Aggressive osteoblastoma (AO) is a rare benign neoplasm of the bone commonly occurring in the vertebrae and long bones andrarely in the jaw bones[1]. It is locally invasive with high chances of recurrence compared to conventional osteoblastoma.Histologically AO is characterised by the presence of epitheloid osteoblasts.We present a case of a 48year old female with AO of the maxilla with four recurrences.The tumour could only be rightly diagnosed in the second recurrence. With other bone lesions having similar clinical, radiological and histopathological features,this lesion poses to be a diagnostic challenge to both the clinician and the pathologist.
