“…Osteochondromas become evident mainly between the ages of 10-20 years with a slight male preponderance. Osteochondromas rarely become symptomatic after attainment of skeletal maturity; however, secondary impingement of soft tissues (tendons, nerves, vessels), fracture through the stalk, pseudoaneurysm formation, infection, ischemic necrosis, and malignant transformation may result in appearance of symptoms in adults [8][9][10][11][12]. After attainment of skeletal maturity, there is cessation of growth of most osteochondromas [2] or a very small amount of growth can still occur after physeal closure [13].…”

Giant osteochondroma of proximal fibula in a skeletally mature patient

Osteochondroma are believed to be most common benign tumors. The growth of osteochondroma usually ceases when skeletal maturity is reached but becomes a matter of concern to the attending doctor if the lesion becomes painful and shows evidence of increased growth even after physeal closure, which may be an indication of sarcomatous change in the lesion. We present a case with substantial growth of an osteochondroma after attainment of skeletal maturity. The tumor turned out to be histologically benign, and patient had an uneventful recovery with no recurrence.

The Foot and Ankle Online Journal 3 (10): 3Osteochondroma are believed to be most common benign tumors accounting for 36% to 41% of all such tumors. We report a rare occurrence of such a tumor in distal interosseous space of leg. In our case osteochondroma arising from distal fibula invaded the interosseous space and produced pressure effects on tibia. We believe this may be the first reported case of distal fibular osteochondroma producing pressure effects on the tibia. The tumor was excised using a transfibular approach and osteotomy site fixed with a semitubular plate.

“…The varied descriptions of this tumor have included comparisons to a normal osteochondroma, a low-grade chondrosarcoma, and a conventional dedifferentiated chondrosarcoma [19, 20]. The purposes of this investigation were to quantify and describe the radiographic findings of a large series of patients with peripheral dedifferentiated chondrosarcomas to determine whether this tumor has a distinct, recognizable radiographic appearance.…”

Introduction. Peripheral de-differentiated chondrosarcomas are among the rarest malignant mesenchymal tumors. This tumor's descriptive radiographic characteristics are reported but objective quantification does not exist. This investigation surveyed imaging of peripheral de-differentiated chondrosarcomas to facilitate better recognition of these uncommon tumors. Methods. Database interrogation for peripheral de-differentiated chondrosarcomas was performed; 23 patients were identified and imaging for 18 was reviewed. A musculoskeletal radiologist reviewed all studies for mineralization characteristics; presence of pre-existing osteochondromas; preserved corticomedullary continuity; adjacent cortical obliteration; soft-tissue mass; tumor necrosis; and presence of a cartilage cap. Tumor luminance was measured with computer software. Results. Mineralization was present in 17 tumors. Pre-existing exostoses were evident in nine cases, corticomedullary continuity was preserved in three cases. There was no difference in mineralization or other characteristics based on tumor location. Mean tumor luminance was 94.9 candela/m2. Conclusions. The imaging characteristics described for central de-differentiated chondrosarcomas are similar to the peripheral form of this tumor. Peripheral mineralization with a bimorphic pattern on CT scan and the presence of a soft-tissue mass should be considered worrisome for a peripheral de-differentiated chondrosarcoma, particularly in the setting of multiple hereditary exostoses.
