case_images: Magnetic resonance imaging revealed a tumor mass measuring 13 x 15 x 24 cm located in the left posterior thigh. Almost all the muscles, except the rectus femoris, sartorius, and gracilis muscles, show lipomatous changes. T1- and T2-weighted images (WIs) T2-WI, and short-TI inversion recovery (STIR) images show high intensity. Coronal T2-WI (a), T1-WI (axial view) (b), T2-WI (axial view) (c), and STIR images (axial view) (d).

case_images: Magnetic resonance imaging (MRI) revealed high signal intensity on T1- and T2-weighted images and heterogeneous hyperintensity on short-TI inversion recovery images (Figure 1).
case_images: Macroscopic appearance of the resected tumor. The mass includes the semitendinosus muscle, semimembranosus muscle, and biceps femoris muscle.

case_images: We performed marginal resection including the semitendinosus muscle, semimembranosus muscle, and biceps femoris muscle (Figure 2).
case_images: Pathological findings show mature adipocytes with cellular atypia and marked variations in size and shape. Hematoxylin-eosin staining, x25. Scale bar, 1 mm.
