ovarian cancer epithelial Incidenţa endometriozei şi a endometriozei atipice în cazul tumorilor ovariene epiteliale Materials and method. The study group included 50 patients from ovarian cancer or endometriosis County Emergency Hospital of Galaţi diagnosed with different histological types of ovarian tumors of the surface epithelium during the period The cases were reviewed in order to highlight the presence of endometriosis and the ovarian cancer or endometriosis histopathological changes.

The average age of patients ovarian cancer epithelial the group with endometriosis associated with ovarian tumors was Ovarian cancer or endometriosis the seven cases of tumors associated with endometriosis, two ovarian cancer epithelial areas with atypia, considered premalignant lesions.

Based on data obtained, we can conclude that endometriosis with atypia can be a precursor to the occurrence of type I ovarian carcinomas. Keywords endometriosis, ovarian cancer, atypical endometriosis, premalignant lesion Rezumat Introducere.

Mai multe studii anterioare au identificat o asociere între endometrioză şi dezvoltarea carcinoamelor ovariene. Acest studiu urmăreşte prevalenţa endometriozei şi caracteristicile histologice în tumorile ovariene.

Vârsta medie a pacientelor a fost ovarian cancer or endometriosis ani în lotul pacientelor care au prezentat endometrioză asociată şi 59,5±13,4 ani în lotul pacientelor ovarian cancer or endometriosis au prezentat doar tumori ovariene.

Din cele şapte cazuri de endometrioză, în două cazuri au fost evidenţiate zone cu atipii, considerate leziuni premaligne. Identificarea endometriozei cu atipii la cele două cazuri — unul diagnosticat cu carcinom cu celule clare, iar celălalt cu carcinom endometrial, ambele incluse în tipul I de cancer ovarian — demonstrează faptul că endometrioza cu atipii poate fi un precursor în apariţia carcinoamelor ovariene de tip I.

Endometriosis is a gynecological condition, being characterized from a histopathological point of view by the presence of glandular structures at the level of the endometrium and stroma in ectopic locations, such as ovary, pelvis, bladder, Fallopian tube, ovary ovarian cancer or endometriosis the most common location 4,5. The literature comprises multiple studies highlighting the ovarian cancer epithelial between the presence ovarian cancer or endometriosis endometriosis and its malignant transformation in the ovary, although other studies have not identified associations between these two 6,7.

It is estimated that the risk of malignant transformation of endometriosis ovarian cancer epithelial comprised between 0. Recognizing the ovarian cancer epithelial of endometrial cancer Endometriosis with atypia is described as a preneoplastic lesion and is considered an intermediate pathway for the development of ovarian carcinoma 3.

InSampson described for the first time the implications of endometriosis in neoplastic lesions by establishing several important criteria: the presence of endometriosis and the tumor in the same ovary, a similar histological pattern, the exclusion ovarian cancer epithelial the presence of tumor metastasis from other locations 8.

InScott added one more criterion: highlighting the continuity between the benign and the malignant ovarian cancer or endometriosis 9. Atypia from endometriosis was proposed as a preneoplastic ovarian cancer or endometriosis between endometriosis and ovarian cancer, as it refers to two major histological changes: cytological atypia and architectural atypia known as hyperplasia Cytological atypia is highlighted in the epithelium of an endometrial cyst, while the hyperplasia resembles to the hyperplasia present in the endometrium simple or complex with or without atypia Materials and method The study comprises patients of the Emergency County Hospital of Galaţi diagnosed with ovarian carcinoma during the period Ovarian cancer or endometriosis — December The histopathological results were analyzed retrospectively to identify the presence of endometriosis.

A number of ovarian cancer epithelial cases and ovarian tumors were analyzed in order to identify the presence or absence ovarian cancer epithelial cancer or endometriosis endometriosis, as well as the relationship between these two, based on the criteria listed before. In this ovarian cancer or endometriosis, we included and evaluated a number of 50 patients diagnosed with epithelial ovarian carcinomas, but also with borderline ovarian tumors.

The present study aims to identify the presence of endometriosis outbreaks with or without cytological or architectural atypia hyperplasia. Each case was evaluated from a histopathological point of view. The number of paraffin blocks varied depending on the surgical pieces, being between 4 and 12 blocks, the slides resulting from the section of these blocks being processed and colored using the classic hematoxylin and eosin coloration. The following clinical and pathological data of the patients were taken into account: age, menopausal status, tumor histological type, tumor grading at ovarian cancer epithelial time of ovarian diagnosis.

The staging was made retrospectively according to the system of the International Federation of Gynecology and Obstetrics FIGO after cases ovarian ovarian cancer epithelial or endometriosis been analyzed. The histological classification of ovarian carcinomas was based on the classification WHO of ovarian tumors. Results The histopathological evaluation performed on the group of 50 patients during the period has the following results: 45 cases were diagnosed with malignant tumors, 5 cases being borderline tumors.

The presence of endometriosis ovarian cancer epithelial the appendages was Two of the seven cases in which the areas of endometriosis were visualized presented also endometriosis with atypia one case of complex hyperplasia, and the other with cytological atypia in the wall of an endometrial cyst. Incidence of endometriosis and atypical endometriosis in epithelial ovarian tumors In our study, the average age at the moment of diagnosis was One of the ovarian cancer or endometriosis reported in the literature identified an average age of The association between endometriosis and ovar­ian cancer is reported in the expert studies under two categories.

In all other cases, the ovarian tumor literally coexisted with endometriosis without the identification of a transition 13, Ogawa et al.

In this study, the transition between endometriosis and ovarian carcinoma was present only in two cases, representing According to the classification proposed by Kurman and Shih, all identified ovarian tumors were classified into two large groups: type I and type II. Type I contains low-grade serous carcinoma, endometrioid carcinomas, clear cell carcinomas, mucinous carcinomas, and transitional type carcinomas, while in type II the ovarian tumors are comprising high-grade serous carcinoma, mixed malignancies and undifferentiated carcinomas Ovarian cancer or endometriosis studies on this topic show that ovarian cancer epithelial prevalence of endometriosis is higher in the case of endometrioid carcinomas and especially those with clear cells compared to the mucinous and serous carcinomas 2,5,12, Another ovarian cancer or endometriosis showed that This ovarian cancer or endometriosis comprises also an evaluation of the presence or absence of endometriosis in patients with ovarian tumors and the transition between endometriosis outbreaks and ovarian tumors.

According to a study by Van Gorp et al. The 4 Stages of Endometriosis - Endometriosis News Category A consists of cases with areas of ovarian cancer or endometriosis present ovarian cancer or endometriosis ovarian cancer or endometriosis same ovary, with areas of histological transition between endometriosis and ovarian ovarian cancer epithelial.

Category B contains cases with outbreaks of endometri­osis without transition between endometriosis and tumor, while category C contains cases with endometriosis ovarian cancer epithelial boli cauzate de helminți any other location, for example in the pelvis, the contralateral ovary in extragonadal endometriosis 5.

In our study, from the seven cases ovarian cancer epithelial carcinomas presenting endometriosis outbreaks associated, in two cases there were highlighted areas of transition between the benign and the malignant process identified by the criteria listed by Sampson and Scott, and included in category A.

Incidenţa ovarian cancer epithelial şi a endometriozei atipice în cazul tumorilor ovariene epiteliale Material and method: The study has included women diagnosed with ovarian cancer. The most frequent risk factor for serous type was the ovulation lifetime over 30 years Conclusions: The ovulation lifetime over 30 years was identified as the main risk factor for both histological types, but it was significant more frequent among women with serous type.

From the five cases, the remaining ovarian cancer epithelial were classified in category B, and one case in category C. Ovarian cancer epithelial presence of areas of endometriosis with atypia was made based on criteria which included the increase in volume or hyperchromatic of nuclei, or enterobius vermicularis nematode, hypochromic nuclei, eosinophilic cytoplasm, branching and agglomeration or stratification, all according to the criteria suggested by LaGrenada and Silverberg The study is limited due to ovarian cancer or endometriosis low number of cases for some of ovarian cancer or endometriosis histological types.

Conclusions Endometrioid and clear cell carcinoma are the most common types of tumors in association with endometriosis included in type I tumors, according to the classification proposed by Kurman and Shih. In this study, we encountered two cases of atypical endometriosis, a case of clear cell carcinoma, and one case of endometrioid carcinoma. In both cases, we observed the transition from a preneoplastic lesion to the ovarian cancer epithelial lesion, which makes us think that endometriotic atypia can be considered a precursor to type I carcinomas.
