Body surface tumors, i.e. swellings growing on the human body surface, can be benign or malignant. Benign tumors, such as lipoma, fibroma, neurofibroma, sebaceous cyst, etc., are mostly benign and do not have any effect on the body, so there is no need to worry. Malignant tumors on the body surface can be divided into malignant tumors derived from skin, i.e. skin cancer, and malignant tumors derived from mesenchymal tissue, i.e. sarcoma. The main manifestations include skin ulcers, nodules, lumps, papules, warty protrusions, pigmentation abnormalities, etc. Common skin cancers: basal cell carcinoma of the skin, squamous carcinoma of the skin, malignant melanoma of the skin, Paget’s disease, Bowen’s disease. Common sarcoma: fibrosarcoma, liposarcoma, rhabdomyosarcoma, malignant fibrous histiocytoma, malignant nerve sheath tumor, etc. Treatment of body surface malignant tumors The treatment method follows the principle of extended resection and radical treatment, and decides whether to choose integrated treatment such as radiotherapy and chemotherapy according to the nature and condition of the tumor. With the continuous progress of society, patients are more concerned about the effect of surgery on their appearance while paying attention to the effect of disease treatment. Other departments: Surgeons often adopt relatively conservative resection methods or even give up surgical treatment because they are concerned about the large trauma after tumor resection or the unrestorable exposure of blood vessels and bones after resection. Plastic surgery: Because of its technical characteristics, it can apply tissue transplantation technology to the repair of human body surface deformities and defects and the reconstruction of body surface organs. Compared with other departments, the advantages of plastic surgery are: 1. Expanded resection of malignant tumors can remove the cancerous tissues to the maximum extent, thus avoiding the spread of tumor cells and recurrence. 2.While designing the surgical plan, consider repairing and reconstructing the function of tissues and organs; at the same time, make a better soft tissue coverage in the operation area, so as to provide good conditions for later radiotherapy and chemotherapy, etc. 3. Adopting plastic surgery technique for suturing can minimize and hide the postoperative scar, and patients have high postoperative satisfaction. In conclusion, malignant tumor is important to be diagnosed and treated early. Through appropriate treatment of plastic surgery, the tumor lesions on the body surface can be completely removed and functional rehabilitation and appearance improvement can be achieved. Warm tips If some swellings appear on the body, there is no need to be alarmed, but the following points should be noted: 1. Frequent friction parts (such as palms of hands and feet, genitals, neckline, belt, etc.) are prone to malignant changes. 2, exposed parts (such as head, face and neck, etc.), often exposed to sunlight, prone to lesions. 3.Mole spots on other parts of the body need to be alerted if the area or volume suddenly increases; the color suddenly deepens and becomes black within a short period of time; sudden bleeding and rupture; itching, pain and other conscious symptoms appear; and many new small black spots appear around them. If you are unable to judge, it is recommended to consult a professional doctor at a regular hospital in time to avoid delaying the disease.
