Primary peritoneal clear cell carcinoma arising in the setting of abdominal wall Endometriosis: A case report and review of the literature

• Primary peritoneal clear cell carcinoma can arise from endometriotic implants within the abdomen and pelvis. • Immunohistochemistry can be used to confirm primary disease site. Endometriotic origin can be inferred based on clinical history and intraoperative findings suggestive of endometriosis. • While no standardized treatment exists, consideration should be given to cytoreductive surgery with adjuvant chemotherapy. Adjuvant radiation can also be considered for local control.
