Differential diagnosis of bone tumors Bone Tumor Age Common Location Periosteal chondroma
Children and Adults Proximal humerus, M>F 2:1 proximal and distal femur, and the phalanges of the hands and feet.
Moreover, it has been reported that Hoffa's disease may be associated with the development of ossifying chondroma
Collectively, the findings were consistent with a diagnosis of soft tissue chondroma
The most common intrinsic HFP disorders are Hoffa's disease, intracapsular chondroma
, nodular synovitis, shear injuries, posttraumatic and post surgery fibrosis.
Because chondrosarcoma lies on a continuum between benign chondroma
and malignant sarcoma, making a histologic diagnosis can be difficult.
3) Lacerte et al, (4) reported 2 cases of dural chondroma
(one from convexity and other from falx) and compared them with 45 cases of intracranial chondroma
reported in the literature in which the tumor had originated outside the skull base.
In recent years, many radiologists and clinicians have been working on the development of IFP into metaplasia and chondroma
due to these mesenchymal cells.
