Two cases of lipoma developed in the region of mandibular angle were studied, and the following results were obtained.1. Both of the patients were males in their forties.2. Both of the lipomas were subcutaneous tumors located at the mandibular angle. They were soft tumors with a clear boundary.3. Ultrasonic examination of the lipomas showed a heterogeneous solid pattern with an unclear boundary.4. The isolated lipomas were lobulated yellowish tumors covered with a thin capsule.5. Histopathologically, the lipomas consisted of mature fat tissues, and they had a lobulated structure due to the boundaries caused by blood vessels and peripheral connective tissue.
