An unequivocal diagnosis of sarcoidosis cannot be made histologically
Appropriate terminology for a report could be:
"Noncaseating granulomas, see comment"
The comment may state that the findings are consistent with sarcoidosis, but that infection, hypersensitivity pneumonitis, reaction to inhaled minerals and metals (beryllium, aluminum, talc) or drugs must be ruled out
Results of stains and cultures should be given, with the warning that they are not 100% sensitive
