Chondrosarcoma of the foot

Chondrosarcoma is a rare malignant cartilaginous tumor of the bone. It commonly occurs in the pelvis, proximal femur, and shoulder girdle. We present a case of a woman in her mid-50s with chondrosarcoma of the foot--a rare lesion that accounts for 0.5% to 2.97% of all chondrosarcomas. Distinguishing a chondrosarcoma of the foot from an enchondroma can prove difficult because of the greater cellularity and atypia that is allowable for enchondromas of the foot compared with those of other sites. There must be a combined clinical, radiographic, and histologic diagnosis. Treatment for chondrosarcoma is generally wide surgical excision. Chemotherapy or traditional radiation is not effective for most of these lesions.
