Two cases of lipoma in the oral cavity

Lipoma, a benign lesion composed largely of fat tissue, is one of the most common of all neoplasms and is rarely seen in the oral cavity. We experienced two cases of lipoma in the oral cavity.Case 1: The patient, a fifty-four year old woman, noticed swelling on her left buccal mucosa. The tumor arose from the submucosal region of the mucobuccal junction which corresponded to the left mandibular molars. The tumor was excised under local anesthesia. From histological examination, the diagnosis of lipoma was based on the fact that the circumscribed mass of mature fat cells was observed below thin fibrous connective tissues.Case 2: The patient, a seventy-five year old woman showed a swelling on her right maxilla tuberosity. The tumor was excised under local anesthesia. From histological examination, the diagnosis of fibrolipoma was made based on the fact the circumscribed mass of mature fat cells was observed below rich fibrous connective tissues.Postoperative courses of those patients were not eventful.
