Mayo Clinic PathWays: What’s the diagnosis?

This week's case reviews right lower extremity images and slides of a 58-year-old man who presented with a growing, painful mass involving his right lower thigh. Pertinent clinical information included short stature, limb-length discrepancy, multiple enchondromas (a type of benign bone tumor that originates from cartilage) and a hemangioma (a benign tumor of blood vessels, often forming a red birthmark) removed from his arm a few years ago. Can you make the diagnosis?
