It exhibits a bimodal age distribution, most frequently arising during the adolescent and young adult growth spurt, with a secondary peak among older adults often linked to predisposing conditions such as Paget disease or prior irradiation Clinically, it typically presents with localized, progressive bone pain and soft tissue swelling, with a marked propensity for cortical destruction and hematogenous metastasis, particularly to the lungs

It exhibits a bimodal age distribution, most frequently arising during the adolescent and young adult growth spurt, with a secondary peak among older adults often linked to predisposing conditions such as Paget disease or prior irradiation The condition predominantly develops within the metaphyseal regions of long tubular bones, most commonly the distal femur, proximal tibia, and proximal humerus Clinically, it typically presents with localized, progressive bone pain and soft tissue swelling, wi...
