Review for 10.1186/s12876-021-01849-8 (2021)

Reviewer’s report
Title: 
Small intestinal follicular lymphoma induced by methotrexate: A case
report
Version: 
1 
Date: 
20 May 2021
Reviewer's report:
Thank all authors' contributions to demonstrate such a rare but educational case.
However, I still have a small suggestion about the description in P6, L104-105. I
suggested add "During operation" before the sentence "An endoscope was...".
That will make reader more clear that the following description is relevant to
intraoperative endoscopic observation.
