A well-circumscribed mass lesion measuring 11 × 8 cm in dia. was found at the retroperitoneum. The mass lesion was slightly enhanced by contrast medium. b: T1-weighted MRI (in-phase) image. c: T1-weighted MRI (opposed-phase) image. No fat component was found in the mass lesion. Figure S2. Cut surface of the resected specimen. The tumor was elastic, hard, well-defined and yellowish-white-colored. Figure S3. a: No atypia was observed at adipocytes surrounding the tumor (HE ×100). b, c: Photographs of immunohistochemistry of p16 (b) and MDM2 (c, performed at Kyushu University). The tumor cells with mild nuclear atypia expressed p16, and MDM2, respectively. d: Expression of CDK4 was not observed at the surrounding adipose tissue (×40). Table S1.
