BACKGROUND All drugs have the potential to cause drug-induced lung injury both during and after drug administration.Acetaminophen has been reported to cause druginduced lung injury,although this is extremely rare.Herein,we present an extremely rare case of acetaminophen-induced pneumonia.CASE SUMMARY A healthy 35-year-old Japanese woman visited a neighborhood clinic with complaints of fever and malaise following a tick bite.Her treatment included1,500 mg acetaminophen(Caronal^(?)) and subsequently minocycline(200 mg) and acetaminophen(2,000 mg;Caronal^(?)) daily when her condition did not improve;the patient was eventually hospitalized.The patient’s chest computed tomography(CT) revealed consolidation and ground-glass opacities in the right middle and lower lobes.Minocycline was shifted to sulbactam/ampicillin.However,her fever did not improve during follow-up,and her chest CT revealed extensive ground-glass opacities in the right middle and lower lobes and thick infiltrative shadows in the bilateral basal areas.Drug-induced lung injury was suspected;hence,acetaminophen was discontinued.The fever resolved immediately,and inflammatory response and respiratory imaging findings improved.A drug-induced lymphocyte stimulation test was performed against acetaminophen(Caronal^(?)),and significant proliferation of lymphocytes was noted only for acetaminophen(stimulation index,2.1).CONCLUSION Even common drugs such as over-the-counter drugs can cause drug-induced lung damage.
