This retrospective study analyzed the clinicopathological features of 17 ovarian carcinoma cases associated with endometriosis, identifying clear cell carcinomas and endometrioid adenocarcinomas as the predominant histological subtypes. The researchers observed that these tumors often presented at earlier stages compared to common epithelial ovarian cancers, with typical endometriosis or iron-laden macrophage infiltration evident in over half of the cases. The authors emphasize that cytoreductive surgical treatment is critical for planning appropriate post-operative management strategies for these specific malignancies. This paper is centrally about endometriosis — specifically its role as a precursor lesion for clear cell and endometrioid ovarian carcinomas.

Abstract

IntroductionSubstantial histopathology data provide evidence that endometriosis might be viewed as a precursor lesion of endometrioid and clear cell carcinoma of the ovary, via intermediary atypical borderline lesions. Also, genes involved in both endometriosis and epithelial ovarian cancer have been shown to play a role in the pathogenesis of endometriosis-associated ovarian carcinoma.Material and methodsA retrospective study of 17 cases of ovarian carcinomas associated with endometriosis, diagnosed between 2000 and 2009, at Aretaieion Hospital of University of Athens, is presented. 10/17 cases in this study (58.8%) were clear cell carcinomas (CCC), 6/17 cases (35.3%) were endometrioid adenocarcinomas (EAC) and 1/17 cases (5.9%) was a serous carcinoma associated with ovarian endometriosis. Patients's age was 27-76 years (mean age 58 years). Typical ovarian endometriosis was documented in 8/17 (47%) of the tumors. In 9/17 cases, areas of fibrosis or cystic lesions infiltrated by iron-laden macrophages and endometrial-like stroma, consistent with endometriosis, were observed.ConclusionIn comparison with common epithelial ovarian cancers, CCC and EACs of the ovary were presented at earlier stages. Cytoreductive surgical treatment is critical in order to plan appropriate post-operative management.

Abstract

Introduction Substantial histopathology data provide evidence that endometriosis might be viewed as a precursor lesion of endometrioid and clear cell carcinoma of the ovary, via intermediary atypical borderline lesions. Also, genes involved in both endometriosis and epithelial ovarian cancer have been shown to play a role in the pathogenesis of endometriosis-associated ovarian carcinoma.

Material and methods

A retrospective study of 17 cases of ovarian carcinomas associated with endometriosis, diagnosed between 2000 and 2009, at Aretaieion Hospital of University of Athens, is presented. 10/17 cases in this study (58.8%) were clear cell carcinomas (CCC), 6/17 cases (35.3%) were endometrioid adenocarcinomas (EAC) and 1/17 cases (5.9%) was a serous carcinoma associated with ovarian endometriosis. Patients’s age was 27–76 years (mean age 58 years). Typical ovarian endometriosis was documented in 8/17 (47%) of the tumors. In 9/17 cases, areas of fibrosis or cystic lesions infiltrated by iron-laden macrophages and endometrial-like stroma, consistent with endometriosis, were observed.

Conclusion

In comparison with common epithelial ovarian cancers, CCC and EACs of the ovary were presented at earlier stages. Cytoreductive surgical treatment is critical in order to plan appropriate post-operative management. Similar content being viewed by others
