The imaging of CT scanning indicated for the second and third recurrence of the female patient in July 2010 and November 2011, respectively. (A) The giant tumors with adipose density occupied almost the entire abdominal cavity (July 2010); (B) The tumors originated from the hepatic hilar region and oppressed adjacent organs and tissues (November 2011).

The abdominal and pelvic CT revealed multifocal, class-round tumors originating from the hepatic hilar region and oppressing the adjacent intestinal canal, caudate lobe, inferior vena cava (IVC), and aorta abdominalis (Figure 1B); another mass was located in the middle and lower abdomen; the tumors were all enhanced inhomogeneously; the left kidney was displaced anterior to the intraperitoneal cavity; and a class-round tumor and low density existed in the right ovary but was not enhanced, which was diagnosed as a recurrence of multifocal RPLS.
The gross appearance of the totally excised tumors presented in the operation (July 2010). (A) The giant tumor shaped like lobulated or dumbbell (measured 45x30x20 cm) with rich blood supply; (B) The multifocal tumors were well-encapsulated with macroscopic safe margins. The histopathological presentations of the tumors originated from the retroperitoneum and the tumors infiltrated the stomach (July 2010). (C) The retroperitoneal tumors were diagnosed as dedifferentiated liposarcoma; (D) Tumors of the stomach were diagnosed as sclerosing liposarcoma, dedifferentiation in focal areas.

All tumors were well-encapsulated and completely removed with a concomitant part of the gastric wall (Figures 2A, B). The lip blasts with abundant vessels were in focal areas (diagnosed as sclerosing liposarcoma, dedifferentiation in focal areas) (Figures 2C, D).
The timeline shows that the patient underwent operation four times and experienced recurrences, respectively, and 15 years of follow-up in all.
