Defect Repair After Resection of the Upper Limb Malignant Tumor

It is often required to use the plastic surgery techniques to repair the defect after resection of the body surface tumor in the upper limb; the relevant theories and measures can be referred to in Sect. 1.14 of Chap. 1. This chapter focuses on the discussion on the diagnosis and treatment of some malignant tumors in the hands, upper limbs, and soft tissues and the repair and reconstruction after tumor resection. The tumors in the hands, upper limbs, and soft tissues account for about 1% of all malignant tumors, a kind of malignant tumor with different histological and clinical characteristics. Because most tumors cause no pain or slight pain, the patients and the medical staff do not pay attention to them; therefore, there is a certain rate of missed diagnosis and misdiagnosis before surgery. The soft tissue malignant tumor is also known as soft tissue sarcoma and mostly occurs in the limbs, trunk, and retroperitoneal space; the most common soft tissue sarcomas are fibrosarcoma, synovial sarcoma, rhabdomyosarcoma, liposarcoma, leiomyosarcoma, and stromal sarcoma; the most common metastatic site is the lung [1].
