Summary

Chondroblastoma is a rare benign bone tumor, most often located in an epiphysis. It represents about 1 % of all benign bone tumors. Chondroblastoma is typical for young patients and occurs most often in the second decade of life. Clinical presentation consists of pain and restriction of movement in the affected joint. Histology shows a benign type of tumor, which can however grow aggressively and destroy its surroundings (spongiosa, cortical bone and joint cartilage) and expand into the joint cavity. Tumor cells produce cytokines, which are responsible for inflammatory processes occurring around the tumor such as bone edema or prominent synovitis in case of intraarticular growth. In 20 % of cases, we see a relapse despite treatment. In this article we present the case of a 15-year-old boy with a proximal femur chondroblastoma. After the initial biopsy, the tumor was treated surgically via surgical hip dislocation, which allows treatment of the femoral head without compromising nutritional blood vessels. After a radical excochleation and local chemoproteolysis, the defect was filled with partially resorbable bone cement. The patient has been monitored for a year now with a good clinical and radiological outcome.
