case_images: Histopathology revealed a tumor having a lobular pattern of growth of spindle shaped and stellate cells, with abundant myxoid and chondroid intercellular material [Figure 2]. The lamellar bony trabeculae showed no significant pathology [Figure 2 inset].
case_images: The tumor lobules having a hypocellular center and a hypercellular periphery with scattered benign multinucleated giant cells (inset; H and E x400) and hemosiderin-laden macrophages; H and E x100

case_images: The lobules had a hypocellular center and a hypercellular periphery with scattered benign multinucleated giant cells and hemosiderin-laden macrophages [Figure 3].
case_images: One portion of the tumor showing cells with pseudomalignant features; H and E x100 (inset; H and E x400)
