1. Figure 1. (a) Regional computed tomography (CT) showed two distinctive patterns of low and iso density mass. (b) Gross finding of the resected specimen displayed a yellow fatty tumor and white solid firm mass. (c) Microscopical findings showed the abrupt transition between two areas (magnification ×20). (d) One pattern was composed of well-differentiated liposarcoma containing lipoblast (magnification ×200). (e) The other was composed of pleomorphic-spindle cell sarcoma resembling malignant fibrous histiocytoma (magnification ×200).

2. Figure 2. (a) Axial T1 magnetic resonance imaging (MRI) of the left thigh showed the two distinctive mass of low-to-intermediate and high signal intensity. (b) Axial T2 MRI demonstrated the mass with heterogeneously high and high signal intensity, representing lipogenic mass and non-lipogenic mass in the adductor muscles. (c) Axial view of the resected specimen showed yellow lipomatous and yellow firm lesion. (d) Low-power of microscopical findings demonstrated an abrupt transition (magnification ×20). (e) Well-differentiated liposarcoma showing scattered lipoblast was found (magnification ×200). (f) Dedifferentiated area, mimicking the appearance of malignant fibrous histiocytoma, was found (magnification ×200).

3. Figure 3. (a) Axial T1-weighted image showed the medial lesion had homogeneously low signal intensity and the antero-lateral lesion had high signal intensity. (b) Axial T2-weighted image showed the medial lesion had heterogeneously high and the antero-lateral lesion had high intensity. (c) Regional CT showed the two distinctive patters composed of fatty tumor and sarcomatous change. (d) Axial view of the resected specimen demonstrated yellow adipose tissue and a white firm nodule. (e) Microscopically, there was the transitional area (magnification ×20). (f) High-power of microscopical findings demonstrated well-differentiated liposarcoma containing atypical lipomatous cell (magnification ×200). (g) The dedifferentiated part was similar to malignant fibrous histiocytoma (magnification ×200).
