title: Case report 826: Physiological resorption of allograft simulating recurrent giant cell tumor.
abstract: A case of focal resorption in a limb salvage/bone allograft is presented, illustrating that roentgenological differentiation from other causes for graft resorption may be very difficult. The possibilities of infection and tumor recurrence, as well as "physiologic" graft resorption, must be considered in the differential diagnosis of a lytic process in an allograft for limb salvage. To date, early biopsy remains mandatory for accurate diagnosis.
