Autopsy of Drug-induced Lung Injury with Atypical Diffuse Alveolar Disorder due to Amiodarone.

Amiodarone, a prominent antiarrhythmic drug, may cause lung injury. We herein report the case of an 87-year-old man who had been taking amiodarone for 5 years and was subsequently referred due to respiratory failure. Chest computed tomography revealed multiple consolidations with air bronchograms in both lungs.

Refractory Eosinophilic Granulomatosis with Polyangiitis Complicated with IgG4-related Disease Showing Different Treatment Responses for Each Organ.

We herein report a 75-year-old woman who presented with dyspnea and purpura. She was diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) based on axonal damage observed in the left tibial nerve and skin and lung pathologies.
