Summary
Osteochondromas is a common benign bone tumor developing in the epiphysis of a long bone. It is characterized by cartilage-capped bony outgrowth (exostoses) on the surface of bones. Osteochondromas most commonly affect long bones in the leg, pelvis, or scapula. Even though it's a benign tumor, it can present with complications like pathologic fractures, bone malformation, or compression of nearby neurovascular structures.
