ing from the epiphyseal region of long bones. A review of the literature reveals that the most common locations for this tumor are the knee and proximal humerus (14). The most common age group is the second decade of life. Cases of chondroblastoma of the rib in the literature are few and far between (5-7); the patients in these reports were older than typical patients with epiphyseal chondrobla...

in the axial skeleton. Fibroma, aneurysmal bone cyst, chondroblastoma and fibrous dysplasia must be evaluated in the radiographic differential diagnosis of chondromyxoid fibroma. Being an eccentric metaphyseal location, showing sharp, sclerotic, scalloped margins and matrix calcification are its major radiographic features. In pathological evaluation, the tumour shows a distinctly lobulated pat...

The first aim was to differentiate chronic infection from neoplastic bone lesions. Acid fast bacilli culture excluded a tuberculous infection. Confirmation was achieved by performing an open biopsy and histopathological examination of the specimen. The final diagnosis of chondroblastoma was confirmed in view of there being a marked cellular chondroid component rather than fibrous component in t...

Introduction: Osteomas are asymptomatic and rare slow growing bony tumors in temporal bone, and should be taken into account in differential diagnosis of the osteolytic solitary skull lesions. Sometimes is associated with pain and functional loss. Only a few cases have been reported.   Case Report: We describe a case of an osteoid osteoma of the temporal bone (mastoid) in a 31-year-old woman pr...

The case of a 51-year-old man with a large temporal mass is presented. The mass eroded the floor of the middle fossa medially to the sphenoid sinus. A combined approach with neurosurgery and otolaryngology was performed to achieve maximal resection of the mass. Pathology was typical for chondroblastoma: a rare, benign but locally invasive chondroid tumor. Genetic testing revealed a translocatio...

Chondrosarcomas are the second most common bone sarcomas, accounting for less than 0.5% of all cancers. The treatment plan can be improved by analyzing clinical characteristics and patterns. rarity slow-growing nature this tumour often lead to prolonged symptoms also initial misdiagnosis with avascular necrosis femur, benign lesions like chondroblastoma. reports patient suggested femur head. Hi...

Extraosseous chondroblastoma had been reported in different parts of the body but not intracranially. We report a case of a pathologically proven intracranial extraosseous chondroblastoma of the right cavernous sinus in an 18-year-old woman with CT, MR, and conventional angiographic features simulating meningioma.

Patient. We describe a case of chondroblastoma of the os calcis which metastasized to the tibia, soft tissues and lung. A complete response of the lung lesions was noted with chemotherapy.Discussion. Review of the published literature shows that metastatic chondroblastoma only arises following local recurrence of the tumour.

The first aim was to differentiate chronic infection from neoplastic bone lesions. Acid fast bacilli culture excluded a tuberculous infection. Confirmation was achieved by performing an open biopsy and histopathological examination of the specimen. The final diagnosis of chondroblastoma was confirmed in view of there being a marked cellular chondroid component rather than fibrous component in t...
