Summary
This tumor occurs in the metatarsals and phalanges.
Complete Information on this Tumor
Approximately 8% of these tumors occur in the bones of the foot. Small, peripheral cartilage tumors tend to be benign, where as large central cartilage lesions are more likely to be malignant. Reliable differentiation of benign from malignant cartilage tumors is difficult. Tumors that are larger, tumors located in the hindfoot or midfoot, or new tumors presenting in a patient with a known history of enchondromatosis (Ollier's disease) have an increased risk of malignancy.
Patients present with pain during activities or after an injury, but there is rarely any mass palpable on physical examination. For enchondromas in the phalanges, pathological fracture through the lesion will cause the patient to seek medical care. A few patients have multiple enchondromas and warrant special attention and possibly referral to a bone tumor specialist.
