[Benign osteoblastic neoplasias of bone: clinical and anatomoradiological correlations between osteoid osteoma and osteoblastoma (author's transl)].

The clinico-radiologic and histopathologic features of 40 osteoid osteomas and 12 osteoblastomas are compared. The authors conclude there are no significant differences between these two tumors except for the size of the neoplastic area and the degree of evolution of the neoplastic tissue.
