Yea Chuck I had to have that MOHs thing a couple of years ago, had a melanoma on my cheek but they did a Slow MOHS job, no kidding. He the root system in melanoma is so tiny that they make a cut that fits the parameters generally, put in a dye for 24 hours then look at and go back for more if necessay. Fortunately my dermatologist elected not to do it himself and sent to a more specialized guy who got it all the first time. Just before he started to cut I threw him into a tizzy...my nose started itching and nobody told me not to scratch...he had to start the sterilizing routine all over, he wasn't happy...but it turned out well.
