Aggressive or conventional osteoblastoma: a diagnostic dilemma

Abstract

Osteoblastomas are primary benign bone forming tumours which are not common in the cranio - facial region. Here, we present a case of recurrent osteoblastoma in a 25 year old male which involved the maxilla and extended into the adjacent maxillary sinus and nasal cavity. The involvement of maxilla with destruction of paranasal air sinuses is quite rare. We also discuss the histological differential diagnosis, along with clinical features helped to arrive at the correct diagnosis.
