Successful outcome of a surgically treated giant retroperitoneal liposarcoma during pregnancy

Retroperitoneal liposarcomas occur more frequently between the fifth and seventh decades. Fortunately, these tumors are exceedingly rare in pregnancy, but when they occur, their management becomes even more challenging.

A pregnant patient with a retroperitoneal liposarcoma was treated by complete surgical resection at 13 weeks of gestation. The patient gave birth at 37 weeks of gestation to a normal newborn and remains free of disease after a year.

Individualized approach should be taken according to gestational phase, tumor kinetics and overall patient's condition. Any disturbance to materno-fetal equilibrium, should be an indication for urgent therapeutic approach.
