Chondromyxoid fibroma of the foot.

Chondromyxoid fibroma is a rare benign cartilaginous tumour seen most frequently around the knee in children and young adults. Up to 17% occur in the foot, where more aggressive appearances have been reported. Four cases of chondromyxoid fibroma in the forefoot are presented, demonstrating the wide range of radiological appearances of this primary tumour. Three of the four tumours recurred, one at 19 years after the surgery. These cases illustrate the need for thorough preoperative assessment to ensure complete surgical resection in an attempt to reduce the incidence of local recurrence.
