Figure 2: (a) Gross photograph of en bloc excised autopsy specimen shows a large, well-circumscribed, encapsulated, bosselated tumor on the right side. Right lung and other mediastinal structures appear compressed by the tumor. (b) Low power view of the tumor showing islands of cartilage, surrounded by sheets of undifferentiated mesenchymal cells (H and E; ×40). (c) Undifferentiated mesenchymal cells arranged in hemangiopericytomatous pattern (H and E; ×100). Inset: mesenchymal cells showing scant cytoplasm and hyperchromatic nuclei (H and E; ×400). (d) Island of cartilage surrounded by small round cells (H and E; ×200)
