title: Endometrioid carcinoma arising in endometriosis. Case report.
abstract: Malignant transformation arising in endometriosis has been reported in some cases. Following Sampson's criteria, about 0.7%-1% of all cases of endometriosis undergo malignant transformation and the ovary is the most frequent site. A case is reported of a patient with endometriosis which, after 10 years, grew into ovarian endometrioid carcinoma. The relationship between endometriosis and cancer suggests a radical treatment of endometriosis and a careful assessment of postmenopausal woman presenting reactivation signs.
