To date, about thirty cases have been reported in the literature. This article provides a case report and literature review of an infrequent occurrence with poor prognosis. Case Report: A 45-year-old woman with pelvic pain and an abdominal mass came to our attention. Her medical history was notable for two previous cesarean sections. Physical examination revealed a smooth, multilocular mass measuring about 20 cm, arising from the previous surgical scar. Histology revealed clear-cell carcinoma resulting from the transformation of abdominal wall endometriosis. Given the disease extent, the patient underwent front-line chemotherapy. After several and multiple chemotherapy regimens, there was a disease progression that resulted in the death of the patient in 7 months. The literature review showed that a previous cesarean section was present in 91% of cases. Besides, approximately 26.5% of women died within 12 months of being diagnosed. The mean age of women was 45.88 years, while the average size of the lesion was 11 cm. Conclusion: Clear cell carcinoma is a rare but occurring event. Middle-aged women showing an abdominal wall mass in close relation with a surgical scar from a previous cesarean section must be promptly investigated. Treatment options usually include surgery and chemotherapy with poor results.</style></abstract></record></records></xml>
