Reviewer's report:  
 
In this study, the authors described a rare case of Cronkhite -Canada syndrome. Manuscript is 
reasonably well written. There are some concerns regarding the manuscript.  
1. Why mesalazi ne was started? This case had involvement of stomach. What is the possible 
mechanism of pentasa in stomach?  Patient was on steroid too.  
 
1. Polyp size and numbers decreased aborally (Figure 2) (page 4, para 2, sentence 12 -13). 
Authors did not provided ima ges from small bowel. Usual pattern is extensive colonic 
polyposis followed by gastric mucosa hypertrophy ?  
 
2. In discussion, author could have described characteristic endoscopic features of CCS such as 
strawberry polyps, details of intervening mucosa e tc. Author could also have described 
endoscopic differential diagnosis of CCS. Author could also have described 
histopathological differential diagnosis of CCS.  
 
3. Please rewrite conclusion. Patients received steroid too. [Concluding Para - This case 
confir ms the successful application of mesalazine as initially published by Takakura[2] and 
additionally shows the possibility of a quick regression of polyposis, very likely leading to a 
reduced risk of colorectal carcinoma in this at -risk collective. ]
