Thanks so much for your reply. It's great to hear that the inadequate margins were noted and you were treated successfully although with some delay. I can relate to your experience on several levels. My father was also referred to a local plastic surgeon rather than seeking care at nearby Memorial Sloan Kettering. I remember some question about margins. He did not survive beyond 5 years.
I noticed just today that the dermatology practice where my biopsy was performed includes two dermatologists labeled on the mast head as surgical dermatology while the dermatologist I was referred to for full excision is labelled general dermatolgy. Perhaps because they are trained in Mohs surgery and that is not required in my case...
