Differential diagnosis of benign pediatric bone tumors

Approach to the differential diagnosis of benign bone tumors:

  • Location (diaphysis, metaphysis, epiphysis, abut articular surface)
  • Lytic or blastic
  • Matrix (chondroid, osteoid, fibrous)
  • Zone of transition (wide, narrow)
  • Periosteal new bone and / or cortical destruction

In general, benign bone tumors tend to have a narrow zone of transition with no periosteal new bone formation or cortical destruction
