Lipomas are a common type of benign tumor that we see clinically. Most cases are benign, and malignant transformation is very rare. Lipomas consist of normal, fatty-like tissue and primarily occur on the limbs and trunk. They have clear boundaries, are lobulated in appearance, soft in texture, and may feel like a false cyst. They are painless and grow slowly. Some can grow very large, and deep-seated ones may undergo malignant transformation and should be treated surgically in a timely manner. In terms of treatment for lipomas, medication is ineffective. Small lipomas can be monitored periodically. If a lipoma is large, affects daily life or aesthetics, or is a deep-seated lipoma that might become malignant, surgical treatment is required.
