Gigantic epulis with pillar-shaped bone formation: Report of case

Abstract

A case of gigantic epulis of the mandible with pillar-shaped bone formation is reported. The patient was a 37-years-old man. He complained of a slowly growing, painless, tumor protruding from the right molar region of the mandible to the maxilla. The color of the lesion was normal. On palpation, the lesion was elastic hard with an irregular surface, but had a bony hard base. There was bone resorption of the maxilla at regions in direct contact with the tumorous mass. Radiographically, pillar-shaped bone formation was observed in the lesion. The clinical diagnosis was epulis. The epulis was excised with the patient under NLA anesthesia. The excised specimen measured 30×45×40mm. The bone in the lesion was shaped like a pillar and adhered to the mandible. The histopathologic diagnosis was epulis osteoplastica.
