title: Beware the "red herring".
abstract: A young patient with relapsed diffuse large B-cell lymphoma presented with new onset respiratory symptoms and hypereosinophilia in the early stage post high-dose therapy/autologous stem cell rescue. Here, we present a step-wise practical approach to this unexpected laboratory finding for a not uncommon infective complication in the immunosuppressed patient.
