Answer

With an excisional biopsy, the entire lesion is removed surgically. Grossly, many sarcomas appear to be well demarcated. Microscopically, however, the demarcation usually is seen to exist along a pseudocapsule with foci of infiltrating tumor. Removal of the tumor along this apparent plane may leave gross or microscopic sarcoma behind. Excisional biopsy may be safely performed for small, superficial tumors (less than about 5 cm in diameter) or for those known to be benign. [27]
