Primary retroperitoneal carcinosarcoma in a child: a case report

Abstract

Abstract Carcinosarcoma is a rare biphasic malignancy consisting of intermixed epithelial and mesenchymal elements. Carcinosarcoma is particularly rare among children. We accepted a 7 year old patient with retroperitoneal carcinosarcoma. The tumor was totally resected and no recurrence is found 11 months after operation. Literatures has been reviewed and there are few reports of primary retroperitoneal carcinosarcoma in children up to date. So we report the patient's clinical character, surgical resection, pathological and immunohistochemical analysis.
