Neumonía hemorrágica por Stenotrophomonas maltophilia. Presentación de caso y revisión de la literatura

Abstract

Hemorrhagic pneumonia caused by Stenotrophomonas maltophilia (SM) is a rare disorder, but its importance lies in the severity, rapid progression, and high mortality of this presentation, specially in immunocompromised patients, being severe neutropenia one of the main risk factors for this kind of pneumonia. Specifically, severity and rapid progression are the main characteristics that should make us suspect this disorder when a patient presents some of the risk factors; we should also start empirical antibiotic treatment if there is high suspicion. Here we display a case where a 56 year-old woman, diagnosed of multiple myeloma, and receiving chemotherapy, develops hemorrhagic pneumonia caused by SM, rapidly deteriorating in the first few hours.
