Pulmonary hemorrhage and lung abscess caused by community-acquired pseudomonas aeruginosa in a previously healthy infant

Pseudomonas aeruginosa (P. aeruginosa) infections occur mostly in children immunocompromised by chronic glucocorticoids, immunosuppressive agents, or immune deficiency. When P. aeruginosa disease occurs in previously healthy children, it progresses rapidly, and most patients die of septic multiorgan failure. This case describes a 9-month-old previously healthy girl who presented with cough, fever, tachypnea, heart failure, pulmonary hemorrhage and shock. Blood and sputum cultures grew P. aeruginosa. She responded to culture-guided treatment and recovered by the 49th day of admission. We can learn more about P. aeruginosa in healthy children in the absence of ecthyma gangrenosum in this case. It would help diagnosis and treatment of this disease.
