How do I explain this procedure?
“I need to take a sample of your skin lesion to find out what it is. The method is called a shave/saucerisation biopsy. I will use a small blade to shave off the upper layer of the skin. It will not need stitches.”
What can my patient expect?
“I will give you an injection so that you will not feel me taking the sample. You may feel tugging and working in the area, but it will not be painful. The laboratory test may take a few days
or longer

, and we will then contact you about your diagnosis.”
What is my patient’s role?
