Lipomas are the most common soft-tissue tumor. These slow-growing, benign fatty tumors form soft, lobulated masses enclosed by a thin, fibrous capsule. Lipomas are common benign mesenchymal tumors. They may develop in virtually all organs throughout the body. The anatomy depends on the tumor site. Subcutaneous lipomas are usually not fixed to the underlying fascia. The fibrous capsule must be removed to prevent recurrence. The cause of lipomas is not completely understood, but the tendency to develop them is inherited.
A minor injury may trigger the growth. Being overweight does not cause lipomas. No treatment is usually necessary for a lipoma. However, if the lipoma bothers, treatments includes, Surgical removal, Steroid injections, Liposuction. This study evaluated the clinical and histopathologic aspects of 41 cases of oral lipomas diagnosed in a Brazilian population. All records from patients diagnosed with oral lipoma between 1970 and 2008 were reviewed. Histological sections were evaluated by light microscopy.
