Giant Cell tumors (GCT) are benign tumors with potential for aggressive behavior and capacity to metastasize. Although rarely lethal, benign bone tumors may be associated with a substantial disturbance of the local bony architecture that can be particularly troublesome in peri-articular locations. Its histogenesis remains unclear. It is characterized by a proliferation of mononuclear stromal ...

Temporal bone chondroblastoma is an extremely rare benign bone tumor. We encountered two cases showing similar imaging findings on computed tomography (CT), magnetic resonance imaging (MRI), and dual-time-point 18F-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/CT. In both cases, CT images revealed temporal bone defects and sclerotic changes around the tumor. Most parts of the ...

central cementifying fibroma is a bony tumor, which is believed to be derived from the cells of the periodontal ligament. central cemento‑ossifying fibroma behaves like, a benign bone neoplasm. this bone tumor consists of highly cellular, fibrous tissue that contains varying amounts of calcified tissue resembling bone, cementum, or both. central cemento‑ossifying fibromas of the mandible are co...

Implantation metastasis occurs when tumor seeds into a wound or tissue by a significant amount of viable tumor cells. Here we describe the case of a 30-year-old man suffering from pain and swelling of the foot, which was misdiagnosed as a bone cyst. Surgery was performed involving curettage followed by bone grafting. After surgical pathology, the exact diagnosis was revealed as the synovial sar...

Osteosarcoma (OS) is the eighth common cancer of childhood and its incidence is 4 cases in one million in children younger than 14. Facial OS incidence is estimated between 8 and 10% of OS cases. The main etiology of OS is unknown, but various predisposing factors are proposed such as radiation, radiotherapy, some benign bone diseases like Paget’s disease or fibrous dysplasia. There is a 5-year...

background : meningiomas are common benign tumors of the central nervous system. patients with meningiomas achieve postoperative optimal functional recovery, but there is a probability of tumor recurrence months or years after surgical resection. this study aims to evaluate the prevalence of recurrent meningioma and the correlation between tumor recurrence and certain factors. materials and met...

Chondromyxoid fibroma (CMF) is a rare benign cartilaginous tumor with a predilection for the bones of lower extremities and about one fourth of the tumors involve the foot.Radiologically, an eccentric lytic lesion with well defined margins is seen in the metaphysis of the bone. We hereby, report an 18 yr old young male who presented to Orthopedic Outpatient Department, JN Medical College, Aliga...
