In this case report we present the case of a 50-year-old woman with clear cell carcinoma arising from an endometriotic nodule of the rectovaginal septum and discuss about the clinic, difficulty for diagnosis, evolution and treatment of the disease. The published data on this strange location of clear cell carcinoma, its etiopathogenesis and the risk factors for the malignancy of an endometriotic nodule are analysed. We conclude despite its low incidence, the malignancy of RVS nodule of extra-ovarian endometriosis is possible and should be considered when a cystic or solid-cystic lesion appears in the pelvis in a woman with a long history of endometriosis.</Abstract> <AbstractLanguage>English</AbstractLanguage> <Keywords>Endometriosis,Rectovaginal Septum,Malignancy,Clear Cell Carcinoma</Keywords> <URLs> <Abstract>https://jmedicalcasereports.org/ubijournal-v1copy/journals/abstract.php?article_id=9309&title=Clear Cell Carcinoma on an Endometriotic Nodule of The Recto-Vaginal Septum: Case Report</Abstract> </URLs> <References> <ReferencesarticleTitle>References</ReferencesarticleTitle> <ReferencesfirstPage>16</ReferencesfirstPage> <ReferenceslastPage>19</ReferenceslastPage> <References>Benoit L, Arnould L, Cheynel N, Diane B, Causeret S, Machado A, Collin F, Fraisse J, Cuisenier J.
