title: Extraskeletal chondroma of the foot.
abstract: Extraskeletal chondroma is a rare, benign cartilaginous tumor seen most frequently in the soft tissues of the hands and feet. The authors present a case of extraskeletal chondroma in a 52-year-old male patient who had a small mass on the left foot involving the flexor surface of the second toe. Radiographs showed the presence of a soft-tissue mass with scattered calcified foci. Surgical excision revealed a benign, lobulated cartilaginous tumor with prominent areas of calcification. Histologically; the lesion consisted of cartilage cells with centralized zones of cellular pleomorphism and giant-cell proliferation at the tumor margin consistent with extraskeletal chondroma.
