Reviewer's report:  
Author Described a case of IgG4 related inflammatory tumor in liver,  
1. The entity is now not very rare or surprising. It is a well established fact that IgG4 related 
disease can present as mass  lesion and these are antibiotic and steroid responsive.  
2. Second point author highlight that these entity mimic with malignancy and histopathological 
diagnosis is required, that is also very well established fact.  
3. Authors mentioned that patient underw ent pancreatico -duodenectomy for Hilar 
cholangiocarcinoma, this is beyond the understanding, since authors have not mentioned 
whether there was partial hepatectomy done or not.  
4. And it is surprising that authors have not mentioned the Pathological and cl inical staging of 
previous tumor.  
5. If patient was having Hilar Cholangiocarcinoma, then how author's will describe the good 
tumor reponse and patient's excellent survival.
