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.

Thus, studies that clearly delineate which histologic parameters serve as the greatest source of disagreement for pathologists provide a valuable framework for further refinement of the criteria for endometrial dating. Meanwhile, continued use of the criteria of Noyes et al for endometrial dating is recommended until more precise modalities for assessing the adequacy of endometrial maturation are available.

The lining epithelium contains glycogen rich subnuclear vacuoles in the early secretary phase. The vacuoles will be supranuclear in midsecretary phase. In the late secretary phase, the glands are saw toothed and serrated with luminal secretions.

Conclusion s : Traditional histologic dating of the endometrium has remained the gold standard for nearly 50 years. The potential effect of this variation on the diagnosis of luteal phase defects LPDs and resulting clinical management was also determined. The magnitude of the variation was not affected by whether the biopsy specimen was obtained in the mid or late luteal phase, the degree of lag between the dating and subsequent menses, or the presence of an LPD.

and correlate it with the histological dating of the endometrial tissue. Endometrial samples were timed histologically according to Noyes’.

Metrics details. Herein we measure the expression of beta3 integrin subunit, a well-known implantation marker, in women with or without RPL and correlate it with the histological dating of the endometrial tissue. Type I beta3 negative in an out-of-phase endometrium and Type II defect beta3 negative in an in-phase endometrium were also analysed. The mean SD age in controls was lower compared to cases [ The median range expression of beta3 integrin in controls and cases was 1.

Women with unexplained RPL had significantly reduced integrin expression compared to controls. Our findings underline the need for further molecular analysis of endometrial tissue in affected women. These include embryonic factors, like poor quality embryos with or without karyotype abnormalities, as well as maternal factors, such as uterine malformations, general maternal infections, as well as local inflammation [ 2 ], hormonal abnormalities, immunogenic abnormalities like thyroid antibodies, cardiolipin antibodies or antinuclear antibodies , genetic imbalances and thrombophilic diseases [ 3 ].

However, when none of these factors are evident, the recurrent pregnancy losses are classified as idiopathic, because the underlying mechanisms are not well understood. The functional expression of endometrial genes and proteins have been examined, because they compromise the endometrial microenviroment and may therefore contribute to an abnormal foetal-maternal interaction, resulting in pregnancy failure [ 4 ].

Furthermore synchronisation between embryonic development and endometrial decidualisation is found to be essential for adequate implantation [ 5 ]. Many authors have studied the embryo-endometrium interface in order to elucidate the pregnancy failure [ 6 , 7 ]. Global gene expression analysis [ 8 , 9 ] has determined the adequate endometrial gene and protein expression during the short endometrial receptive stage in the mid-secretory phase, the so-called window of implantation WOI [ 10 ].

Hormonal Pathology of the Endometrium

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.

This study evaluated the correlation between the histological dating of two endometrial biopsies performed in the same Endometrium anatomy and histology.

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.
