Multimodality treatment of a multifocal osteoblastoma-like tumor of the lower extremity

Skeletal Radiol. 2012 Sep;41(9):1153-61. doi: 10.1007/s00256-011-1345-6. Epub 2012 Feb 13.

Abstract

Osteoblastoma-like tumor is a rare condition with limited information on its orthopedic management in the current medical literature. The tumor histologically resembles an osteoblastoma, although the radiographic features are similar to those observed in primary vascular lesions. The treatment in the previously reported cases involved aggressive procedures including amputation, en bloc resection, and chemotherapy because of the uncertainty regarding the biological behavior of the tumor. We present a case of this entity that was successfully treated by a combination therapy including intralesional curettage with adjuvant cryotherapy, in situ and intravenous administration of bisphosphonates and radioablation.
