Osteoblastoma of the Distal Radius.

Abstract

Osteoblastomas are rare, benign, bone-forming neoplasms that represent less than 1% of all bone tumors and occur mostly in people aged 10 to 30 years. In long bones, the metadiaphyseal region tends to be most commonly affected. However, to the best of our knowledge, only 11 cases have been reported to occur in the distal radius. We present the clinical, radiological, and histopathological findings of an osteoblastoma of the right distal radius in a 42-year-old woman for whom an open excisional biopsy with nidus removal comprised the treatment and produced a good outcome.
