Osteoma is a benign bone-forming tumor that usually arises in the craniofacial bones and rarely in the long bones. Clavicular involvement is extremely rare. We report a 51-year-old woman with osteoma of the left clavicle. Radiograph of the left shoulder showed a well-defined lobulated blastic mass in the proximal and mid-portion of the left clavicle. Bone scintigraphy was performed 4 hours afte...

the primary carcinoma may secondarily invade bone tissue through direct extensions, blood circulation or lymphatic transportation particulary when it is arising from breast, prostate, kidney, thyroid and lung. metastatics tumors of bone are more common than primary tumor of bone. the most common tumor, which metastasizes into bone, is the breast adenocarcinoma. some metastatic tumors of bone in...

Introdouction: Fibrous dysplasia is a benign fibro-osseous lesion that affects craniofacial bones including the maxilla and mandible. In the most cases of fibrous dysplasia of facial bones, radiographic findings represent lucent or mixed radiolucent-radiopaque lesion with ill-defined borders and gradual blending of its border with adjacent bone . In this presentation, a patient suffering ...

Background: Plastic deformity is a fixed deformity of bones after application of force which is in contrast to elastic deformity, so it remains unchanged. It is a rare condition and is seen more commonly in upper extremity (forearm). Inability to recognize it causes limitation of motion and remaining of angular deformity. It occurs more commonly in children because of flexibility of their bones...

statement of problem: it is not known whether endochondral and intramembranous bones have distinct biological characteristics. octacalcium phosphate (ocp), a hydroxyapatite precursor, has been reported to stimulate bone formation after being implanted in parietal bone defects of rats. purpose: the present study was designed to investigate the response of endochondral and intramembranous bones t...
