Which primary bone tumors tend to involve the epiphysis most commonly?
Chondroblastoma and giant cell tumor (GCT) tend to involve the epiphysis most commonly. Chondroblastoma is a benign lesion that is typically well defined and located in the epiphysis, most often occurring in children and young adults. Although benign, chondroblastomas can be locally invasive and metastasize to the lungs.
A GCT usually arises in the metaphyseal region and extends to involve the epiphysis, most often in young adults. GCTs are eccentrically located lesions with a nonsclerotic zone of transition that occurs after closure of the growth plate. A clear cell chondrosarcoma may also occur in the epiphyseal region.
