Extended curettage and heat ablation for desmoplastic fibroma of the distal femur with a 12-year follow-up period: A case report

Desmoplastic fibroma is a particularly rare, benign but locally aggressive, primary bone tumor. Owing to previously published reports stating high recurrence rates following curettage, the recommended primary treatment for desmoplastic fibroma is a marginal to wide tumor resection. In the current report, the case of an athlete with desmoplastic fibroma of the distal femur who was treated with extended curettage, heat ablation and artificial bone grafting is described. The postoperative course was uneventful and no recurrence has been observed during the 12-year follow-up period. The patient is able to sit on his heels with a straight back, without pain and is able run a complete marathon.
