Anterior chest wall mass in an elderly male.
A case of chondrosarcoma arising from the right anterior second rib in an 84-year-old man is described. Radiographic features include amorphous calcification within a chest wall mass. CT findings include calcification and necrosis within the 8 X 8 X 10 cm tumor, and extension into the adjacent lung. The presence of zones of dedifferentiation into fibrosarcoma in the surgically resected tumor indicates a poor prognosis, with a high likelihood of early recurrence and pulmonary metastasis.
