Reviewer's report:  
 
In my opinion, this paper is about an interesting case report.  
Its topic is a very current.  
The article is well organized. I have only some minor, but at the same time, important points to 
underline in order to obtain a better paper.  
 
My advices are the following:  
- To add more references and particularly to insert them in all sections of the text (ie, 
background);  
- To check all the abbreviations used in the text and to add them in the "list of abbreviations" 
(ie, SBA, EMR);  
- To check line 79, where ther is an ortographic mistake ("Biopsy" with capital letter).
