This case report describes a patient with a history of pelvic endometriosis who presented with a large right lower quadrant abdominal wall mass located within a Caesarean section scar, and histology showed primary clear cell carcinoma arising in scar endometriosis; the authors also review related literature. They note that, although scar endometriosis is recognized and malignant transformation can occur, clear cell carcinoma is unusual, and this report is described as the first reported primary abdominal wall clear cell carcinoma developing within a Caesarean section scar in Ireland per the Irish National Cancer Registry. A limitation explicitly acknowledged by the paper format is that it is a single-patient report supported by a narrative literature review rather than original case-control data. This paper is centrally about endometriosis — it documents malignant transformation of Caesarean section scar endometriosis into primary abdominal wall clear cell carcinoma.
