I am sorry that after a month we have not yet had a poster that has had a similar situation to you that can help with your questions. While what your son has is not rare, it is not as common as the Squamous Cell Carcinomas that most of the visitors here have had. I am posting to you so that your original post will be brought back to the front of the current list again.
