Macroscopic appearance of the myxoid liposarcoma: a dark purple smooth mass measuring 12.5 x 11 x 6 cm that weighs 326 grams similar to splenic tissue. The black arrow indicates the stalk by which the liposarcoma was attached to the pelvic wall.

However, a dark purple, smooth pelvic mass was found attached to the pelvic wall by a small stalk with similar macroscopic appearance to that of splenic tissue (Figure 1).
(a) Haemorrhagic infarcted tissue with background myxoid material and some viable cells identified at the periphery (haematoxylin-eosin, 10x). (b) Both lipoblasts and round cells at the periphery of the tumour (haematoxylin-eosin, 40x).

Histology confirmed a recurrence of the previous myxoid liposarcoma (Figure 2).
Frontal (left panel) and transverse (right panel) views of the CT scan performed postoperatively. A well-defined oval hypodense uniform mass is appreciated at the right iliac fossa measuring 10 x 8.4 cm with a central rounded higher density soft tissue area within it (white arrows).

One month later a CT scan of the chest, abdomen, and pelvis showed a new well-defined oval hypodense mass in the right iliac fossa adjacent to the anastomotic surgical sutures site that was suspicious for recurrence (Figure 3).
