      The actual surgery was excellent and I was very pleased at the healing process. I was expecting to have definitive pathology results and the doctor said the report was insufficient and that my case was unusual. He said I needed to follow up with my referring dermatologist, which left me frustrated. It has been 5 months since the problem started.

      I loved all the teaching in response to my questions. Learned a lot about my diagnosis, my condition, good and full of explanations of the surgery in response to my questions
