The patient was a 73-year-old man. After receiving the diagnosis of abdominal distension and renal impairment at a nearby clinic, he was referred to our hospital for further detailed examination. He exhibited hypercalcemia associated with paraneoplastic syndrome, and abdominal CT scans showed a 37 cm mass in the abdominal cavity. He was diagnosed as having a giant intraperitoneal tumor and underwent laparotomy to improve his quality of life. The tumor was considered to have originated around the iliopsoas muscle, and was completely resected macroscopically. The tumor weighed 9.1 kg, and its fluid content was brown with a volume of 12,200 mL. The tumor was confirmed histopathologically to be a dedifferentiated liposarcoma. We report this case of a patient with a giant dedifferentiated liposarcoma with hypercalcemia and provide a review of the relevant literature.
