Sarcoid-like granulomatosis (endo-/extrathoracic)
Last update 25/08/2022
Several drugs can cause a mimic of naturally-occurring endo- and/or extra-thoracic sarcoid-like reaction/sarcoidosis, or a flare of previously diagnosed sarcoidosis (particularly with the use of interferon, anti-TNF agents, or immune checkpoint inhibitors (PMID: 27504482). Both the timing of exposure to the drug and the effect of discontinuation are important to evaluate whether the condition is drug-related. Examination of the skin including scars and/or tatoo edges for evidence of granuloma can be rewarding (PMID 24239377). See also under PMID 33905479, VIIa, VIIe, and XL.
