ABSTRACT


Introduction: The reported incidence of abdominal wall endometriosis (AWE) ranges from 0.03% to 1.08%. A slightly more than 50 cases of abdominal wall endometriosis-associated adenocarcinoma have been reported; commonly clear cell carcinoma, followed by endometrioid adenocarcinoma and serous papillary carcinoma. All of these patients had a history of gynecological or obstetric surgery some time prior to the diagnosis of carcinoma.

Case Report: Here we report a case of a 39-year-old G0P0 female with no history of abdominal/pelvic surgery, who presented with isolated umbilicus endometriosis and an incidental finding of 2 mm adenocarcinoma associated with the endometriosis. Thorough systemic exam was non-eventful, other than a germline variant of the ATM gene of unknown significance.

Conclusion: Our case is unique as it is an isolated sporadic event of malignant transformation of endometriosis, without history of gynecological or obstetric surgery.

Keywords: Abdominal wall endometriosis, Clear cell carcinoma, Endometrioid adenocarcinoma, Malignant transformation of endometriosis
