Abstract

Introduction: Lipoma is the most common benign tumor which composed 25-50% of soft tissue tumors.This tumor can undergo a variety of changes, one of which is ossification. Osteolipoma is a rare benign tumor which is especially uncommon in the oral cavity.
Case report: This is a case report of an osteolipoma of the oral cavity in a 68-year-old male who was referred for a painless mass on the mandibular alveolar mucosa since about four years ago. Histopathologically, the lesion was composed of trabeculae of bone and mature adipose tissue confirming to be an osteolipoma.The patient recovered after resection.
Discussion: Osteolipoma can originate from osseous  metaplasia  within a long-standing lipoma following permanent stress,repeated  microtrauma and prolonged ischaemia.Osteolipoma  has the same prognosis as simple  lipoma.The treatment of choice is excision. There have been no reports of recurrence.
