Review for 10.1186/s12876-021-02050-7 (2021)

Reviewer’s report
Title: 
An unusual cause of ascites: Castleman disease
Version: 
1 
Date: 
26 Oct 2021
Reviewer's report:
As I wrote in the previous comment, since this case report is focused on ascites
in Castleman disease, the authors should add a description of what is known
about the causes of ascites formation in such disease. Furthermore, the authors
could provide a hypothesis on the reason why the ascitic fluid in this case is a
transudate.
