Invasive pulmonary aspergillosis (IPA) is a well-recognized disease affecting immunocompromised individuals with prolonged neutropenia, inherited neutrophil disorders or T cell defects, with the risk depending on the patients’ underlying disease and the type and duration of immunosuppressive therapy [1]. Patients at the highest risk of invasive aspergillosis (IA) include those undergoing intensive chemotherapy for acute leukemia (AL) or recipients of allogeneic cell transplantation (alloHCT) who develop severe graft-versus-host disease, for whom antifungal prophylaxis is currently recommended [2, 3]. With changing treatment modalities, new risk groups continue to emerge, such as patients treated with ibrutinib [4, 5].
