Chapter 17 – Uterus Flashcards Preview
The uterus is a hollow muscular organ located in the female pelvis between the urinary bladder and the rectum the lower end of the large bowel. The upper part of the uterus fundus is attached to the fallopian tubes while the lower part is connected to the vagina through the uterine cervix. Functions of the uterus include nurturing the baby, and holding it until the baby is mature enough for birth.
Small samples of tissue can be removed from the endometrium by several different techniques with the two most common being endometrial biopsy and endometrial or uterine curetting.
Endometrium in pathology •Basic questions –Why endometrial sampling? Endometrial dating • Interpreting the cycle based on histomorphology of The orientation and outline of proliferative phase glands and their.
There are two predominant isoforms of COX enzymes, COX-1, which is constitutively expressed in many cell types and COX-2, which is induced by factors including cytokines and tumour promoters Kniss PGI 2 elicits its effects on target cells by interaction with its G protein-coupled receptor IP receptor , which has a typical seven-trans-membrane structure Narumiya et al. Maximal expression and signalling of these receptors are detected during the mid-late proliferative phase of the menstrual cycle.
In contrast, little is known of the expression pattern and function of the IP receptor in human endometrium, although PGIS and IP receptor expression have been demonstrated in pregnant and non-pregnant myometrium Moonen et al. Moreover, PGI 2 is known to act as a smooth muscle relaxant Wilhelmsson et al. The effects of PGI 2 on platelet aggregation and vascular tone have outlined its potential role in menstruation Baird et al.
This is supported by observations of elevated PGI 2 levels in uterine venous blood during menstruation as compared with other phases of the menstrual cycle Goodfellow et al. Moreover, PGI 2 synthesis is increased in women suffering from heavy menses compared with those who show normal blood loss Smith et al. It has also been suggested that menstrual disorders can be the result of a shift in the ratio of different prostaglandins. The objectives of the present study were to investigate the expression of PGIS the terminal enzyme responsible for the generation of PGI 2 and IP receptor in non-pregnant human endometrium and myometrium across the menstrual cycle.
A better understanding of IP receptor signalling and function in the human endometrium may ultimately lead to the development of novel therapies in the treatment of menstrual disorders that may be associated with elevated PGI 2 synthesis.
Endometrium acquires structural and functional competence for embryo implantation only during the receptive phase of menstrual cycle in fertile women. The database was used to identify the Receptivity Associated Genes RAGs which display the similar pattern of expression across different investigations. JAr spheroid attachment assays were carried out to assess the functional significance of two RAGs.
HGEx-ERdb is a catalogue of 19, genes, reported for their expression in human endometrium. Further genes were identified as the RAGs.

Dating endometrium, implantation
In an era of ever-increasing knowledge of the symphony of physiologic events surrounding ovulation, fertilization, and implantation of human oocytes and embryos, born out of previously unimaginable technologic advancement, few scientific puzzles have been explored more times than the entity synonymously known as luteal phase insufficiency, inadequacy, defect, or deficiency. This chapter uses the term luteal phase deficiency LPD. Although it successfully can be argued that LPD is the most common abnormality of the menstrual cycle, its significance as a disease entity is shrouded in controversy over its incidence, means of diagnosis, and legitimacy of treatment.
Since the first formal description of LPD in as a possible cause of infertility and recurrent miscarriage by Jones, 1 innumerable investigations have been undertaken in an effort to verify its existence or to characterize its pathophysiology, diagnosis, and treatment. The consensus of the literature is that LPD does exist and that its cause is multifactorial e.

The endometrium is typically biopsied because of abnormal bleeding. Endometrial hyperplasia and endometrial carcinoma are dealt with in separate articles. An overview of gynecologic pathology is in the gynecologic pathology article.
luteum is a – cm round yellow structure with lobulated outlines and a cystic center. Morphologic criteria for the dating of the corpus luteum have been reported in association with endometrial adenocarcinoma; in some of these.
Progesterone secretion inhibits endometrial proliferative activity and induces secretory activity. In recapitulation, dating the endometrium during the first week of luteal activity depends primarily upon recognition of changes occurring in gland epithelium; namely, mitosis, pseudostratification, basal vacuolation, and secretion.
Figure 1 summarizes the criteria most useful in endometrial dating. This phase is variable in length, and day-by-day changes are not. However, the intra- and interobserver variability inherent in dating the product of the endometrial biopsy-the endometrium -has led to the current situation, in which ,. The pathologist can improve this to 2—3 days, however, by acquiring expertise in endometrial dating all cases of normal endometria are to be dated regardless of.

Metaplasias to Nonspecific Cell Types. Atypical Polypoid Adenomyoma. Infections of the gynecologic tract are relatively common, and cause an enormous health impact. Symptomatic infections are most commonly diagnosed based on the clinical examination and basic laboratory studies, and, as such, a tissue biopsy is generally not needed.
An unknown fraction of STDs lead to asymptomatic infections, or to signs that are not recognized to be related to infection, such as dysfunctional uterine bleeding.

Philadelphia, PA: Elsevier Benign endometrial proliferations mimicking malignancies: a review of problematic entities in small biopsy specimens. Benign proliferations that mimic malignancies are commonly encountered during the course of assessment of small and fragmented endometrial samples.
Although benign, endometrial epithelial metaplasias often coexist with premalignant or malignant lesions causing diagnostic confusion. The difficulty with mucinous metaplasia lies in its distinction from atypical mucinous glandular proliferations and mucinous carcinomas, which are associated with significant interobserver variability.
Papillary proliferation of the endometrium is commonly associated with hormonal drugs and endometrial polyps and is characterised by papillae with fibrovascular cores covered by epithelial cells without cytologic atypia. They are classified into simple or complex papillary proliferations depending on the architectural complexity and extent of proliferation.
