Fibrous Tumours of Bone
摘要
Only two entities are considered “fibrogenic tumours of bone” in the latest World Health Organisation classification of soft tissue and bone tumours; these are desmoplastic fibroma of bone and fibrosarcoma. It is recognised that fibrous components are observed in a diverse group of skeletal lesions depicted by areas of fibroblastic cell proliferation and a collagen-rich matrix, including fibrous dysplasia, osteofibrous dysplasia, and nonossifying fibroma. While many benign entities are asymptomatic and discovered incidentally through imaging, some may present clinically with pathological fractures or deformities. Radiological appearances often allow confident characterisation of lesions as benign, which is important to avoid unnecessary biopsy. More aggressive or atypical lesions necessitate advanced imaging and often histopathological confirmation. This chapter offers a practical guide for the recognition of both “fibrogenic” tumours of bone but also several other bone tumours with fibrous elements. It also covers recent changes, and up-to-date nomenclature for these lesions.
