Chondromyxoid fibroma of the femur in a child aged 9 years (Clinical case)

The article reflects the experience in the diagnosis and surgical treatment of chondromyxoid fibroma in the proximal metadiaphysis of a large femoral bone in a child in the first decade of life. We presented the family and medical history of the child complaints, orthopedic/local status, and the results of radiological methods and emphasized difficulties of nosologic identification and differential diagnosis of the bone destructive process at the stage before biopsy and surgery. Macroscopic findings during surgery were identified, and the amount of resection of the affected bone was determined. A detailed description of the results of pathological and morphological (macro- and microscopic) studies is given, which could confirm the tumor process. Late results with the absence of oncological re-occurrence (7 years) and good anatomical and functional results from orthopedic surgery are shown.
