SURGERYSurgery is undertaken to clear lesions which cannot be managed by simpler means. As illustrated a margin of healthy tissue is re-moved around the lesion so that the lab can examine it under the microscope to determine the characteristics and complete excision. You will note that a simple excision illustrated is aligned into the skin folds for best scar results and takes the shape of an
