Giant-cell tumor of bone in skeletally immature patients

Giant-cell tumor of bone is predominantly an affliction of adults and is rarely found in skeletally immature patients. We are reporting six new cases of histologically confirmed giant-cell tumor of bone in patients with radiographically open epiphyseal plates. These patients account for 1.8 per cent of the 326 giant-cell tumor of bone observed at the Bone Tumor Center of the Istituto Ortopedico Rizzoli in Bologna, Italy.
