According to modern views based on evidence-based medicine, the concept of "poly-endometrium" is defined as a benign, exophytic nodophilic formation of the uterine mucus that consists of glands and stroma, predominantly fibrous, containing a "tangle" of thick-walled blood vessels. The aim of the study – to learn the morphological features of tissues of polyps of the body of the uterus and endometrium with the establishment of the role of inflammatory factor in the pathogenesis of hyperproliferative changes in women of reproductive age. Materials and Methods. The article presents the results of a survey of 62 patients of reproductive age with polyps in the body of the uterus. The presence of the glandular component in 79.03 % of cases, fibrotic polyps – 12.9 %, and micro-polyps – 8.06 % were determined, respectively. The combination of polyps with non-atypical endometrial hyperplasia was detected in 80 % of patients with micro-polyposis, in 63.6 % of women – with glandular-cystic polyps of the uterine body, in 44.4 % of the examined – with glandular-fibrous endometrial polyps and in 37.5 % of patients – with fibrous polyps. Immunohistochemically, CD138 expression was detected both in the tissues of the polyps of the uterus and adjacent endometrial tissues in 43.5 % of cases, which became a marker of the chronic endometritis in the part of the surveyed, which formed the basis of the pathogenetic approaches in the treatment of such a pathology. For processing data standard procedures using Microsoft Excel were used. The research was conducted in the Laboratory of Pathomorphology of the Department of O. Lukyanova Institute of Pediatrics, Obstetrics and Gynecology of the National Academy of Medical Sciences of Ukraine, head of the department – Corresponding Member of the National Academy of Medical Sciences of Ukraine, Professor T. Zadorozhna. Results and Discussion. In clinical analysis of complaints of polyps of the body of the uterus, clinical manifestations in the form of menstrual cord disturbance were 13 (20.97 %) patients, in 11 (17.74 %) patients there were no complaints about the desired pregnancy, at the same time as 38 (61.29 %) women were asked to carry out a preventive examination, which does not contradict the results of other researchers. During the morphological study, we established the following features of the polyps of the body of the uterus in women of reproductive age: the most frequently tested polyps of the body of the uterus, which had the glandular component – in 49 (79.03 %) cases, of which the glandular-cystic structure was found in 22 (35.48 %) of patients, the glandular-fibrous structure was in 27 (43.55 %) patients, approximately the same values ​​were found in fibrous polyps of the body of the uterus – 8 (12.90 %) of women and micropolymers of endometrium – in 5 (8.06 %) cases respectively. We found that in all groups of patients with polyps in the body of the uterus, there were signs of non-atypical hyperplasia of the endometrium. It should be noted that, according to literature, endometrial polyps larger than 15 mm were associated with hyperplasia. The above data is an important indication that the unidirectional determination of the positive expression of the CD138 inflammatory marker, both in the tissue of the polyp of the uterus and in the endometrial tissue, indicates the unity of the inflammatory factor in the pathogenesis of hyperproliferative processes and proves the significant role of the inflammatory process in the development of its pathological conditions and justifies the necessity take into account this fact in approaches to the tactics of patient management. Conclusions. The results of the conducted morphological and immunohistochemical research indicate that the basis of the formation of polyps of the body of the uterus is the inflammatory process, which is confirmed morphologically with the presence of chronic endometritis and a positive reaction to CD138. The study of pathogenetic mechanisms for the formation of endometrial pathology is a key factor in the development of methods for correction of these pathological processes, which thus allows to increase the efficiency of treatment and preserve reproductive health.

The peculiarities of benign proliferative pathology of endometrium including their combination in women of reproductive age are reviewed in the article. Materials and methods. The results of pathohistological research of benign proliferative pathology of endometrium (without atypia) were analyzed. Statistical data processing was performed by means of MedStat software package. Results. The obtained results revealed that benign proliferative pathology of endometrium is one of the most frequent gynaecological malignancies among female patients of reproductive age accounting for 52.2 % cases. Endometrial polyps were found to be accompanied by morphological peculiarities indicating chronic inflammatory process in endometrium in 56.5% cases (p<0.05) in comparison with endometrial hyperplasia in 38.2% cases, proving the presence of long-term inflammation in endometrial tissue and its trigger role in the development of the proliferative processes. Among patients with chronic salpingo-oophoritis, infertility was revealed in almost half of cases (44.5% of patients with endometrial polyps, 40.5% of patients with endometrial hyperplasia and 48.3% of women with combined proliferative pathology of endometrium) clinically confirming the data of morphological research. Peculiar signs of proliferative processes in genitals were determined, namely coexistence of uterine and endometrial pathology: endometrial hyperplasia was found in 40.4% of patients with uterine leiomyoma and 30.3% of patients with adenomyosis. The same combinations were peculiar for patients with endometrial polyps: endometrial hyperplasia was found in 30.1% of patients with uterine leiomyoma and 36.3% of patients with adenomyosis. Menstrual disorders were revealed in every third woman with endometrial hyperplasia (30.3%) and co-existent polyposis (30.2%). Keywords Problem statement and analysis of the recent researchOver the past decades there has been a significant increase in the incidence of endometrial hyperplasia, cancer, and malignant endometrial hyperplastic processes (EHP) [9]. The EHP group is represented by an aggregate of morphological and biological heterogenic changes in endometrium varying from excessive proliferation to endometrial cancer [11]. This group of diseases includes different variants of hyperplasia and endometrial polyps.Endometrial hyperplasia is a benign pathology of uterine lining characterized by advanced clinicopathologic manifestations from simple to complex hyperplasia to atypical precursor of endometrial cancer, which develops on the background of absolute or relative hyperestrogenia [7]. Although estrogenic stimulation of endometrium is considered the main etiological risk factor for the development of endometrial hyperplasia, some researchers indicated other factors, such as immunosuppression and infection [13].Endometrial polyps are local benign proliferation of uterine lining along with subjacent stroma [8].A number of pathologists demonstrated that endometrial polyps develop initially in focal basal hyperplasia o...
