Reviewer's report:  
 
I have read with great interest the manuscript entitled, "A rare end oscopic appearance of 
granulomatosis with polyangiitis involving the intestine: case report" by Pan and co -workers.  
This is a unique case report.  The major problem with this manuscript is a poor English writing.  
This manuscript has great potential if th e authors can take their time and pay careful attention to 
details and rewrite the entire manuscript.
