Similar to enchondroma
it is a lesion arising in medullary cavity with irregular matrix calcification, but chondrosarcomas have a more aggressive appearance with bone destruction, cortical erosion, periosteal reaction and rarely a soft tissue mass.
Chest wall secondary chondrosarcoma arising from enchondroma
in a young Asian female.
The differential diagnosis of fibrous dysplasia includes lesions like Paget's disease, Non ossifying fibroma, Simple bone cyst, Enchondroma
, Adamantinoma, Aneurysmal bone cyst, Osteofibrous dysplasia, Diffuse sclerosing osteomyelitis and Giant cell tumour.
Benign osseous lesions in the hand and fingers far outnumber malignant lesions, with enchondroma
being the most common.
Biopsy of the lesion was consistent with the clinical impression of enchondroma
He was evaluated with a right knee MRI that showed an anterior cruciate ligament (ACL) tear and a small subcortical lesion at the posterior aspect of the medial metaphysis of the distal femur that was nonspecific and too small to characterize; however, enthesopathy and small cortical based lesions such as nonossifying fibroma, enchondroma
, fibrous cortical defect, and fibrous dysplasia were included in the differential diagnosis (Figure 1).
Third decade Diaphysis of the long M = F bones of the hands and feet, proximal femur, and humerus.
Although unlikely, malignant tumors such as osteosarcoma and Ewings, and benign tumors in the form of osteoid osteoma and solitary enchondroma
were also considered (7).
Differential diagnosis may include TB pyogenic infections metastasis and benign bone tumors (fibrous dysplasia enchondroma
They reported findings consistent with ossified enchondroma
after post-surgical histopathological examination of the dissected material.
Regeneration of an enchondroma
defect under the influence of an implant of human bone morphogenetic protein.
Differential diagnosis includes expansile lytic lesions of bone, such as aneurysmal bone cyst, simple bone cyst, enchondroma
and fibrous dysplasia, as well as giant cell tumour if the lesion is situated in the epiphysis.
