Lipoma: some people may have abnormal fat metabolism due to hereditary reasons, in which case they may suffer from lipoma, in which case the patient will have the symptom of sarcoma in several parts of the body. 2. Sebaceous gland duct blockage: when the sebaceous gland secretion is abnormal, the sebum will accumulate in the duct, which can not be discharged from the body in time, leading to sebaceous cyst disease. At this time, patients will also have the symptom of sarcoma on the body, and at the same time, patients also have the symptom of pain and redness and swelling at the tumor site. 3.
