The Rare Complication and Diagnostic Challenges of Pulmonary Eosinophilia in Graft versus Host Disease Patients after Hematopoietic Stem Cell Transplantation

Purpose Chronic graft versus host disease (cGvHD) is a common complication of hematopoietic stem cell transplantation (HSCT). Eosinophilic lung disease is a rare poorly understood complication in HSCT patients with cGvHD. These patients present similarly to those with Acute Eosinophilic Pneumonia (AEP). The purpose of this study is to better elucidate the presentation and potential treatment of this phenomenon.
