Endometriosis is a common chronic disease characterized by growth of the endometrial gland and stroma outside the uterus. Symptoms affect physical, mental and social well-being. Extrapelvic location of endometriosis is very rare. Abdominal wall endometriosis occurs in 0.03%-2% of women with a previous cesarean section or other abdominopelvic operation. The leading symptoms are abdominal nodular mass, pain and cyclic symptomatology. The number of cesarean sections is increasing and so is the incidence of abdominal wall endometriosis as a potential complication of the procedure...

BACKGROUND: Endometriosis is a common, benign, and estrogen-dependent disease characterized by pelvic pain and infertility. To date, the pathogenesis of endometriosis remains unclear. Recent studies have demonstrated that noncoding RNAs, including microRNAs and long noncoding RNAs, play important roles in the development of endometriosis. METHODS: Expression profiling of miRNAs in endometrial tissue was characterized using microarrays. The most differentially expressed miRNAs were confirmed using quantitative reverse transcriptase-polymerase chain reaction analysis in additional ectopic endometrial (n = 27) and normal endometrial (n = 12) tissues...

BACKGROUND: Although metastatic disease is commonly seen in high grade carcinomas of gynecologic origin, it also occurs in low to intermediate grade endometrioid carcinomas (LGEMCAs), and may even be the primary presentation of disease. Tissue confirmation is necessary to guide therapy, but performing biopsies might not always be feasible or practical. In such instances, fine needle aspiration (FNA) is a safe and efficient alternative. No comprehensive series describing the cytomorphologic features of metastatic LGEMCA on FNA samples has been published...

Housekeeping genes (HKG) are presumed to be constitutively expressed throughout tissue types but recent studies have shown they vary with pathophysiology. Often, validation of appropriate HKG is not made. There is no consensus on which HKGs are most stably expressed in endometrial tissue so this study aimed to identify the most stable HKG in the endometrium of women with recurrent implantation failure (RIF) and recurrent miscarriages (RM). Inclusion criteria were women between 25-45 years (n = 45) suffering recurrent miscarriage (RM), recurrent implantation failure (RIF) or fertile controls...

Cytochrome P450 enzymes are required for the synthesis of cholesterol and steroid hormones. Cytochrome P450 oxidoreductase (POR) donates electrons to microsomal cytochrome P450 enzymes. POR deficiency (PORD) is a rare autosomal recessive disease. In patients with PORD, steroid hormone synthesis is disrupted, which can cause infertility. The objective of this study was to report on a case of in vitro fertilization-frozen embryo transfer (IVF-FET) in a patient with PORD. The patient's hormone (i.e. 17α-hydroxyprogesterone) and electrolyte levels were within normal ranges ordinarily...

OBJECTIVE: Preoperative or intraoperative risk assessment models are used to stratify patients with endometrial carcinoma to lymphadenectomy. Our aim was to determine whether preoperative analysis of L1 cell adhesion molecule (L1CAM) can improve risk assessment. METHODS: Immunohistochemical L1CAM staining was performed on endometrial biopsies of 241 patients and paired hysterectomy samples of 75 patients. Risk assessment models based on preoperative histologic type and grade, myometrial invasion, and/or tumor diameter and alternative models incorporating preoperative L1CAM were compared with regard to their capability of predicting lymph nodal or distant metastasis...

Endometrial cancer is the most common gynecological malignancy in the developed world. It is the fifth most common cancer and accounts for 4.8% of all cancers in women. Long intergenic non-coding RNAs (lincRNAs), a subclass of long non-coding RNAs, are pervasively transcribed throughout the human genome. OBJECTIVE: LincRNA expression patterns in endometrial cancer compared to normal healthy tissue are poorly characterised. In this study, the lincRNA transcriptome of endometrial cancers and adjacent normal endometrium from the same patients was sequenced and compared with transcriptomes of other gynaecologic malignancies including ovarian and cervical cancers...
