Abstract
Osteoblastoma is a rare tumor which forma osteoid and bone with highly vascular
stroma, account for less than 1 percent of all bone tumors. The lesion had been thought
to be controlled with curettage and local excision. In recent years, cases of locally
aggressive but not metastasizing osteoblastomas have been described as aggressive
osteoblastoma or malignant osteoblastoma, separated from the innocuous behavior of
usual osteoblastoma. It represents the histologic characteristics of the presence of
epithelioid osteoblasts, trabecular rather than lace, like osteoid, low mitotic rate with no
atypical form with prominent giant cells of osteoclastic type.
The differential diagnosis between aggressive osteoblastoma and osteogenic sarcoma is
extremely difficult, but its peculiar histologic pattern and its different clinical and
radiologic features and better prognosis are helpful.
We report here a case of aggressive osteoblastoma of 17 years old female Patient
with 2 yearn and 5 months follow, up period and review the literature.
