In this paper, we describe our experience with a patient who had an intramuscular lipoma in the right side of the mental region. A man aged 81 years who had a history of a right-sided mental mass since 2002 was referred to our department by a dental clinic because of a gradual increase in lesion size. An elastic soft mass with a distinct boundary, measuring 18 × 15 mm, was palpable. In the oral cavity, it was also palpable within the premolar buccal mucosa. The color of the surface membrane was normal. Both T1 and T2-weighted magnetic resonance imaging showed high intensity. The mass was resected under local anesthesia for the diagnosis of a benign tumor, and the histopathological diagnosis was intramuscular lipoma. There have been no signs of recurrence during follow-up as of 1 year 8 months after surgery.
