[Fibroma chondromyxoides in two children--a case study]

The authors present the results of treatment of 2 cases of fibroma chondromyxoides in children. In Polish orthopaedic literature only 2 other cases have been presented. The first case--a 13-year-old boy--was referred to our centre because of a recurrent tumour in the 1st metatarsal bone and surrounding soft tissues. The boy had received treatment 3 years earlier outside our centre, where curettage of the tumour was performed. The bone cavity was then filled with bone grafts. The tumour was removed again and autogenous bone grafts were applied. On follow-up 7 years after surgery no recurrence was noted, along with full remodelling of the bone grafts. The second case was a 9-year-old child. The tumour was localised in the proximal phalanx of the thumb. During curettage and application of autogenous bone grafts for the tibia, transplantation of the tumour site occurred to the donor site. Two years after surgery tumour recurrence was observed. A re-operation was performed, with complete resection of the basal phalanx, with a fibular graft implantation. The tumour in the tibia was also removed. Two and a half years after surgery both tumour sites remain free of signs of recurrence.
