We report a case of a 60-year-old woman with a history of cesarean section and surgically treated AWE. Decades after initial resection, she developed recurrent pain and a palpable mass. Initial evaluation raised suspicion for other conditions, leading to a diagnostic delay. Subsequent workup confirmed clear cell adenocarcinoma. She underwent radical surgery and was diagnosed with FIGO stage IV B disease. The case highlights the malignant potential of endometriosis and the need for clinical vigilance.<\/jats:p>","DOI":"10.61409\/v10250794","type":"journal-article","created":{"date-parts":[[2026,4,9]],"date-time":"2026-04-09T10:39:09Z","timestamp":1775731149000},"page":"1-3","source":"Crossref","is-referenced-by-count":0,"title":["Clear cell adenocarcinoma from cicatricial endometriosis"],"prefix":"10.61409","author":[{"given":"Josefine Reinhardt","family":"Nielsen","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Catrine","family":"Carlstein","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jacob Brink","family":"Laursen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marie","family":"Boennelycke","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ebbe","family":"Thinggaard","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"40208","published-online":{"date-parts":[[2026,4,6]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"Andolf E, Thorsell M, K\u00e4ll\u00e9n K.
