Fatty mass is a common benign clinical lesion, the reasons for the formation of fatty masses are mainly the following: First, the patient in the process of growth and development due to the intake of more adipose tissue, the body’s energy metabolism is in excess, at this time, a large amount of fat in the superficial skin accumulation can be formed fatty masses. The mass has clear boundaries, tougher texture and better mobility. For smaller fat masses, if there are no obvious symptoms of swelling and pain, close observation can be taken. Second, if the patient’s superficial tissue is severely traumatized, the local tissue in the process of repair can be accompanied by accumulation of adipose tissue to form a mass, if the adipose tissue in the incision overgrowth may form inflammatory granuloma. At this time, the patient’s incision will appear obvious redness, swelling, pain, and accompanied by purulent secretion, in this case, it is recommended that the patient perform surgical excision of overgrowth of granulation tissue, which can promote faster healing of the wound.
