There are four different types of chondrosarcoma
The great majority of cases are primary or secondary chondrosarcoma. The mesenchymal and dedifferentiated types are extremely rare. [Read more...]

Osteogenic sarcoma is treated by radical excision and adjuvant chemotherapy. Before one proceeds for treatment, the clinical and radiographic diagnosis should always be confirmed by histologic examination of adequate tissue obtained by open biopsy.
Exuberant callus of a stress fracture, subacute osteomyelitis, active myositis ossificans, aneurysmal bone cyst, and eosinophilic granuloma are some of the benign conditions that can easily be mistaken for osteogenic sarcoma. Ewing’s sarcoma, fibrosarcoma, and metatastic carcinoma are some of the malignant lesions that must be considered in the differential diagnosis. [Read more...]

Osteogenic sarcoma presents a typical radiographic picture of destructive and osteoblastic changes.
The neoplasm usually begins eccentrically in the metaphyseal region of a long bone.
Bone destruction manifests itself as a loss of normal trabecular pattern and the appearance of irregular ill-defined, poorly marginated, ragged radiolucent defects.
New bone formation may be neoplastic or reactive and appears in the form of areas of increased radiopacity. [Read more...]

Osteogenic sarcoma develops from cells of the mesenchymal series, which form neoplastic osteoid and osseous tissue either directly or indirectly by rapid growth of development.
The classic osteogenic sarcoma develops in the interior of a bone. Juxta-cortical osteogenic sarcoma develops in relation to the periosteum and immediate parosteal connective tissue. It is less common, but has a much better prognosis. Endosteal osteo-sarcoma is a variant of parosteal osteosarcoma that arises within bone from the endosteum, a low-grade malignant tumor that grows slowly and metastasizes late. [Read more...]

It is pertinent that every case of acetabular fractures should be evaluated for nerve injuries so that such injuries are not missed. [Read more...]
