Total laparoscopic hysterectomy (TLH) is a widely accepted minimally invasive procedure for benign gynecologic diseases. Transvaginal retrieval avoids additional abdominal incisions but may be technically challenging in nulliparous women be…

Uterine artery embolization is a treatment option for symptomatic uterine myomas. The Japanese Society of Interventional Radiology Guideline Committee developed guidelines for uterine artery embolization procedures for symptomatic uterine m…

Mesonephric-like adenocarcinoma is a rare neoplasm of the uterine corpus and ovary. Unlike prototypical mesonephric adenocarcinoma of the uterine cervix, which is considered of Wolffian origin, recent evidence suggests that mesonephric-like…

BackgroundSince the human papillomavirus vaccines do not eliminate preexisting infections, nonsurgical alternative approaches to cervical intraepithelial neoplasia (CIN) have been required. We previously reported that FOXP4 (forkhead box tr…

Ezrin-radixin-moesin-binding phosphoprotein 50 (EBP50) is a scaffold protein that is required for epithelial polarity. Knockout (KO) of membranous EBP50 (Me-EBP50) in ovarian clear cell carcinoma (OCCC) cells induced an epithelial-mesenchym…

Abstract Aim Peritoneal endometriosis is a chronic inflammatory disease particularly associated with macrophages. Of note, adipose tissues with fibrotic changes in the context of peritoneal endometriotic lesions are often observed during su…

Periodic myometrial contraction is one of the important uterine functions to achieve embryo implantation and parturition. Although it is well-known that the mammalian myometrium is composed of longitudinal (outer) and circular (inner) layer…

IntroductionWe have reported previously that fecal DNA testing of TWIST1 methylation in combination with the fecal immunochemical test for hemoglobin (FIT) (combination test) is useful for colorectal neoplasia screening. In this study, usin…

Introduction . The canal of Nuck is an embryological remnant of the peritoneal pouch that extends into the labium majus of women. Hydrocele is the most common presentation, but only a small number of cases are reported in association with e…

When the presence of endometriotic lesions are not evident by hematoxylin and eosin staining, CD10 is used to highlight and confirm the presence of endometriotic stroma. However, CD10 is not specific only to the endometrial stroma but is al…

In cases of extragenital endometriosis or microscopic endometriosis lesions, pathological diagnosis can be challenging because endometriotic stroma and glands represent only a minor component of fibrotic endometriotic lesions. For better ac…

We focused on specific molecular events during the development of endometriosis-associated ovarian endometrioid carcinoma (OEmCa) and ovarian clear cell carcinoma (OCCCa). Alterations in β-catenin (encoded by CTNNB1) and microsatellite inst…

BackgroundA majority of women from all cultures and socioeconomic levels experience myriad symptoms known as premenstrual syndrome during the days prior to menstruation. The present study investigated commonly reported symptoms in the preme…

When the presence of endometriotic lesions are not evident by hematoxylin and eosin staining, CD10 is used to highlight and confirm the presence of endometriotic stroma. However, CD10 is not specific only to the endometrial stroma but is al…

BACKGROUND: Expression of Nodal, a member of the TGF-β superfamily, is commonly absent in differentiated tissues, while its re-expression occurs in a variety of human malignancy. However, little is known about its involvement in ovarian tum…

In cases of extragenital endometriosis or microscopic endometriosis lesions, pathological diagnosis can be challenging because endometriotic stroma and glands represent only a minor component of fibrotic endometriotic lesions. For better ac…

BackgroundThe left-right determination factor (LEFTY) is a novel member of the TGF-β/Smad2 pathway and belongs to the premenstrual/menstrual repertoire in human endometrium, but little is known about its functional role in endometrial carci…

A supernumerary ovary is an exceedingly rare disorder, in which the structure containing ovarian tissue is located at some distance from the normally placed ovary. 16 cases of endometriosis or tumors originating in a supernumerary ovary hav…

ObjectiveTo evaluate the effect of dienogest (DNG) in preventing the occurrence of pain and endometriomas after laparoscopic resection of uterosacral ligaments (USLs) with deep infiltrating endometriosis (DIE).Study designThis retrospective…

To identify proteins involved in ovarian clear cell carcinoma (OCCCa), shotgun proteomics analysis was applied using formalin-fixed and paraffin-embedded samples of ovarian carcinoma. Analysis of 1521 proteins revealed that 52 were differen…

•Endometrial stromal sarcoma disseminated after morcellation•Complete remission of pelvic recurrence was achieved by oophorectomy.•Laparoscopic confirmation of remission of recurrent disease.

OBJECTIVES: We focused on the differences in molecular mechanisms in the early stages of endometriosis-associated ovarian endometrioid carcinoma (OEMCa) and ovarian clear cell carcinoma (OCCCa). METHODS: Alterations in the β-catenin and PIK…

Hepatocyte nuclear factor-1β (HNF-1β) is a transcriptional factor that has an important role in endometriosis-ovarian clear cell carcinoma (OCCC) sequence by modulating cell kinetics and glucose metabolism. However, little is known about th…

IntroductionHydrocele of the canal of Nuck is a rarely encountered entity. We report a case underwent laparoscopic totally extraperitoneal (TEP) treatment for a hydrocele of the canal of Nuck extending in the extraperitoneal space mainly.Pr…

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 …
