A 56-year-old male patient underwent surgical resection of retroperitoneal LPS. On the preoperative PET/CT scan (A), a hypermetabolic solid mass and a fatty mass with no FDG uptake located on the medial side were detected. A solid LPS was resected (B) and confirmed as DDLPS with FNCLCC grade 2 (C,D). However, the 1-week postoperative CT revealed remnant fatty mass on the medial side (E). After reoperation, the fatty mass was confirmed as WDLPS, FNCLCC grade 1 tumor (F). CT scan performed 8 months after the initial operation revealed peritoneal carcinomatosis with a relatively solid mass (G,H). The patient died 4 months later. Arrowhead indicates DDLPS, arrow indicates WDLPS, red dotted line indicates solid tumor with peritoneal carcinomatosis. DD dedifferentiated liposarcoma, WD well-differentiated liposarcoma, TE tissue expander.
