Desmoplastic fibroma of bone is an extremely rare locally aggressive primary bone tumour. Diagnosis is tricky and treatment experience limited with tumor surgeons. We studied three rare cases of desmoplastic fibroma arising primarily in bone at unusual sites. Diagnosis was established by radio-histopathologic correlation. Patients were operated with various modalities. Results were evaluated over long term follow-up (6-9 years). The disease was eradicated in all the three cases and no recurrence was seen over long term follow-up. Functional outcome was good and no complications were encountered. Wide resection of the tumor is favoured as the recurrence rates after surgical treatment are high.
