Liposarcoma

　　The etiology of liposarcoma is not yet clear. For malignant tumors, it is usually caused by the activation of oncogenes, so it may be related to environmental factors, genetic factors, and dietary factors.

　　Liposarcoma generally has no complications, easy to relapse after resection, poorly differentiated ones are prone to metastasis, mostly to the lungs and liver. Most of them only locally invasive growth, easy to relapse after resection, poorly differentiated ones are prone to metastasis, mostly to the lungs and liver.

　　Liposarcoma is more common in men, often occurring in middle-aged and elderly people (30-80 years old, average 50 years old), mostly in the lower limbs, especially the thigh, also seen in the buttocks, upper limbs, neck, and trunk. The skin lesions are nodular or lobular, often large, with a diameter of 2-20 cm (average 10 cm), soft, some with cystic sensation, with clear boundaries, generally painless. Most of them only locally invasive growth, easy to relapse after resection, poorly differentiated ones are prone to metastasis, mostly to the lungs and liver.

　　There is currently no effective preventive measure for liposarcoma. Early detection and early diagnosis are the key to the prevention and treatment of the disease. Early detection, early diagnosis, and early treatment are of great significance for indirect prevention of the disease. Pay attention to a good attitude and healthy factors, avoid bad living habits, such as drinking frequently, staying up late, etc.

　　Liposarcoma is generally found in deep soft tissue and then extends to subcutaneous tissue through histopathological examination, and a few occur in subcutaneous tissue. It is rare to originate from the dermis, and it can occur in locations where there are no mature adipose cell tissues. According to the type of tumor cells, the tumor can be divided into well-differentiated type, mucinous type, round cell type, and pleomorphic liposarcoma.

　　Liposarcoma patients should mainly eat light food, pay attention to dietary regularity. Patients should also pay attention to eating foods containing sufficient starch and fiber, avoiding excessive intake of cholesterol. Maintain a balanced diet and maintain an ideal weight. Avoid eating too much sugar.

　　Small tumors of liposarcoma should be excised and sent for biopsy. For large tumors, they can be excised and sent for biopsy under the condition of blocking blood supply, and the operation can be completed together. For liposarcomas with rapid development and high estimated malignancy, the surrounding muscle tissue (including the origin and insertion) should be excised at the same time.
