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.

Abstract

BACKGROUND: Endometriosis occurring in a surgical scar is well recognized and occurs mainly in patients with a history of hysterectomy or Caesarean section. Scar endometriosis, as well as endometriosis at other sites, can undergo malignant change. Endometrioid carcinoma is the most common malignant tumour arising in endometriosis. However, clear cell carcinoma can also occur but is unusual. AIM: To discuss the diagnosis and management of such a case. METHODS: We report a case of primary clear cell carcinoma in endometriosis of a Caesarean section scar and review the literature. RESULTS: The patient presented with a large right lower quadrant abdominal wall mass within a Caesarean section scar. Histological examination revealed a clear cell carcinoma. The patient had a prior history of pelvic endometriosis. According to the Irish National Cancer Registry, this is the first reported case of a primary abdominal wall clear cell carcinoma developing within a Caesarean section scar in Ireland. CONCLUSION: Any lesion occurring in a Caesarean section scar with a history of previous endometriosis cannot be underestimated and warrants careful clinical follow-up and histological evaluation as appropriate.

Abstract

Background Endometriosis occurring in a surgical scar is well recognized and occurs mainly in patients with a history of hysterectomy or Caesarean section. Scar endometriosis, as well as endometriosis at other sites, can undergo malignant change. Endometrioid carcinoma is the most common malignant tumour arising in endometriosis. However, clear cell carcinoma can also occur but is unusual. Aim To discuss the diagnosis and management of such a case.

Methods

We report a case of primary clear cell carcinoma in endometriosis of a Caesarean section scar and review the literature.

Results

The patient presented with a large right lower quadrant abdominal wall mass within a Caesarean section scar. Histological examination revealed a clear cell carcinoma. The patient had a prior history of pelvic endometriosis. According to the Irish National Cancer Registry, this is the first reported case of a primary abdominal wall clear cell carcinoma developing within a Caesarean section scar in Ireland.

Conclusion

Any lesion occurring in a Caesarean section scar with a history of previous endometriosis cannot be underestimated and warrants careful clinical follow-up and histological evaluation as appropriate. Similar content being viewed by others
