PEER REVIEWER COMMENTS: 
GENERAL COMMENTS: The report is well written and describes an interesting case of hepatic
histoplasmosis occured in a patient with long term methotrexate and infliximab. Entire description
reveals the difficulty of the diagnosis workup.
REQUESTED REVISIONS: 
The case presentation is a little bit too extended (2 pages of case description until the final diagnosis).
The authors should reduce this part. 
However, the complication relateded to the condition (pleural effusion) were little described. What was
the nature of pleural effusion (exudate vs. transudate, protein levels, citology report). 
Without an high level of suspicion, most of the time (like in this case) the diagnosis is made on liver
biopsy. Therefore, the authors should discuss the importance of liver biopsy and, what are the typical
histology features of histoplasmis. 
In the discussion part (page 9, first paragraph), rather than listing the published case reports (that is also
presented in the Table), an integrative disscussion would be preferred (conclude the common feature of
the cases).
