Reviewer ’s report:  
 
The case report on a patient with pyoderma gangrenosum and auto immune hepatitis is well 
written and highlights an interesting association. Some minor changes have been suggested for 
author review.  
 
1. Case Presentation (page 4, line 26) do the authors mean anti nuclear antibody (ANA) and 
not anti neutrophillic antibod y) 
 
2. Figure 3 Please use arrow marks to point to the intradermal abscesses mentioned in the 
legend. Please expand the legend to explain more histopathologic details.  
 
3. There is some evidence to support that PG can be treated with Azathioprine, so the 
authors should add to discussion a comment on why this patient had to be switched to 
Cycosporine from Azathioprine.  
 
4. Please consider displaying all the images of the ulcer as one figure in a panel with the 
timelines marked in legend. For eg. Figure 1a at  presentation, 1b at 6months and so forth.
