Desmoplastic fibroma is a rare benign tumour of bone. Diagnosis is not easy and is often made by excluding other tumours. Histopathological diagnosis of this tumour is also sometimes not easy. The treatment modalities for this tumour are non-uniform and often controversial. In the present case surgical options were left aside because the patient did not consent to surgery, so radiotherapy was used, with success at 3-year follow-up. This case is presented here along with a review of relevant literature.
