Malignant osteoblastoma of the skull

Abstract

A bone tumour of intermediate grade malignancy in the skull is described. These tumours are extremely rare and share several histological features with the benign osteoblastomas and low grade osteosarcomas. They may be associated with local invasion and pulmonary metastases. Treatment of this tumour in the skull poses several problems in view of its proximity to the cerebral cortex.
