case_images: Tumor cells were mostly spindle cells, but occasional bizarre nuclei and very rare mitotic figures (less than 1/10 high power field) were also observed. A preoperative CT scan on admission showed a large, homogenous, smoothly outlined, low-attenuation tumor mass in the pelvis, close to the ascending colon (Fig. 1).
case_images: Gross findings of the specimen revealed multiple yellowish capsulated mass measuring up to 12 x 11 x 5 cm. The mass was located in the subserosa of the ascending colon.

case_images: Two ulcerated lesions involving the tumor (meaning is unclear) were observed in the colonic mucosa (Fig. 2).
case_images: Microscopic findings consist large pleomorphic cells, highly vacuolated and lipid rich cells, and lipoblats (H&E, x400).

case_images: These findings were consistent with pleomorphic liposarcoma (Fig. 3), and the tumor was determined to be of histological grade 2, according to the FNCLCC system.
