Juxtacortical Chondromyxoid Fibroma of Bone: A Unique Variant

Abstract

CMF should be included in the differential diagnosis of bone surface lesions. The clinical and radiologic findings must be known. The morphology of this lesion is similar to conventional CMF with the exception of focal exuberant calcification. Conservative therapy is the treatment of choice.

Imaging features of chondromyxoid fibroma: report of 15 cases and literature review

“…In older patients, lesions are more frequently seen at rare localizations. [16][17][18][19][20][21][22][23] In our study group, three patients were diagnosed in the fifth and one patient in the sixth decade of life. However, these lesions did not appear in atypical localizations.…”

“…facial and skull base CMF). [10][11][12][13][14][15][16][17][18][19][20] Our goal was to analyse the histopathologically proven CMF cases in University Hospital Leuven, focusing on imaging landmarks which can help us in the diagnostic work-up and to compare these with the published literature.…”

Juxtacortical Chondromyxoid Fibroma of Tibia

“…In a series of patients which include six sub periosteal CMF; four out of six patients were older than 30 years [4]. In another series, 13 out of 20 patients with Juxtacortical CMF were older than 30 years [8]. This is in contrast to the conventional CMF which usually presents before the age of 30 [2].…”

“…Juxtacortical CMF very commonly occurs in male gender [4]. In a study including 20 patients with Juxtacortical CMF, only 40% of them were female [8]. In another study including six patients with superficial CMF were male [4].…”

Chondromyxoid Fibroma with Secondary Aneurysmal Bone Cyst of the Rib

“…In the remaining cases, CMFs have been detected in the pelvis, ilium, or the small bones of the hands and feet. 1,[4][5][6] CMF of the rib is very rare. Recent studies suggest that aberrations in chromosome 6q13-21 are associated with local aggressiveness in cartilaginous tumors.…”
