CasePresentation Chondromyxoid fibroma (CMF) is a relatively rare bone tumor of cartilaginous origin and it comprises less than 1% of all primary bony tumors. Clavicle is an unusual site of involvement for any bone tumor and may produce diagnostic dilemma. Approximately only 1% of all primary bone tumors may involve the clavicle. The literature on clinical features and outcome of CMF clavicle remains sparse.

Conclusion We present an unusual case of CMF clavicle in which the medial aspect of the clavicle gradually disappeared on radiographs. CMF should be included in the differential diagnoses of disappearing bone disease.
