Principles of Surgical Treatment of RSTS

Sarcomas are located on the superficial aspect of the skin or deep fascia, which is largely uninvolved. It is a tumor nodule type with the maximum diameter less than 5 cm (equivalent to stages I and IIA of the UICC staging), and its wound can be closed without repair or via simple method after re-resection. It is a true surface malignancy, including sarcomas, skin malignancies, and other types of malignancies.
