Mandibular metastasis of an extraskeletal myxoid chondrosarcoma arising on the plantar surface of the foot: report of case.

: This paper presented a discussion of the initial appearance and atypical clinical course, histopathology, treatment, and prognosis of a case of extraskeletal myxoid chondrosarcoma that originated on the plantar surface of the left foot and that metastasized to the mandible. The clinical behavior of this neoplasm, as reported, is distinctively less aggressive and therefore thought to have a better prognosis than chondrosarcoma of bone. Contrary to the biologic behavior reported in the literature, however, our patient had a less than six-year remission from the neoplasm.
