Chondromyxoid fibroma (CMF) is a rare, benign and potentially aggressive cartilage forming bone tumour and accounts for less than 1% of primary bone tumour. It usually affects the metaphysis of long bones in first or second decades of life. It occurs in males more often than females. Because of rarity of CMF and its varied morphology, it can be confused with malignant tumour and adds difficulty in diagnosis. Herein, we report a case of CMF in a 32 year old female involving the proximal end of tibia.
