Abstract:

Extraskeletal Ewing sarcoma in pregnancy is very rare in clinic, with a high rate of recurrence and metastasis, and there is no unified and effective treatment plan at present. This paper reports a case of pregnancy complicated with extraperitoneal Ewing sarcoma. Due to lumbosacral pain, a healthy full-term live female infant was successfully cesarean section in the First Hospital of Lanzhou University, who had previously received retroperitoneal tumor resection combined with left nephrectomy, supplemented with postoperative chemotherapy, combined with relevant medical history and examination to consider the recurrence and metastasis of extraperitoneal Ewing sarcoma. Because extraosseous Ewing sarcoma in pregnancy is very rare, the treatment is more difficult and the prognosis is poor. It is suggested that the suspected pregnant women should be followed up on the basis of regular prenatal examination in clinical work to find the focus in time. Once diagnosed, treatment strategies should be developed under the multi-disciplinary joint management mode to help patients overcome the challenges posed by pregnancy associated cancer and minimize adverse outcomes.
