Title: 
Signet-ring cell carcinoma of the duodenal bulb
presenting with gastrointestinal hemorrhage: a case report and literature review
Version:

Reviewer's report:
In their report, Ye et al. describe a case of signet-ring cell carcinoma of
duodenum presenting as a GI hemorrhage. Their case is generally well presented
and interesting, offering insight into an extremely rare diagnosis. My only
suggestion is for the authors to extensively proofread their manuscript for
grammar and sense, as there are several errors throughout. I advise that they
have this work edited by either a professional English language editing service,
or a native English speaker. Following language corrections, I see no reason why
this report would not be suitable for publication.
