[Clear cell adenocarcinoma from cicatricial endometriosis]

Clear cell adenocarcinoma arising from abdominal wall endometriosis (AWE) is extremely rare. 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.
