Lipomas, composed of mature fat cells, are benign tumors which grow under the skin and typically appear as round or oval lumps with no change to the skin color and texture of the area. While they may occur anywhere, they typically appear on the neck, trunk, abdomen, and forearms. Removal is usually recommended if it is causing pain, pressure, irritation, or is growing. Patients also may choose to have it removed for cosmetic reasons.
Often, if the lipoma appears large and diffuse, liposuction can be performed and results in less scarring. When liposuction of the lipoma is not an option, a surgical excision is recommended.
