Rupture of aneurysm occurs from the primary intimal disruption, which spreads into thinned out media and adventitia. Rupture is caused by unstable atherom, hypocellularity, loss of contractile characteristics of smooth muscle cells in intima and media, neovascularization of the media, as well as by the activity of the macrophages in the lesion.

To establish the role of co-overexpression of bcl-2 and c-myc protooncogenes in uterine cervix carcinogenesis, we examined 138 tissue samples of low grade cervical squamous intraepithelial lesions (SIL), high grade SIL, portio vaginalis uteri (PVU) carcinoma in situ and PVU invasive carcinoma, stage IA-IIA (study group) and 36 samples without SIL or malignancy (control group). The expression of bcl-2 and c-myc was detected immunohistochemically using a monoclonal antibody. Fisher's exact test (P<0.05) was used to assess statistical significance. Overexpression of bcl-2 was found to increase in direct relation to the grade of the cervical lesions. High sensitivity was of great diagnostic significance for the detection of these types of changes in the uterine cervix. On the basis of high predictive values it can be said that in patients with bcl-2 overexpression there is a great possibility that they have premalignant or malignant changes in the uterine cervix. Co-overexpression of bcl-2 and c-myc oncogenes was found only in patients with PVU invasive carcinoma (6/26-23.0%). Statistically significant difference was not found in the frequency of co-overexpression in patients with PVU invasive carcinoma in relation to the control group (Fisher's test; P=0.064). The method's sensitivity of determining these oncogenes with the aim of detecting PVU invasive carcinoma was 23%, while specificity was 72.2%. On the basis of high predictive values (100%), speaking in statistical terms, it can be concluded that all patients with co-overexpression of bcl-2 and c-myc oncogenes will have PVU invasive carcinoma. We confirmed in our research that co-overexpression of bcl-2 and c-myc oncogenes was increased only in PVU invasive carcinoma. However, a more extensive series of samples and additional tests are required to establish the prognostic significance of bcl-2 and c-myc co-overexpression in cervical carcinogenesis.

Myomas develop as a result of increased mitotic (proliferating) activity of smooth muscle cells. In this study we examined the pathohistological samples of 176 myomas and their endometria that were obtained after hysterectomy from patients in the proliferative (follicular) and secretory (luteal) phase of the menstrual cycle. We examined the mitotic activity of the myoma cells in both phases and established that the average number of mitoses in the proliferative phase was significantly larger compared to the secretory phase, and that in the proliferative phase of the cycle there exists a statistically significant convergent association of the number of mitoses in the endometrium and in myomas. The number of endometrial mitoses is significantly larger than in myomas in both phases of the cycle

AbstractOmphalocele is the most common congenital defect of the abdominal wall and in a large percentage of cases it is associated with chromosomal anomalies. In this case report during the regular ultrasound examination at 11 weeks of gestation, omphalocela, whose scope was 90% of fetal abdomen, was diagnosed. Karyotype analysis showed the presence of chromosomal aberrations 47 XX + 18 (Edwards syndrome). After the presentation of the severity of congenital anomalies and characteristic of the Edwards syndrome patient decided to terminate the pregnancy.

Background/Aim. Lymphomas are malignant diseases of lymphocytes. There are two basic types of lymphoma: Hodgkin's lymphoma (HL) whose main characteristic is the presence of Reed-Sternberg cells and non-Hodgkin's lymphoma (NHL), which presents a heterogeneous group of diseases, and depending on the growth rate and the course of the disease, they can be indolent (slow-growing) and aggressive (fast-growing). Follicular lymphoma (FL) is the most common indolent form of NHL, while diffuse large B-cell lymphoma (DLBCL) is the most common aggressive form. Case report. This paper presents a case of NHL, DLBCL, localized in the cervix, histo-pathologically diagnosed in a 35-year-old woman who, after a cervical biopsy, was patho-histologically diagnosed with mild dysplasia (CIN1 / L-SIL) of the cervical epithelium and, after that, an infection with Human Papilloma Virus (HPV), subtypes 16 and 31 was proven. The diagnosis of DLBCL was patho-histologically confirmed on a conical section of the vaginal portion of the uterus, after which the disease was treated with eight cycles of chemotherapy (HT) according to the RCHOP protocol. Conclusion. The coexistence of CIN1 / L-SIL and NHL is random and may overlook concomitant cervical lymphoma, which is usually localized subepithelially, if the biopsy is not adequately performed and if HPV serotyping is not performed.
