title: Chondrosarcoma of the talus: a case report.
abstract: Although malignant cartilage tumors of the foot and especially of the talus are uncommon, the treating physician must become suspicious when a "simple ankle sprain" is resistant to standard treatment. In such a case, the comparison of serial radiographs may reveal subtle changes and the use of a radioactive bone scan may be of diagnostic value.
