Figure 6. (A) Skin incision (thin solid line), L-shaped sternal division (thick solid line), and release of the sternal head and the clavicular head of the sternocleidomastoid muscle from its origin (dashed line) are illustrated. (B) Gross specimen and pathological findings. The tumor in the first rib was resected. The tumor (arrow) was covered by smooth pleura. (C) A microscopic view shows diffuse proliferation of short, spindle-shaped cells without nuclear atypia, as well as osteoid formation and extensive fibrosis throughout the entire specimen. No giant cells are observed (hematoxylin and eosin staining).
