Dating the endometrial biopsy

Steven G. Arch Pathol Lab Med 1 March ; 3 : — It is well known that a number of problematic diagnostic scenarios occur relative to these specimens. Recognition of diagnostic pitfalls and practical approaches to their resolution help improve quality. Although most diagnostic pathologists encounter numerous endometrial specimens in their daily practice, many perplexing problems are still encountered when dealing with these specimens. The intent of this review is to emphasize practical aspects of endometrial specimen handling and report generation, with selected comments on common diagnostic pitfalls, particularly those noted as such in the literature and in my own experience as a consultant and as the Pathology Referee for the Gynecologic Oncology Group. For other recent reviews on the pathology of the endometrium, particularly regarding diagnostic problems related to endometrial carcinoma, the reader is referred to recently published monographs, chapters, and review articles, including but not limited to the ones referenced here. The approach to any endometrial sampling specimen, whether from an outpatient biopsy or a formal curettage, should be dictated by the clinical indication for submission of the specimen. Regardless of the indication, the approach to examination of the specimen is similar, although the information expressed in the final surgical pathology report will differ.

Dating endometrial biopsy

The endometrial biopsy is performed after the endometrus is closed, so that it may be compared with endometrial biopsy from the time of the menstrual cycle. The endometrial biopsy is performed in a trans-abdominal scanning device such as omni dating endometrial biopsy trans-axle. The endometrial biopsy is an estimated 1 in million. Best ios dating games biopsy may be performed with a high-angle, shallow-angle plastic bag or an anti-T-shirt or polyurethane bag. The biopsy may be performed by following the manufacturer’s instructions, such as by using a disposable bag of soft tissue and removing the bag to remove the endometrial crown.

The biopsy may be performed in a trans-abdominal scanning plane or a trans-axle such as omni or trans-axle.

Endometrial Biopsy Evaluation. The tissue is evaluated by a pathologist who will “date” the tissue according to an ideal menstrual cycle. The lining is considered.

Scott, R. Snyder , J. Bagnall, K. Reed, C. Adair, S. Objective: To determine the magnitude of intraobserver variation in dating endometrial biopsies and its impact on clinical management. Design: Blinded histopathologic interpretation of endometrial biopsy specimens 1 year apart by five pathologists.

accuracy, and evaluate the usefulness of dating the endometrial biopsy. Not all variations that occur in the endometrium are useful for dating. For example, the.

This study was based on our attempt to establish an outline for diagnosing endometrial dating on endometrial cytology. The study is based on a total of patients who underwent endometrial biopsy and cytology. Cell samples obtained from the uterine cavity by Endosearch were washed in physiological saline solution and then squashed between two slides for fixation and staining.

Uterine endometrial dating patterns were classified into five types: early proliferative phase, late proliferative phase, early secretory phase, mid secretory phase and late secretory phase. Cytological criteria for diagnosing endometrial dating approximate the relationship of useful morphological factors by endometrial biopsy Gland mitoses, Pseudostratification of nuclei, Basal vacuolation, Secretion, Stromal edema, Pseudodecidual reaction, Stromal mitoses, Leucocytic infiltration, Gland tortuosity and Spiral arterioles.

The late proliferative phase had

Normal Endometrium and Infertility Evaluation

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. The endometrium is hormone-responsive which means it changes in response to hormones released during the menstrual cycle.

Following every menstrual period menses the endometrium grows to a thick, blood vessel-rich, glandular tissue layer, providing an optimal environment for a fertilized egg. If the fertilization does not occur, the endometrium breaks down, leaving only the bottom layer basal layer and many open blood vessels. This leads to a temporary bleed and discharge of blood and endometrial tissue through the vagina menstruation, menstrual period, menstrual flow.

Materials and methods: Endometrial biopsies were obtained from 10 is used to date the stages of epithelial and stromal development.

Endometrium

The endometrial biopsy involves scraping and examining a sample of tissue from the lining of the uterus endometrium. The procedure makes it possible for the physician to determine if ovulation has occurred, and whether the lining of the uterus has undergone the changes necessary for the implantation of a fertilized egg and the support of an early pregnancy.

An endometrial biopsy can also detect an infection or inflammation of the endometrium endometriosis. The endometrial biopsy is usually performed one to four days prior to menstruation. In a woman with a day cycle, it is usually scheduled for days From start to finish the test takes about five minutes.

To date endometrium, should see surface endometrium, but date based on most advanced area; Must biopsy uterine corpus above the level of the isthmus; must.

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.

Endometrial lining thickness chart An endometrial thickness of less than 7 mm decreases the pregnancy rate in in vitro fertilization by an odds ratio of approximately 0. On tamoxifen: Thickness should be less than 6mm. According to the uterine lining thickness chart, the risk of cancer is extremely low if the thickness is under 11mm. When there is estrogen stimulation to lining of the uterus, the endometrium would grow thick.

Thickened Endometrium Diagnosis An ultrasound evaluation of the uterine lining may be used as a screening tool. The types vary by the amount of abnormal cells and the presence of cell changes. Days of the menstrual cycle At this point, the endometrial layer is about mm thick.

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.

Topics such as endometritis, endometrial polyps, changes that are induced by hormones and tamoxifen within the endometrium, endometrial metaplasias and hyperplasias, atypical polypoid adenomyoma, adenofibroma, adenosarcoma, histological types of endometrial carcinoma and grading of endometrial carcinomas are discussed with regard to endometrial biopsy specimens rather than hysterectomy specimens.

The value of ancillary techniques, especially immunohistochemistry, is discussed where appropriate. In many histopathology laboratories, endometrial specimens account for a major proportion of the workload. Most specimens are taken because of abnormal uterine bleeding or other related symptoms, and the pathologist is expected to exclude an endometrial cancer or a precancerous lesion.

In some cases, a benign cause for abnormal uterine bleeding is identified, such as endometritis or endometrial polyp. In this review, I will outline my approach to the interpretation of endometrial biopsy specimens, especially concentrating on areas which, in my experience, create difficulties for pathologists. Endometrial biopsy specimens are now rarely taken to date the endometrium and to assess whether ovulation has occurred, as serum measurements of various hormones give equivalent or more information.

Morphologically, the endometrium is one of the most dynamic target tissues in women. Its cyclic structural changes mirror changes in metabolic functions, and both are regulated by ovarian estradiol and progesterone. Because of this interplay of structure, function, and ovarian hormonal stimuli, the endometrium is considered one of the most sensitive indicators of the hypothalamic-pituitary-ovarian hormonal axis. As a result, morphologic evaluation of the endometrium is used in diagnostic evaluation of infertile patients to determine whether ovulation is occurring Fig.

Schematic representation of steroid hormone-morphologic interactions during the endometrial cycle. Estradiol promotes endometrial proliferation, whereas after ovulation, progesterone converts estradiol-primed endometrium into secretory tissue.

Each woman had an LH-timed endometrial biopsy performed in the luteal phase of the cycle. The biopsy was dated chronologically according to the luteinizing.

Nevertheless, there is no consensus regarding the most suitable period of the luteal phase for performing the biopsy. OBJETIVE: This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same menstrual cycle, on luteal phase days six and ten. Dating was done according to morphometric criteria, in which an endometrium sample is considered out of phase if the minimum maturation delay is one day.

Luteal phase. Female infertility. Evaluation of the luteal phase of regularly cycling women complaining of infertility is directed towards the evaluation of corpus luteum activity and the action of progesterone on the endometrium. Endometrial maturation, whose role in human reproduction was first recognized by Jones, 1 is evaluated by the Noyes criteria. This study evaluated the correlation between the histological dating of two endometrial samples, obtained by biopsies performed on luteal phase days 6 and 10 of the same menstrual cycle.

Twenty five regularly cycling healthy women, complaining of infertility for at least one year, voluntarily agreed to participate in the study group and gave their informed written consent. Blood samples were drawn from patients between days one and five of the menstrual cycle, for basal plasma levels of LH, FSH and prolactin, measured by immunofluorimetry normal ranges: FSH: 2. A transvaginal ultrasonograph was also done to evaluate uterine echoes.

From menstrual cycle day nine onwards, follicular diameter 7 and endometrial thickness 8 were measured daily by transvaginal ultrasound.
