Chest computed tomography revealed a soft-tissue density mass in the upper lobe of the right lung near the hilum, with bronchial obstruction in the anterior segment of the upper lobe and a patchy fuzzy shadow distally (Figure 1).
Histopathological and immunohistochemical characteristics of the MPTs. (A) Atypical elongated cells had considerable diversity in the lung metastatic tumors (haematoxylin and eosin staining, 100x). (B) Abundant osteoclasts and osteoid formation were observed (haematoxylin and eosin staining, 100x). Tumor cells were positive for CD10 (C) and SATB-2 (D; immunohistochemical staining, 200x). (E) The MPT (left) and pleomorphic liposarcomatous differentiation (right) were mixed without clear boundaries in the primary breast MPT (haematoxylin and eosin staining, 40x). (F) Tumor cells with pleomorphic liposarcomatous differentiation were positive for S-100 (right; immunohistochemical staining, 40x).

Some portions of the mesenchyme contained areas of osteoid formation (Figures 2A,B). Table 1 and Figures 2C,D. The pathological features of the primary breast tumor represented a mixture of phyllodes tumor and liposarcoma (Figures 2E,F).
