Secretory Phase and Implantation

For example, a person may have a thinned uterine lining as the result of a surgery on the uterus or a uterine infection. References — Jacobs I et al. The action of oestrogen in the follicular phase leading up to ovulation, stimulates the lining to develop until it shows this 3 layer appearance ultrasound from Dr Sher, SIRM , which has been associated with better implantation rates in frozen embryo cycles. As a woman’s age increases, her risk of cancer increases at each endometrial thickness measurement. Casey Younkin: 0. The endometrium is usually best seen on endovaginal scans. There is some debate about “how thin is too thin”, as well as to “how thick is too thick”.

The endometrial tissue is a sensitive target for steroid sex hormones and is able to modify its structural characteristics with promptness and versatility.

This article discusses briefly endogenous hormonal effects cyclic changes, luteal phase defect, unopposed estrogen effect and describes the histologic patterns encountered in the most commonly used hormone therapies: oral contraceptives, ovulation stimulation, hormone replacement therapy, and antitumoral hormone therapy. Oral contraceptives exert a predominant progestational effect on the endometriun, inducing an arrest of glandular proliferation, pseudosecretion, and stromal edema followed by decidualized stroma with granulocytes and thin sinusoidal blood vessels.

Prolonged use results in progressive endometrial atrophy. Ovulation induction therapy accelerates the maturation of the stroma and is often associated with a discrepancy between early secretory glands and an edematous or decidualized stroma with spiral arterioles. Hormone replacement therapy with estrogen alone may result in continuous endometrial proliferation, hyperplasia, and neoplasia. Progesterone therapy for endometrial hyperplasia and neoplasia induces glandular secretory changes, decidual reaction, and spiral arterioles.

Glandular proliferation is usually arrested, but neoplastic changes may persist and coexist with secretory changes. Lupron therapy produces a shrinking of uterine leiomyomas by accelerating their hyaline degeneration, similar to that in postmenopausal involution. It generally produces endometrial atrophy.

These lesions usually appear as localized solitary nodule with a sessile or pedunculated base and colour varying from red, purplish, or pink, depending on the vascularity of the lesion.

Chapter 8 Pathology of Reproductive Endocrine Disorders. An appreciation of the relationship between form and function is important for understanding of female reproduction. An awareness of histologic changes associated with both the normal ovulatory cycle and reproductive diseases allows the physician a better understanding of pathophysiology and potential treatment. This chapter begins with an examination of the histologic changes in the endometrium associated with a normal ovulatory cycle.

This is followed by an illustrated survey of common gynecologic diseases of the reproductive organs that are most likely to present to the reproductive surgeon. The endometrium is functionally divided into two layers: the basalis and the functionalis. Both layers are composed of stroma and glands. The stroma is composed of stromal cells, vessels, and white blood cells thought to be lymphocytes or macrophages. Cyclic changes occur in both endometrial glands and stroma in response to a changing endocrine environment.

Histologic dating of the endometrium: Accuracy, reproducibility, and practical value

Background: Abnormal uterine bleeding AUB is a common gynecological complaint associated with considerable morbidity and significantly affects the patient’s family, personal and social life. The aim of the study was to analyze the histomorphological patterns of endometrium in patients presenting with AUB and also to determine the incidence of AUB in various age groups. Materials and Methods: This is a prospective study, conducted in the Department of Pathology, in a tertiary care teaching hospital, Mangalore from October till date.

All cases of AUB with a probable endometrial cause were included in the study. Analysis was done in the form of percentages and proportions and represented as tables where necessary.

HCC, ovarian/endometrial cancer, lung cancer, breast cancer, prostate cancer Oct studies performed to date have not demonstrated geriatric-specific problems NSCLC of adenocarcinoma tumour histology after first-line chemotherapy.

A major proportion of the workload in many histopathology laboratories is accounted for by endometrial biopsies, either curettage specimens or outpatient biopsy specimens. The increasing use of pipelle and other methods of biopsy not necessitating general anaesthesia has resulted in greater numbers of specimens with scant tissue, resulting in problems in assessing adequacy and in interpreting artefactual changes, some of which appear more common with outpatient biopsies.

In this review, the criteria for adequacy and common artefacts in endometrial biopsies, as well as the interpretation of endometrial biopsies in general, are discussed, concentrating on areas that cause problems for pathologists. An adequate clinical history, including knowledge of the age, menstrual history and menopausal status, and information on the use of exogenous hormones and tamoxifen, is necessary for the pathologist to critically evaluate endometrial biopsies.

It involves multiple disciplines, including pathology, physiology, internal medicine, pediatrics, and laboratory medicine. Present on actively proliferating cells; essential for iron transport into proliferating cells benign and malignant Iron bound apotransferrin binds CD71, is internalized to endosome, which becomes acidic; the acidic pH leads to iron release, iron-free apotransferrin is returned to cell surface; surface pH causes iron-free apotransferrin to lose affinity for CD71, is released into circulation, allowing a new cycle to begin.

It is the degree of atypia and clinical aggressiveness that distinguishes the two subtypes. The B cell marker CD19 is absent. Detection of a B-cell population coexpressing CD22, CD11c, and CD25 is useful in establishing a diagnosis of hairy cell leukemia when used in conjunction with morphology and cytochemistry. Pagetoid reticulosis PR , also known as Woringer-Kolopp disease, is a form of cutaneous T-cell lymphoma that demonstrates striking epidermotropism on histologic examination.
