Chondrosarcomata seldom occur in the foot, the total reported experience comprising only twelve cases. The average age of the patients is thirty-eight years, with eight males and four females being affected. The symptoms are usually pain and swelling, with an average duration of fifteen months. Roentgenograms demonstrate. a poorly defined lytic lesion with destruction of the cortex and extension into the soft tissues. Spotty calcification is often present in the lesion. On gross examination the tumor is generally lobulated, and microscopically the cells show variation in size and shape, bizarre nuclei, and multinucleated malignant chondrocytes. The treatment is ray resection or en bloc excision, depending on location. The prognosis of this malignant tumor is good, three of ten patients having survived five years or longer.
