Chondromyxoid Fibroma of Clavicle Presenting as Radiological Disappearance of Bone. Annals of the National Academy of Medical Sciences. 2023 Apr; 58(2): 109-1140379-038Xhttp://imsear.searo.who.int/handle/123456789/220213Case?Presentation 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.chondromyxoid fibromaclavicledisappearing boneJournal ArticleIndiaDepartment of Orthopaedic Surgery, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, IndiaDepartment of Orthopaedic Surgery, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, IndiaDepartment of Orthopaedic Surgery, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, IndiaDepartment of Radiodiagnosis, Maulana Azad Medical College and Associated Lok Nayak Hospital, New Delhi, IndiaDepartment of Pathology, GIPMER Associated with Maulana Azad Medical College, New Delhi, India
