[Two cases of bacteremic pneumonia caused by Pseudomonas aeruginosa in solid-organ cancer patients].

Pseudomonas aeruginosa, the leading nosocomial pneumonia pathogen in immunocompromised patients, has Recently become typically presented as slowly progressive ventilator-associated pneumonia. We report two cases of bacteremic pneumonia due to Pseudomonas aeruginosa in non-neutropenic solid-organ cancer. Both subjects had sudden sepsis or septic shock but few respiratory symptoms. Chest radiography showed a diffuse unilateral decrease in permeability, becoming necrotizing pneumonia and lung abscess in 7-10 days. Conventional literature describe fulminant pseudomonas bacteremic pneumonia in non-neutropenic immunocompromised hosts as the initial presentation with septic shock and interstitial lung opacity, leading lung abscess.
