Lipoma is a common disease in clinical practice, and it is generally not very serious, so there is no need for excessive worry. A lipoma is a tumor-like mass of normal tissue, commonly found on the trunk and limbs of the body. It has a clear boundary and is lobulated, soft, and may feel like a false cyst, painless, and grows slowly. Some can be quite large. Deep lipomas that might turn malignant should be removed promptly. Generally speaking, lipomas only require surgical treatment if there is suspicion of malignancy, if the tumor is large enough to affect daily life or aesthetics, or if malignancy is suspected.
