My approach to the interpretation of endometrial biopsies and curettings

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.

Conclusion(s): The ERA is more accurate than histologic dating and is a completely reproduc- ible method for the diagnosis of endometrial.

Engman is a fellow in reproductive endocrinology and infertility, University of Connecticut School of Medicine, Farmington, Conn. Disagreement about the cause, true incidence, and diagnostic criteria of this condition makes evaluation and management difficult. Here, 2 physicians dissect the data and offer an algorithm of assessment and treatment. Despite scanty and controversial supporting evidence, evaluation of patients with infertility or recurrent pregnancy loss for possible luteal phase deficiency LPD is firmly established in clinical practice.

Although observational and retrospective studies have reported a higher incidence of LPD in women with infertility and recurrent pregnancy losses than in fertile controls, 1 – 4 no prospective study has confirmed these findings. Furthermore, studies have failed to confirm the superiority of any particular therapy. Once considered an important cause of infertility, LPD has become the subject of debate, with some experts questioning its very existence.

Hormonal Pathology of the Endometrium

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.

Nothnick, Robert N. Taylor and Monique Monard. This chapter will explore the latter phase of the menstrual cycle focusing on the secretory phase of the endometrium. In particular, focus will be on the mid-secretory endometrium and appropriate markers and hormonal environment for successful implantation. This will be put in the context of the luteal phase of ovulation and the hormonal support that progesterone provides.

We will also review pathologic states, such as endometriosis and related progesterone resistance, which affect mid-secretory phase and implantation. Finally, we will provide a detailed review of the literature on what the current state of knowledge is regarding receptivity and the microenvironment of the mid-secretory endometrium which is essential to implantation.

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. Although guidelines and checklists are available for the examination and reporting of endometrial specimens involving carcinomas, 11 , 12 I am unaware of a similar effort related to the reporting of all endometrial biopsy or curettage specimens, and have attempted to provide some guidelines in Table 1.

It should be emphasized that this checklist was designed by me rather than by a committee, and I am sure that other pathologists reviewing it will be able to provide useful additions, alterations, and deletions. A determination that applies to endometrial sampling specimens, regardless of the clinical indication, is the evaluation of adequacy, although an unremarkable specimen that is adequate for one indication may not necessarily be sufficient for another.

In Table 1 , I present some suggestions on reporting or at least thinking about this evaluation. Obviously, the amount of endometrial tissue present in a specimen will depend on a number of factors, including the amount of endometrium present in the uterus less in atrophy, more in hyperplasias and most carcinomas, and so forth , the type of procedure performed curettage is expected to yield more endometrial tissue than the usual outpatient biopsy , and the experience and competence of the operator.

During the proliferative phase, daily morphologic alterations are not sufficiently obvious to permit accurate dating. At the secretory phase the daily changes during.

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.

Endometrial samples were collected from them in two to four menstrual cycles at 2 and 7 days post first significant rise in blood LH. Separate endometrial glands and stroma populations were obtained by laser microdissection.
