Enchondromas are the most common benign cartilaginous bone tumors of the toe. In contrast, chondrosarcomas are very uncommon in the foot. We report an unusual case of a chondrosarcoma arising in the great toe. The patient was a 62-year-old woman whose chief complaint was swelling of her left great toe. Radiography showed subtle punctate calcification and mild sclerosis and irregularity of the distal phalanx in the great toe. Magnetic resonance imaging showed extraskeletal growth. The distal phalanx was amputated. Histologic examination demonstrated a grade 1 chondrosarcoma. Two years after surgery, the patient was free of recurrence and lung metastasis.
