Endometrial Pathology

Abnormal uterine bleeding (AUB) is one of the most common indications for hysteroscopy. Most of the AUB cases occur due to endometrial or myometrium pathology. Among it, endometrial polyps (EP) and chronic endometritis (CE) prevalent in reproductive age, while endometrial hyperplasia (EH) and EP dominate in perimenopause. It was determined that EP and CE are characterized with menorrhagia and metrorrhagia approximately equally, whereas EH reveals AUB with oligomenorrhoea. Verification of exact endometrial pathology by ultrasound examination is hindered, that results in deviations of ultrasound and histological diagnosis. The usage of ultrasound data and AUB’s characteristics may improve the diagnostic accuracy on preadmission period.

Abstract Background Hysteroscopy is a commonly used technique for diagnosing endometrial lesions. It is essential to develop an objective model to aid clinicians in lesion diagnosis, as each type of lesion has a distinct treatment, and judgments of hysteroscopists are relatively subjective. This study constructs a convolutional neural network model that can automatically classify endometrial lesions using hysteroscopic images as input. Methods All histopathologically confirmed endometrial lesion images were obtained from the Shengjing Hospital of China Medical University, including endometrial hyperplasia without atypia, atypical hyperplasia, endometrial cancer, endometrial polyps, and submucous myomas. The study included 1851 images from 454 patients. After the images were preprocessed (histogram equalization, addition of noise, rotations, and flips), a training set of 6478 images was input into a tuned VGGNet-16 model; 250 images were used as the test set to evaluate the model’s performance. Thereafter, we compared the model’s results with the diagnosis of gynecologists. Results The overall accuracy of the VGGNet-16 model in classifying endometrial lesions is 80.8%. Its sensitivity to endometrial hyperplasia without atypia, atypical hyperplasia, endometrial cancer, endometrial polyp, and submucous myoma is 84.0%, 68.0%, 78.0%, 94.0%, and 80.0%, respectively; for these diagnoses, the model’s specificity is 92.5%, 95.5%, 96.5%, 95.0%, and 96.5%, respectively. When classifying lesions as benign or as premalignant/malignant, the VGGNet-16 model’s accuracy, sensitivity, and specificity are 90.8%, 83.0%, and 96.0%, respectively. The diagnostic performance of the VGGNet-16 model is slightly better than that of the three gynecologists in both classification tasks. With the aid of the model, the overall accuracy of the diagnosis of endometrial lesions by gynecologists can be improved. Conclusions The VGGNet-16 model performs well in classifying endometrial lesions from hysteroscopic images and can provide objective diagnostic evidence for hysteroscopists.

Histologic examination was performed on uterine biopsy samples of irregular cystic masses noted during caesarean section of a 2-year-old female Boer goat. Histopathologic examination revealed multifocal erosions of the superficial epithelium and multifocal infiltration of the endometrium by widely scattered viable and degenerate neutrophils, lymphocytes, and plasma cells admixed with mild amounts of cellular debris and hemorrhage. The endometrium was markedly expanded by many irregular cystic and hyperplastic glands. This is the first case report of endometritis and cystic endometrial hyperplasia in a goat in North America.

Background: Hysteroscopy an endoscopic procedure for visualization of uterine cavity may be extensively used in both primary and secondary infertility and abnormal uterine bleeding for evaluating intrauterine pathology. The objectives of this study were to visualize and identity intrauterine pathology in both primary and secondary infertility and abnormal uterine bleeding (AUB) by hysteroscopic evaluation and to perform hysteroscopic guided therapeutic procedures like endometrial currettage, polypectomy, adhesiolysis.Methods: Hysteroscopic evaluation of uterine cavity for any intrauterine pathology in AUB and Infertility. Adhesiolysis, polypectomy, endometrial biopsy misplaced copper T removal were carried out under hysteroscopic vision.Results: Intrauterine synechia in 20.51%, Submucous fibroid in 5.13%, bicornuate uterus, endometrial hyperplasia and endometrial polyp were seen in 2.56% patient each were detected in infertility group while 81.95% cases with AUB had abnormal intrauterine pathology commonest being endometrial hyperplasia in 33.33% followed by endometrial polyps in 23.81% cases, submucous fibroid and misplaced copper T in 9.52% each and intrauterine synechia in 4.76% patient. Endometrial biopsy and polypectomy was done in 23.80% each with AUB, misplaced copper T removal in 9.52% and adhesiolysis in 4.76% patient with AUB.Conclusions: Hysteroscopy remains gold standard for evaluating intrauterine lesions in abnormal uterine bleeding and infertility. A safe, simple minimally invasive procedure not only diagnostic but therapeutic modality for adhesiolysis, endometrial biopsy/curettage, polypectomy, misplaced copper T removal under direct vision with minimal complication within reach of every Gynaecologist thereby reducing burden of major surgical intervention.

Abstract Context.—Several endometrial diseases, such as endometrial hyperplasia, endometrial carcinoma, and endometrial polyps, have been reported to be associated with tamoxifen administration. We recently observed a high incidence of distinctive small blue cells in Papanicolaou tests of women who had received tamoxifen treatment for breast carcinoma. Objectives.—To define the characteristics of these small blue cells, to identify the patient population in which they are found, and to determine the clinical significance and possible etiology of these findings. Design.—A total of 154 Papanicolaou tests from 60 patients with a clinical history of tamoxifen therapy were reviewed retrospectively. Results.—Small blue cells were found in 40% of Papanicolaou tests from patients who received tamoxifen therapy. Patients with small blue cells in their Papanicolaou tests were an average of 9 years older at the time tamoxifen therapy was initiated than those without. Among the available follow-up surgical biopsies, no malignant diagnoses were made. Conclusions.—We conclude that these distinctive small blue cells are found more frequently in older patients and most probably represent proliferative reserve cells of cervical/vaginal epithelium resulting from the estrogenic agonist effect of tamoxifen. More importantly, they are nonneoplastic in nature.
