Multiple ecthyma gangrenosum in a healthy infant with community-acquired pseudomonas aeruginosa sepsis

We report the case of a previously healthy 8-month-old infant girl with Pseudomonas aeruginosa sepsis who presented to a pediatric emergency department with multiple ecthyma gangrenosum. Skin manifestations are uncommon in Pseudomonas infection. Ecthyma gangrenosum is a rare, distinct skin disorder associated with potentially fatal underlying Pseudomonas sepsis. Although typically occurring in immunocompromised or neutropenic patients, it can occasionally affect otherwise healthy children. This case demonstrates the critical importance of the pediatrician's identification of ecthyma gangrenosum to give directed antipseudomonal therapy.
