Laboratory results show peripheral eosinophilia and antibodies against neutrophil myeloperoxidase. What is the most likely diagnosis?? A: Allergic bronchopulmonary aspergellosis, B: Eosinophilic granulomatosis with polyangiitis Churg-Strauss syndrome, C: Cystic fibrosis, D: Paragoniums westermani infection, E: Pancoast tumor,  <response>: This is a clinical vignette describing a young adult male with symptoms of wheezing and rhinitis along with laboratory findings of eosinophilia and antibodies against myeloperoxidase. The key findings here are:- Young adult - Wheezing and rhinitis respiratory symptoms- Eosinophilia elevated eosinophils- Anti-myeloperoxidase antibodies Eosinophilia and anti-MPO antibodies point towards an eosinophilic inflammatory process. The respiratory symptoms make this most consistent with an eosinophilic lung disease. Of the choices given, eosinophilic granulomatosis with polyangiitis formerly known as Churg-Strauss syndrome is the most likely diagnosis. This vasculitic disorder classically presents with asthma, eosinophilia, and anti-MPO antibodies.The other choices are less likely based on the clinical vignette:- Allergic bronchopulmonary aspergillosis would not have anti-MPO antibodies- Cystic fibrosis would present earlier in life and not have eosinophilia - Paragonimus infection is unlikely with the geography given - Pancoast tumor would not explain respiratory symptoms or eosinophiliaB: Eosinophilic granulomatosis with polyangiitis Churg-Strauss syndrome
