Osteoid osteoma and osteoblastoma.

Abstract

In conclusion, while similar histologically, osteoid osteoma and osteoblastoma have the potential of being significantly different clinically. Osteoid osteoma tends to be a problem of pain and not of great oncologic significance. Osteoblastoma, on the other hand, has the potential for local bone destruction and aggressiveness as well as the rare occurrence of metastases. For this reason, the latter tumor needs to be respected from an oncologic standpoint and appropriate surgical excision performed.
