General
- Common
- Non-neoplastic
- Self-limited
- Skeletally immature individuals, children and adolescent
- Often small lesions discovered an radiographic incidentaloma
Synonyms
- Nonossifying fibroma (larger but otherwise identical)
- Fibrous cortical defect
- Fibrous metaphyseal defect
- Fibroxanthoma of bone
Site
- Metaphysis of distal femur or proximal tibia (80%)
- Cortical
- Metaphysis
- Long bones
- Eccentric location
Gross
Firm, granular, brown to yellow to red
Microscopic
Spindle cells without cytologic atypia are arranged in a storiform pattern with scattered chronic inflammatory cells and benign giant cells. Foam cells and hemosiderin deposition are present. Mitoses are seen but cytologic atypia is absent.
Differential Diagnosis
- Giant cell tumor of bone (epiphyseal location, occurs in adults)
Relevant Diagnostic Groups
- FOG MACHINES - acronym for radiographically lytic bone lesions <ref {{http://radiopaedia.org/articles/lytic-bone-lesion-mnemonic}} /ref>
- Giant cell lesions of bone.
- Spindle cell lesions of bone.
