Abstract

Pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by the abnormal accumulation of alveolar surfactant protein in alveolar spaces. We report herein a rare case of myelodysplastic syndrome (MDS-RAEB) complicated by severe PAP, and successful allogeneic bone marrow transplantation (BMT) for both disorders. An unrelated BMT was planned for a 48-year-old male with advanced MDS-RAEB. Just before the initiation of the conditioning regimen for unrelated BMT in March 2007, he developed dyspnea. A diagnosis of PAP was made based on findings of chest X-ray, CT scanning, and the fluid obtained by bronchoalveolar lavage. To improve his dyspnea and improve BMT safety, whole lung lavage (WLL) was performed twice, with the partial improvement of PAP. Unrelated allogeneic BMT was performed in September 2007. We had to perform a third WLL because of the worsening of PAP on day 26 after BMT. Despite many infectious complications after BMT, GVHD was relatively mild. PAP had almost disappeared 6 months after BMT. He was well with favorable hematopoiesis 20 months after the BMT without any specific treatment. There has been no report of an MDS patient with PAP in whom 3 WLL procedures were performed before and after allogeneic BMT.
