurs and severely affe…

BACKGROUND: Ovarian ectopic pregnancy (OEP) is a rare and life-threatening condition that is typically diagnosed post-rupture. Its diagnosis and management become more complex when it is concurrent with ovarian endometrioma, as the latter m…

BACKGROUND: This network meta-analysis (NMA) aimed to explore the impact of Non-pharmacological therapies (NPT) on alleviating primary dysmenorrhea (PD) symptoms and assess the effectiveness differences among various NPT. METHODS: We searc…

RESEARCH QUESTION: What are the lipidomic alterations in the myometrial tissue from adenomyotic lesions? DESIGN: This was a two-centre, prospective, observational study conducted between July 2023 and June 2024. Forty-four premenopausal pa…

Rising rates of infertility have stimulated interest in dietary supplements to improve oocyte quality through mitochondrial function, antioxidant activity, and epigenetically regulated metabolic pathways. Mitochondria provides adenosine tri…

RATIONALE: Sepsis following hysteroscopy is an rare complication, with current evidence suggesting that routine prophylactic antibiotic administration may not be warranted. However, this does not imply that we should disregard vigilance reg…

STUDY OBJECTIVES: Polycystic ovary syndrome (PCOS) confers a high risk of obstructive sleep apnea (OSA). Here we investigated the effect of OSA on first in vitro fertilization (IVF) cycle metrics and outcomes in patients with PCOS. METHODS…

The mechanism involved in the pathogenesis of endometriosis is poorly understood. The purpose of this study is to identify key deubiquitinating enzymes (DUBs) for endometriosis diagnosis and elucidate the possible mechanism, offering novel …

Endometriosis is a common condition, with the ovary being the most common anatomic site. Endometriosis-particularly in the ovary-is associated with a risk of malignant progression, with a histologic spectrum of lesions from benign to malign…

Dysbiosis of the female reproductive tract is closely associated with gynecologic diseases. Here, we aim to explore the association between dysbiosis in the genital tract and uterine fibroids (UFs) to further provide new insights into UF et…

This study aims to characterize the cell atlas of the epididymis derived from a 46,XY disorders of sex development (DSD) patient with a novel heterozygous mutation of the nuclear receptor subfamily 5 group A member 1 (NR5A1) gene. Next-gene…

Abstract Background Polypoid endometriosis (PEM) is rare benign tumors with morphological features resembling malignant tumors. We aimed to analyze the clinicopathological features and outcomes of patients with PEM, and compare them to case…

There is an ongoing debate about the value of animal research in psychiatry with valid lines of reasoning stating the limits of individual animal models compared to human psychiatric illnesses. Human depression is not a homogenous disorder;…

The diagnosis of atypical hyperplasia/endometrioid intraepithelial neoplasm (AH/EIN) within endometrial polyps (EMPs) often poses a diagnostic conundrum. Our previous studies demonstrated that a panel of immunohistochemical (IHC) markers co…

We report a case of stage IVB ovarian clear cell carcinoma in a 35-year-old female with a long-standing history of biopsy-proven pelvic and thoracic endometriosis. At the time of her ovarian cancer diagnosis, her tumors were found to be iso…

The expression of the SRY-Box Transcription Factor 15 (Sox15) is reduced by DNA methylation, and its progression is suppressed within numerous tumors. However, its effect on hepatocellular carcinoma (HCC) remains unknown. In the present wor…

Clinical application of exogenous hormone as a method of contraception and/or treatment of various gynecologic disorders is exceedingly common. Unfortunately, the concurrent use of these agents also complicates the interpretation of patholo…

BACKGROUND: Primary ovarian serous carcinomas (OSC) with extensive squamous differentiation is a rare, and histological diagnostic criteria and biological behavior have not been fully established. We present an extremely rare case of primar…

The endometrium is unique as an accessible anatomic location that can be repeatedly biopsied and where diagnostic biopsies do not extirpate neoplastic lesions. We exploited these features to retrospectively characterize serial genomic alter…

PURPOSE: To investigate the relationship between dedifferentiated endometrioid carcinomas with neuroendocrine differentiation and mismatch repair deficiency. PATIENTS AND METHODS: The clinicopathological records and samples of three patien…

Read the full review for this Faculty Opinions recommended article: Single-cell RNA sequencing of oocytes from ovarian endometriosis patients reveals a differential transcriptomic profile associated with lower quality.

Rationale: Abnormal Wnt/β-catenin signaling in the endometrium can lead to both embryo implantation failure and severe pathogenic changes of the endometrium such as endometrial cancer and endometriosis. However, how Wnt/β-catenin signaling …
