Submandibular Osteoma-Bony growth in the Lower Border of Body of Mandible: A Case Report

Osteoma is a benign slow growing tumour which commonly occurs in craniofacial bones. These tumoursoccur mainly due to proliferation of cancellous bone. It can be of peripheral, central or extra-skeletal type. In peripheral type which is described in this case report arises from the periosteom and is a very rare occurrence in the mandible. Osteomas are usually asymptomatic and can interfere with the aesthetics if they continue to grow to a larger size. These lesions are mostly discovered during routine clinical or in radiographs. Here we discuss a single large peripheral osteoma which arise from the right lower border of the mandibular body in a 50 yr old woman. This lesion caused a deformity of the facial region. Radiographic examination including IOPA, OPG and lateral oblique revealed a solitary radiopaque bony neoplasm. Incisional biopsy of the lesion confirmed the diagnosis to be an osteoma.
