Chondromyxoid fibroma


Chondromyxoid fibroma very seldom found hryashcheobrazuyushchy tumor allocated in an independent form in 1948 to Jaffe and Lichtenstein. The tumor is inclined to a frequent recurrence and in certain cases an ozlokachestvleniye.

Symptoms of Chondromyxoid fibroma:

Chondromyxoid fibroma is localized in metaphyses or a metadiaphysis of long tubular bones, preferential near a knee joint. Also chondromyxoid fibromas of ossicles of a brush and feet, pelvic bones are described.

The clinical picture of chondromyxoid fibroma depends on age of patients. Progressive strengthening of pains, rapid growth of a tumor, restriction of movements in a nearby joint, the accruing muscular atrophy, a local hyperthermia are characteristic of children's age.

The X-ray pattern is presented in the form of the center of destruction reaching in length of 4-5, 6-8 cm. Sometimes the center of destruction is surrounded with a sclerous rim, against the background of the center of destruction the trabecular drawing and impregnations of lime can be traced. At subperiosteal localization of the center the uzuration of a cortical layer comes to light, the tumor goes beyond a bone. Periosteal reaction is not typical.

The greatest difficulties arise at differentiation of a benign cartilaginous tumor from malignant. Jaffe notes that for the diagnosis of chondromyxoid fibroma it is necessary to use "sixth sense", connecting the minimum impressions in a single whole. Judging by data of literature, diagnostic mistakes are made and now towards hyper diagnosis of sarcomas. All cases have to be verified morphologically.
