Background: Stenotrophomonas maltophilia-induced pulmonary haemorrhage is considered a fatal infection among haematological patients. The outcome can be explained by the patients' immunity status and late diagnosis and treatment.
Case Presentation: We present the rare case of successful outcome in a 61-year-old female who developed alveolar haemorrhage and acute respiratory distress syndrome 8 days after a chemotherapy session for her acute lymphoblastic leukaemia, in the context of secondary bone marrow aplasia.
