Histiocytic fibroma of bone (a study of 170 cases)

This study is based on 170 cases of histiocytic fibroma of bone. This is a metaphyseal hamartoma composed of histio-fibroblasts; it is completely benign, and affects children and adolescents. Because of their benign nature and characteristic radiographic appearance, which is almost always diagnostic, these tumours do not require surgery, except in rare forms that give rise to symptoms, or in which tthe radiographic appearances are atypical and clarification of the diagnosis is called for.
