Benefit of therapeutic drug monitoring to disclose pharmacokinetic interaction between sunitinib and calcium channel blocker.

checkpoint inhibitor ipilimumab [3–7]. These cases cannot be diagnosed as sarcoidosis as these are immune reactions related to immune regulation after chemotherapy and/or immunotherapy. Additionally, granulomatous reactions are not limited to the lung. As suggested by Berthod et al. [7], these reactions are immunerelated adverse events. Perhaps, these reactions may be predictive for checkpoints inhibitors. At this point, appropriate terminology should be post-chemotherapy granulomatous reaction for cases treated with chemotherapy and post-immunotherapy granulomatous reaction in cases treated with immune checkpoint inhibitors or other immune therapies. We will see more similar cases in the near future due to the widespread use of checkpoint inhibitors. The correct terminology must be used by oncologists to avoid confusion for doctors dealing with sarcoidosis due to this chaotic terminology.
