A rare location of the rare tumour-chondromyxoid fibroma of calcaneum

Abstract

Chondromyxoid fibroma (CMF) primary location is the long tubular bones of the lower extremity followed by foot and knee. This benign cartilaginous tumor of bone is the rarest reported neoplasm of cartilaginous origin. This mass can mimic other benign and malignant bone tumors owing to its variable histologic features. We report a case of CMF of the calcaneum with varying presentations. Pathologic examination is difficult but can be used to differentiate this lesion from more serious conditions. A quick and accurate diagnosis of CMF can prevent unnecessary treatment that could be harmful to the patient.
