Clinical manifestations Lipoma is quite common benign soft tissue lesion, which is formed by the excessive accumulation of normal fat cells. In recent years, the incidence of lipoma is gradually increasing, and subcutaneous lipoma is the most common one, which can occur in any part of the body, and is more common in the limbs and trunk, and is manifested as a nodule or lump in one or more superficial parts of the limbs and trunk, which can be single or multiple. There can also be localized compression symptoms and mild pain, which I call “idle pain”, that is, the pain is stronger when you are idle, but no feeling when you are busy. Zhang Yufeng, Department of General Surgery, First Affiliated Hospital of Zhengzhou University Causes The causes of lipoma may be related to the improvement of dietary conditions, and may also be related to the additives of food and the various types of excessive hormones contained therein, which have not yet been conclusively determined. Treatment The treatment of subcutaneous lipoma is surgery as the only clear and effective option, and there is still no effective drug treatment. Clinical reports of malignant transformation of lipomas are rare, therefore, lipomas in unimportant parts of the body or small in size, which do not have a great impact on life and work, can generally be left alone for the time being, while those with obvious symptoms of pressure or obvious obstruction to the appearance can be considered for surgical treatment.
