RESUMO
UNLABELLED: Surface epithelial tumors are the most important group of neoplasm of the ovary. These tumors are classified according to the following parameters: cell type, pattern of growth, amount of fibrous stroma, atypia and invasiveness. AIM: This study aimed to identify ovarian tumours, especially borderline type, by applying last parameters of criteria for histologic diagnostic of ovarian neoplasms. MATERIAL AND METHODS: The retrospective study included 116 patients with ovarian tumors diagnosed, investigated, surgically treated at the Obstetrical and Gynecological Hospital Botosani in the past 9 years (2002-2010). In this interval were recorded 116 cases of epithelial ovarian tumors. In sample processing, we used formalin for fixation, paraffin for specimen embedding and hematoxilin-eosin for staining. The age of the patients ranged between 19-86 years. RESULTS: From 116 cases, 57 (49,1%) were benign, 40 (34,5%) malignant and 19 (16,4%) borderline. In our study of benign neoplasms, we included 37 cases of serous tumours (64,9%) and 20 cases of mucinous types (35%). In the group of borderline tumours, the serous type was the most frequent (13 cases), followed by mucinous types (6), including 5 cases of intestinal type and 1 of endocervical pattern. The malignant tumors, according with decreasing order of frequency, were the following: 19 serous (47,5%), 8 mucinous (20%), 11 endometroid type (27,5%) and one of each cases of clear cell and small cell tumors (2,5%). CONCLUSIONS: Of great interest in our research was to identify ovarian borderline tumours, still representing a controversial group, in the same time corresponding with a scientiphic progress. Because the spectrum of epithelial tumors is very large, extensive sampling is essential to carry out all these important determinations, because benign, borderline and malignant patterns can be found in the same tumor.
