Non Aggressive Mandibular Osteoblastoma- A Rare Maxillofacial Entity.

Benign osteoblastoma is a very rare, bone tumour occurring in the facial region. These lesions are most frequently seen in long bones. They are characterised by proliferation of compact or cancellous bone. The lesion is usually asymptomatic until it causes significant facial asymmetry or displacement of the teeth if present in the alveolar region. The clinical appearance of osteoblastoma is very similar to peripheral ossifying fibroma or any fibro-osseous lesion. The tumour is characterised by bone formation along with the presence of numerous osteoblasts. This case report describes the presence of a bony hard mass in the right side of mandible of a 27-year-old female patient with the chief complaint of a painless growth since past 10 years. The growth slowly increased in size displacing the teeth associated with it. The patient also complained of difficulty in speech and mastication.
