Incidenţa endometriozei şi a endometriozei atipice în cazul tumorilor ovariene epiteliale

Introduction. Several previous studies have identified an association between endometriosis and the development of ovarian carcinomas. This study aims to follow-up the prevalence of endometriosis and the histological features in ovarian tumors. Materials and method. The study group included 50 patients from the County Emergency Hospital of Galaţi diagnosed with different histological types of ovarian tumors of the surface epithelium during the period 2015-2018. The cases were reviewed in order to highlight the presence of endometriosis and the different histopathological changes. Results. In this study, the incidence of endometriosis was 14% (7/50). The average age of patients in the group with endometriosis associated with ovarian tumors was 59.4±11.35, respectively 59.5±13.4 in the group presenting only ovarian tumors. From the group of 50 patients, 29 (58%) were diagnosed with serous carcinoma, 8 (16%) with endometrioid carcinoma, 5 (10%) with mucinous carcinoma, 4 (8%) with serous borderline tumors, one (2%) with mucinous borderline tumor, one (2%) with clear cell carcinoma, one (2%) with undifferentiated carcinoma, and one (2%) with malignant Brenner tumor. From the seven cases of tumors associated with endometriosis, two presented areas with atypia, considered premalignant lesions. Conclusions. Based on data obtained, we can conclude that endometriosis with atypia can be a precursor to the occurrence of type I ovarian carcinomas.
