A large suspicious tumour of the Douglas space, with contact to the uterus and the rectal wall was described. The rest of the exploration was normal, specially the rest of the peritoneum. Histopathology revealed a malignant transformation of a superficial peritoneal endometriosis. Secondary surgery was thus completed by laparoscopy with bilateral pelvic and para-aortic lymph node dissections, omentectomy and multiple peritoneal biopsies. All staging samples were free of cancer; therefore no complementary therapy was administered. After 18\u2005months of follow-up, consisting of clinical examination and pelvis magnetic resonance imaging every 6\u2005months, we did not observe any recurrence. Malignant transformation of superficial peritoneal endometriosis is a rare disease and surgical management seems to be the main treatment.<\/jats:p>","DOI":"10.1136\/bcr-2012-007730","type":"journal-article","created":{"date-parts":[[2013,8,26]],"date-time":"2013-08-26T05:53:31Z","timestamp":1377496411000},"page":"bcr2012007730","source":"Crossref","is-referenced-by-count":10,"title":["Malignant transformation of superficial peritoneal endometriosis lesion"],"prefix":"10.1136","volume":"2013","author":[{"given":"Eva","family":"Marchand","sequence":"first","affiliation":[{"name":"Department of Gynecology, Lariboisiere Hospital, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Delphine","family":"Hequet","sequence":"additional","affiliation":[{"name":"Department of Gynecology, Lariboisiere Hospital, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anne","family":"Thoury","sequence":"additional","affiliation":[{"name":"Department of Gynecology, Lariboisiere Hospital, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Emmanuel","family":"Barranger","sequence":"additional","affiliation":[{"name":"Department of Gynecology, Lariboisiere Hospital, Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2013,8,26]]},"reference":[{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1001\/archsurg.1925.01120100007001","article-title":"Endometrial carcinoma of the ovary, arising in endometrial tissue in that organ","volume":"2013","author":"Sampson","year":"1925","journal-title":"Arch Surg"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.2","doi-asserted-by":"crossref","first-page":"1559","DOI":"10.1016\/j.fertnstert.2008.08.007","article-title":"The relationship of endometriosis and ovarian malignancy: a review","volume":"2013","author":"Nezhat","year":"2008","journal-title":"Fertil Steril"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.3","doi-asserted-by":"crossref","first-page":"385","DOI":"10.1016\/S1470-2045(11)70404-1","article-title":"Association between endometriosis and risk of histological subtypes of ovarian cancer: a pooled analysis of case-control studies","volume":"2013","author":"Pearce","year":"2012","journal-title":"Lancet Oncol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.4","doi-asserted-by":"crossref","first-page":"164","DOI":"10.1016\/j.ygyno.2011.10.001","article-title":"The association between endometriosis and ovarian cancer: a review of histological, genetic and molecular alterations","volume":"2013","author":"Munksgaard","year":"2012","journal-title":"Gynecol Oncol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.5","doi-asserted-by":"crossref","first-page":"951","DOI":"10.1097\/00003081-198023030-00024","article-title":"Malignant tumors arising in endometriosis","volume":"2013","author":"Mostoufizadeh","year":"1980","journal-title":"Clin Obstet Gynecol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.6","doi-asserted-by":"crossref","first-page":"133","DOI":"10.1097\/00004347-200104000-00004","article-title":"Malignancy in endometriosis: frequency and comparison of ovarian and extraovarian types","volume":"2013","author":"Stern","year":"2001","journal-title":"Int J Gynecol Pathol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.7","doi-asserted-by":"crossref","first-page":"123","DOI":"10.1016\/0090-8258(88)90055-8","article-title":"Malignant extraovarian endometriosis: two case reports and review of the literature","volume":"2013","author":"Brunson","year":"1988","journal-title":"Gynecol Oncol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.8","first-page":"1023","article-title":"Malignant neoplasms arising in endometriosis","volume":"2013","author":"Heaps","year":"1990","journal-title":"Obstet Gynecol"},{"key":"2025082805100366000_2013.aug26_1.bcr2012007730.9","doi-asserted-by":"crossref","first-page":"51","DOI":"10.1016\/j.gyobfe.2007.06.019","article-title":"Postmenopausal malignant transformation of extragenital endometriosis.
