Chondromyxoid fibroma of calcaneus

Chondromyxoid fibroma is a rare benign primary bone tumor composed of immature myxoid mesenchymal and cartilaginous tissue. Its occurrence in calcaneus is very rare and few cases of calcaneal involvement have been reported in literature. We report five cases of CMF in calcaneus.

Five cases, with the final diagnosis of chondromyxoid fibroma of the calcaneal bone are included in this report. Preoperative tumor workup was performed for our patients. We reviewed and recorded demographic data and the sign and symptoms of patients at presentation to our center. Mode of treatments, postoperative complications and recurrence were also studied. Curettage, high speed burring and bone grafting was performed in 4 of our patients and in the remaining case we only carried out curettage and burring.

Of the five patients, 3 were male and 2 were female. The mean age at presentation was 21. Two of our cases had previous surgery in other centers and had been referred to our clinic because of recurrence. The chief complaint in all of our patients was heel pain. The mean follow up period was 25.2 months. All of our patients had a delay in the diagnosis of tumor. We did not have any recurrence in our patients during follow up period.

This case series shows that chondromyxoid fibroma is not necessarily as exceedingly rare as generally reported in the current literature. This tumor should be considered in the differential diagnosis in patients with ankle and heel pain.
