Abstract
Background: Chondromas constitutes approximately 25% of all benign bone tumours and 35-58% occur in short tubular bones of hands and feet but large chondroma of long bone like femur is very rare. Chondromas are characterized by formation of mature hyaline cartilage. Enchondroma is the chondroma arising from within medullary cavity.
Result: Our patient is an elderly female presented with swelling and pain in left knee underwent Curettage and bone cementing. Bone cementing to prevent pathological fracture during physiological loading.
Conclusion: Malignant transformation to chondrosarcoma although rare but can occur. Lytic lesions in weight bearing long bone like femur requires early diagnosis and timely intervention.
Keywords: Enchondroma, Chondrosarcoma, Curettage, Bone cementing.
