Giant retroperitoneal liposarcoma : a case report 

Abstract Background: Giant dedifferentiated liposarcoma in the abdomen is a rare and aggressive malignancy and poses significant challenges in clinical management. Case presentation: A 48-year-old female presented with a sudden increase in abdominal size. Ultrasonography and MRI performed at our hospital revealed a massive abdominal mass with undetermined characteristics. The patient underwent a mass excision surgery at our hospital and had a good postoperative recovery. The pathological examination revealed dedifferentiated liposarcoma. Conclusions: The sudden enlargement of an abdominal mass should raise our attention, as the treatment and diagnostic criteria for dedifferentiated liposarcoma pose challenges. It requires clinical doctors to pay close attention to the condition.
