Unusually Large Peripheral Osteoma of the Mandible – A Rare Case Report

Osteoma is a benign tumor which is composed of mature compact or cancellous bone. Osteoma may be periosteal (arising from surface of the bone) or endosteal (develop in the medullary bone) or combination of both. Here, we present a case of unusually large osteoma present on the lingual surface of the mandible in a 40-year-old female patient. The lesion had grown slowly for 15 years and caused intra-oral swelling leading to difficulty in mastication, speech and tongue movements. Under general anesthesia, local complete surgical excision was performed.
