Granulomatous sarcoid-like thoracic and/or extrathoracic reaction

Histopathologically named sarcoid-like reaction. Drugs can elicit a perfect mimic of naturally-occurring intra- and/or extra-thoracic sarcoidosis. Both the timing of exposure to the drug and effect of discontinuation may corroborate whether the condition was drug-induced. Examination of the skin including tatoo edges and scars for evidence of granuloma can be rewarding (PMID 24239377).
