BACKGROUND Osteoblastoma is a rare and benign osteoid-producing primary bone tumor that affects mainly the long bones. 36% of these tumors are observed around the spine and the vast majority arises around the posterior. CASE PRESENTATION This report describes a case of C3-4 osteoblastoma occurring in a 5-year-and-8-month-old Han Chinese child. The pathophysiology of symptom development, evalu...

INTRODUCTION Osteoblastoma is a rare (incidence <1%) benign locally aggressive osteoblastic lesion of bone with rare malignant transformation. Benign osteoblastoma is the term used by Jaffe to denote an uncommon neoplasm of bone characterized by vascular osteoid and bone forming matrix rich in osteoblasts. CASE REPORT Here we report a case of osteoblastoma of talus in eighteen year old male p...

Osteoid osteoma and osteoblastoma are commonly seen benign osteogenic bone neoplasms. Both tumors are typically seen in the second decade of life, with a notable predilection in males. Histologically, these tumors resemble each other, with characteristically increased osteoid tissue formation surrounded by vascular fibrous stroma and perilesional sclerosis. However, osteoblastomas are larger th...

We describe a case of a 9-y-old girl who on (18)F-FDG PET imaging was found to have a highly metabolically active sacral tumor with an average standarized uptake value of 6.2. The tumor was proven to be osteoblastoma by pathologic examination. Osteoblastoma is a relatively rare benign primary bone tumor and occurs predominantly in patients younger than 20 y. The most common area of involvement ...

The clinical, radiological and pathological features of two cases of an osteogenic tumour with long survival are described. The tumours have the histological pattern of benign osteoblastoma with other more cellular and aggressive features suggestive of a low grade osteosarcoma. They are locally invasive but the absence of metastases indicates that separation from both entities is justified clin...

We reported the case of a 22 year-old boy who suffered a periosteal osteoblastoma of the distal fibula. The radiographic features of our case did not correlate with the majority of periosteal osteoblastomas of the long bones reported in the literature and were identical to a periosteal aneurysmal bone cyst. Periosteal osteoblastoma is a very rare tumor with a wide range of clinical and radiolog...

Osteoblastoma is a rare benign osteogenic bone neoplasm; it represents 1 to 3% of all bone tumors and usually seen in the second decade of life with a predilection in males. Classically it develops in the vertebral column. The skull is rarely involved and the orbital roof was reported to be less frequently involved. We report a new case of a benign osteoblastoma arising from the orbital roof wi...

Osteoblastoma is a benign neoplasia and is uncommon in the jaws. In some cases, this lesion presents extremely aggressive local characteristics and is termed aggressive osteoblastoma. Because the clinical, radiographic and histopathologic characteristics are similar to those of a variety of benign and malignant tumors, it poses a diagnostic dilemma. This report presents a case of an aggressive ...
