Endometriosis continues to be a significant problem for women of childbearing age, with between 6 and 10 percent of women suffering from this condition. Despite its high prevalence, the diagnosis of endometriosis can be difficult due to its…

Endometriosis-associated fibrosis is a complex phenomenon, and the underlying mechanisms are still not fully understood. Fibrosis is invariably present in all forms of the disease and contributes to the classic endometriosis-associated symp…

Seromucinous tumors belong to a group of ovarian epithelial tumors. They were originally described as tumors characterized by Müllerian endocervical differentiation. Molecular genetic studies have indicated these tumors as endometriosis-ass…

This paper reveals the pathogenetic impact of the abnormal gut microbiota on the development of female reproductive system diseases. A dynamic imbalance between the altered microbiota and the macroorganism has many manifestations as hormona…

OBJECTIVE: To investigate the expression of proliferation and apoptotic factors (Ki-67, Bcl-2), inflammatory factors (NF-kβ p65, COX-2), adhesion factors (β-catenin), estrogen (ER-α) and progesterone receptors (PR-α) in ovarian endometrioma…

OBJECTIVE: To investigate the expression of moesin, p21-activated kinase 4 (PAK 4), matrix metalloproteinases (MMP 2, MMP 9), and CD34 in the eutopic and ectopic endometrium in different forms of adenomyosis. MATERIAL AND METHODS: Fifty ute…

OBJECTIVE: To study endometrial receptivity in infertile women with external genital endometriosis (EGE). SUBJECTS AND METHODS: Clinical, morphological, immunohistochemical, and molecular genetic examinations of endometrial aspiration pipel…

UNLABELLED: Endometriosis (EM) is morphologically characterized by the development of extrauterine endometrioid heterotopies, the major clinical symptoms of which is chronic pelvic pain, which is a serious problem not only in modern gynecol…

OBJECTION: To study the origin and morphological substrate of pain syndrome in deep infiltrating endometriosis involving the bowel. SUBJECTS AND METHODS: The investigation was conducted using the intraoperative material (resected portions o…

Adenomyosis, ovarian endometriosis and extragenital endometriosis are clinico-pathologic types of one nosologic form as endometrioid disease (ED). ED's clinical presentations are various, but they are essentially characterized by a pain syn…

The molecular biological features of the eutopic and ectopic endometrium were studied in 46 patients with adenomyosis, 44 with endometrioid cysts in the ovaries, and 34 with disseminated mixed forms of genital endometriosis. Reproductive-ag…

The purpose of the investigation was to study the morphological variants and molecular changes of the endothelial component of adenomyosis (AM) concurrent with endometrial adenocarcinoma (EAC). Monoclonal and polyclonal antibodies to ApoCas…

The purpose of the study was to reveal clinical and morphological parallels and to define molecular mechanisms, the regulation of proliferation, apoptosis, neoangiogenesis, and the extent of abnormal tissue in adenomyosis (AM). The surgical…

An immunoperoxidase test was used to reveal the expression of cytochrome P-450 aromatase in the eutopic and ectopic endometrium of 14 patients with ovarian endometriosis and 26 with adenomyosis, whose age ranged from 21 to 47 years (38+/-2.…

A complex morphological and morphometric study was used to examine endometrial biopsy specimens from 133 patients with bacterial vaginosis (BV). Chronic endometritis (CE) was detected in 100% of them. The morphological components of CE in B…

The expression of E-cadherin and beta-catenin in the eutopic and ectopic endometrium was studied in 40 patients with adenomyosis and 12 without this condition, by using an immunohistochemical test and enzyme immunoassay. There was increased…

The review of literature concerns some aspects of the pathogenesis of adenomyosis in terms of occurring molecular biological processes. It pools the literature data on endometrial capacity to be plunged into the deep myometrial layers--the …

Glandular cystic ovarian endometriosis (OE) is characterized by a more intensive blood supply than cystic OE. This type of OE is characterized by a high proliferative glandular epithelial activity detected by an immunohistochemical study us…

15 uteri removed surgically because of abruptio placentae (AP) were studied morphologically. AP develops as a process due to a combination of maternal (endometritis, gestosis, adenomyosis), placental (pathology of microvilli, hypercoagulati…

Adenomyosis cancerous transformation (AMCT) was observed in a 48-year old female without cancer of the endometrium. Various forms of transformation (stages of AMCT morphogensis) in and outside of denomyosis (AM) foci are described (adenomat…

A morphological analysis of 50 cases of adenomyosis (AM) and 150 cases of AM combination with leiomyoma (LM) with regard to their morphofunctional and histotopographical interrelations was performed. The asynchronous character and mosaicism…

75 cases of simple, cellular and mitotically active leiomyoma (LM) were studied immunohistochemically with the use of monoclonal antibodies against bcl-2 ("DAKO", 1:80), bax ("Calbiochem, 1:80), c-myc ("Novocastra", 1:100), CD 95 ("Dianova,…

A case of sygmoid endometriosis is described in a 40-year-old female. After clinical and endoscopic examination, the patient was operated for sigmoid tumor, acute obturation colon obstruction. Histologically diagnosis of intestinal wall end…

Clinicomorphological diagnosis of uterine endometriosis based on distinguishing forms of the disease different by their activity is considered. Quantitative morphological methods used for the first time allowed to define reliable mathematic…

Study of 52 patients with ovarian endometriosis supports the point of view about the relative autonomy of ovarian endometriosis from the cyclic hormonal alterations in female organism. In the foci of endometriosis the signs of differentiati…
