Allograft bone in the treatment of desmoplastic fibroma. A case report.

A 17-year-old girl had a desmoplastic fibroma of the distal femur. This rare tumor is managed by surgery alone and requires a marginal to wide resection because of its high risk of local recurrence. Had the tumor invaded into the epiphysis and marginal resection, it would have resulted in loss of articular femoral condyle. It was treated by en bloc proximal resection with distal intralesional curettage and anatomic specific allograft femoral replacement. There was no recurrence of the tumor three years after surgery, and function was excellent.
