Uterine fibroids (UF) are the most common benign tumor of the female reproductive tract. The aim of this study was to explore the role of lipopolysaccharide (LPS)-induced activation of TLR4/NF-κB signaling pathway on stromal fibroblasts in …

Benign lymph node inclusions are commonly encountered during surgery for gynecologic neoplasms and are potential mimics of metastatic tumor. The presence of mesothelial cell inclusions in pelvic lymph nodes is extremely rare. We report the …

A 67-year-old woman who was presented to the gynecologist with a two-month history of heavy vaginal bleeding, after an excisional biopsy of vulvar mass, was diagnosed with the right colon adenocarcinoma metachronous metastasis to the vulva.…

Emerging evidence showed that miRNA dysregulation is involved in the development of endometriosis and may contribute to pathological process of endometriosis associated ovarian cancer (EAOC). miR-191 is one of the most differentially expres…

We previously reported that miR-199a suppressed the invasiveness of endometrial stromal cells (ESCs) by targeting IkappaB kinase beta (IKKβ). This study was to investigate the role of miR-199a in the angiogenic potential of ESCs under hypox…

OBJECTIVE: To test the immunohistochemical staining pattern of some mismatch repair (MMR) system proteins in endometriotic tissue (ET) and eutopic endometrium. METHODS: This was a retrospective study conducted at the Pathology and Obstetri…

We report here an unusual presentation of peritoneal endometriosis with smooth muscle metaplasia as multiple protruding masses on the lateral pelvic wall. Smooth muscle metaplasia is a common finding in rectovaginal endometriosis, whereas i…

Gastrointestinal stromal tumors (GISTs) have a rather wide morphologic spectrum. Here, we report a rare variant plexiform GIST in gastric antrum. Microscopically, the tumor showed plexiform or multinodular growth pattern, proliferation of s…

Primary adenosquamous carcinoma of the liver is a rare subtype of cholangiocarcinoma. Adenosquamous carcinoma, which consists of both adenocarcinoma and squamous cell carcinoma components. A 73-year-old woman was admitted to our hospital wi…

AIMS: Musashi-1, a RNA-binding protein, is suggested to be a cancer stem cell-related marker; its high level of protein expression is reported to be associated with high histological grade in some tumors. The aim of this study was to invest…

Endometriosis involving intestinal mucosa is relatively uncommon. It poses a diagnostic challenge for clinicians and pathologists. We herein report a case of colonoscopic specimen revealing rectal mucosal endometriosis. A 39-year-old woman …

OBJECTIVE: The aims of this study are to detect levels of AGEs and RAGE and SNPs for RAGE in vaginal tissues of women with POP and rats in a repair location, and to explore the relationship between AGEs-RAGE pathway and POP. METHODS: This …

Hyperlipidemic pancreatitis (HP) is a serious inflammatory disease with very high mortality and multiple organ injuries including renal injury. Rosiglitazone (Ros), an agonist of peroxisome proliferator activated receptor-γ (PPAR-γ), was re…

Recently, increasing evidence has shown that uterus preservation is beneficial for pelvic organ prolapse (POP) patients, both physiologically and psychologically. However, the preoperative indicators for uterus preservation have rarely been…

OBJECTIVES: The objective of the present study was to evaluate whether fibrotic markers and endometrial stem cell markers were abnormal expressed in endometrium of intrauterine adhesions and a female mouse model for intrauterine adhesions. …

Vascular endothelial growth factor (VEGF) receptor-2 plays an essential role in angiogenesis, and it also expressed in the glandular epithelium and stromal cells of ectopic endometrium. Cediranib is a protein tyrosine kinase inhibitor that …

Advanced abdominal pregnancy is rare. The low incidence, high misdiagnosis rate, and lack of specific clinical signs and symptoms explain the fact that there are no standard diagnostic and treatment options available for advanced abdominal …

This study measured the antioxidant activity of follicular fluid (FF) in infertile patients and assessed its possible correlation between ovarian stimulation and pregnancy outcomes. Samples from 191 infertile patients undergoing in vitro fe…

Ovarian yolk sac tumors (YSTs) usually occur in the young women and have been rarely documented in perimenopausal and postmenopausal women. The different age distribution supposes their complex nomenclature and histogenesis. We report a cas…

CONTEXT: In the last two decades, a color based concept of disease activity in peritoneal endometriosis has been in use in the clinical context, with red lesions being considered active and black or white lesions being interpreted as less a…

Endometriosis, diagnosed with ectopically implanted endometrial stromal cells (ESC) and epithelial cells to a location outside the uterine cavity, seriously threaten the quality of life and reproductive ability of women, yet the mechanisms …

Angiogenesis is an important pathogenesis of Endometriosis. Vascular endothelial growth factor C (VEGF-C) is one of the most important factor in the regulation of both normal and abnormal angiogenesis. Anti-angiogenic treatment of endometri…

Hilus cell heterotopia is the presence of normal hilus cells in an abnormal site. It is rare and there are only a few case reports or case series. It has been reported in the fimbrial stroma of the fallopian tube, paratubal cyst wall and be…

In the peritoneal fluid, macrophages and their secretory cytokines are essential for endometriosis, but the factors that favor their involvement in the endometriosis-associated inflammatory response are still elusive. Given the anomalous ex…

OBJECTIVE: Mouse bone marrow mesenchymal stem cells (BMSCs) have been demonstrated to differentiate into female endometrial epithelial cells (EECs) in vivo. Our previous studies demonstrated that BMSCs can differentiate in the direction of …
