A common benign tumor presenting with two rare complications

Osteochondromas are the most common benign tumors of the bone. Osteochondromas presenting with vascular complication and also showing malignant transformation is very rare. Our patient presented with the combination of these two rare complications (gangrene of foot and a low grade secondary peripheral chondrosarcoma). Literature review shows local recurrences with aggressive behaviour are likely with these low grade tumors if not removed adequately and suggests for en-bloc resection.
