Chondromyxoid fibroma

Chondromyxoid fibroma is a rare benign tumor derived from cartilage. The classic site of involvement is usually the metaphyseal ends of the long tubular bones, such as the tibia. The majority of these tumors are seen in the lower extremities during the second and third decades of life. Local recurrence of the tumor in bone is not uncommon, while soft tissue recurrence is less frequent. Most younger patients and those with recurrent tumors tend to have the mucinous type. This case is somewhat classic in nature. The tumor was originally seen in the second decade of life and was of the mucinoid type. Bone grafting was necessary because of the size and location of the tumor.
