Lipomas do not necessarily require surgical treatment. They can occur in various parts of the body and are usually characterized by good mobility, a complete capsule, no tenderness, a firm texture, and mostly clear boundaries. They often present no clinical symptoms and are found incidentally. Diagnosis can be confirmed through ultrasonography. In most cases, patients only need follow-up observation. However, for lipomas in special locations, if they affect appearance or grow rapidly causing symptoms, surgical treatment may be considered. After a complete excision, pathological examination is necessary because a very small number of cases may turn out to be liposarcomas, which might require further treatment.
