Chondroblastoma is a rare, benign bone tumor that represents 1-2% of all primary bone tumors. Denosumab, a monoclonal antibody, has been demonstrated to inhibit the growth of giant cell tumors. We report a case of recurrent chondroblastoma of the squamous temporal bone that is currently suppressed with denosumab.

Chondroblastoma is a benign epiphyseal chondromatous lesion typically seen as small, well-defined, eccentric with thin rim of surrounding bone sclerosis. Soft tissue extension, metaphyseal involvement, periosteal reaction, cortex breach though not pathognomonic, are reported in literature. We present case report patient chondroblastoma showing atypical radiological presentation exophytic mass o...

Chondroblastoma is a benign cartilaginous neoplasm usually arising in the epiphyses of long bones in young subjects. The histogenesis of chondroblastomas is controversial, although cartilage germ cells or epiphyseal cartilage cells are presumed to be the cell of origin. The most common anatomical site involved by chondroblastoma is the proximal humerus followed by the distal femur, proximal fem...

Background: Chondroblastoma of the spine is a very rare condition. To the best of our knowledge, fewer than 30 cases have been reported in the world literature. Material and methods: The authors describe here a rare spinal localization with an uncommon evolution and make a review of the cases of spinal chondroblastoma reported in the literature. Results: We report the case of a patient with chr...

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...

Chondroblastoma is a rare, benign tumor of bone, accounting for about 1% of all bone tumor cases. It tends to affect the epiphyseal ends of long bones, most often in males during the first and second decades of life. It has well-characterized radiographic and histologic features but despite its histologically benign appearance a few cases of metastases have been reported. Local recurrences afte...

Patella is a relative uncommon site for chondroblastoma. Most of cases of chondroblastoma in patella reported in literature are treated with patellectomy. We treated a large chondroblastic lesion in patella of an 18year-old male with curettage, burring & bone graft and the result was satisfactory after 3 years post operation.

Aneurysmal bone cyst (ABC) is a rare benign cystic lesion of the bone that composes 1-2% of the entire bone tumors. Some are idiopathic, and some occur secondary to other tumors such as giant cell tumor and chondroblastoma. In this article, we report the clinical, radiographic, and histological findings of a secondary ABC following chondroblastoma of the patella with a review of the literature.

Chondroblastoma is a rare tumor which constitutes 1 % of the primary bone tumors . It most frequently arises from the epiphysis of the long bone. Involvement of the temporal bone is rare. Complete removal is a challenge due to anatomical complexity of the involved area including the middle ear and skull base. We encountered a case of temporal bone chondroblastoma that was safely removed by usin...

This is a case report of a 24-year-old man who presented with increased pain and firm swelling of the right foot after a minor twisting injury. Radiography, computed tomography (CT) and magnetic resonance imaging (MRI) findings showed ancillary information that was helpful for surgical treatment. The final diagnosis was confirmed as chondroblastoma of the navicular bone based on the pathology r...
