title: In-situ chondrosarcoma of the foot arising in a solitary enchondroma.
abstract: Chondrosarcoma of the foot is very rare. Secondary malignant transformation of a solitary enchondroma of the foot occurring in a 66-year-old man is reported. A rapid increase in size of a previously known enchondroma and pain may suggest a malignant transformation. Surgical resection is the choice of therapy.
