Reviewer ’s report  
 
Title: A rare case of Epstein –Barr virus -positive mucocutaneo us ulcer that developed into an 
intestinal obstruction  
 
Version: 0 Date: 19 May 2019  
 
Reviewer: Hongbo Wei  
 
Reviewer's report:  
 
1.The authors reported a rare case of EBV -MCU manifested as a big mass in the transverse colon 
that finally developed into intestinal obstruction. This case added novel informatio n to the field 
that EBV -EBU can cause ileus even in its period of regression, and needed to be surgically 
resected.  
 
2.I doubt the decision not to perform a laparotomy when first -time CT scan and colonoscopy 
discovered a tumorous lesion in the transverse co lon which had already caused luminal stenosis. 
I think the authors should discuss this in the paper.  
 
3.The manuscript requires a thorough revision of the grammar and structure by a native English 
speaker.  
 
4.Laboratory finding did not need to be repeated in  the text and in the table.  
 
5.I suggest the authors to combine all the three CT images into a big figure arranged in 
chronological order.  
 
6.Overall, I would like to afford the authors a chance for a major revision.
