Osteoblastoma is an uncommon benign bone-form ing tumor originally described in 1932 by Jaffe and Mayer [1]. it presents c linically with unusually severe pain that mayor may not respond to mild analges ics such as aspi rin . The radiographic appearance of osteoblastoma is often considerably varied, but , in most cases, it is an expanding lytic bone lesion that is usually well circu mscribed ev...

We report and discuss a combined anterior, anterolateral and posterior approach to the lower cervical spine. This was used for the radical resection of a recurrent osteoblastoma which involved the lateral mass, pedicle, and lamina of the sixth cervical vertebra.

Osteoblastoma occurring in the region of the hip is very rare, and vague symptoms with uncharacteristic radiographic features often lead to misdiagnosis. Because of radiographic and histological similarities, it must be carefully distinguished from osteoid osteoma, aneurysmal bone cyst, giant cell tumor, and osteosarcoma. Computed tomography is the preferred imaging modality as it is able to de...

An osteoblastoma is an uncommon benign but painful tumor, typically found on the axial skeleton or on long bones in the case of young patients. Some cases of humeral osteoblastomas have been described in literature but not in men older than 30. We report the case of a painless bone tumor on the humerus of a 52-year-old patient. The CT scan shows a 30 mm hypodense lacunar formation, surrounded b...

Osteoblastoma is a rare benign tumor that accounts for less than 1% of all bone tumors. About 10% of osteoblastomas are found in the skull bones and almost half of these cases involve the mandible, especially the posterior segments. This report describes the case of a 27-year-old female patient with a unilocular radiopaque expansive lesion in the left mandible, which had well-delimited margins ...

Benign osteoblastoma is an uncommon tumor in the skull and particularly rare in the temporal bone. This article presents the clinical, radiologic, and pathologic findings of the fifth case known to involve the temporal bone, and only th second case limited to the temporal bone itself. Subtotal removal was performed following embolization of the tumor. The patient currently has no evidence of di...

basal cell carcinoma (bcc) is currently the most common cutaneous cancer found in humans. although it generally shows a relatively benign course (bccl), some cases show aggressive behavior (bcc2). until recently, traditional histologic diagnostic criteria have failed to discriminate unequivocally between bcc 1 and bcc2. in this study we selected 50 cases of bcc and categorized them into two gro...
