Extra-skeletal Ewing sarcoma of the lumbosacral region in an adult pregnant patient: a case report.

Extra-skeletal Ewing sarcoma in pregnancy is rare. There is thus limited scientific evidence to guide clinicians in its complicated management, particularly within the context of early gestation. We therefore share our successful outcome in a 32-year-old pregnant patient, following a unique management strategy of complete aggressive surgical resection prior to neo-adjuvant therapy.
