Pseudomonas aeruginosa skin infections in two immunocompetent children under one year of age

Abstract

We describe two cases of Pseudomonas aeruginosa skin infections in immunocompetent children, both following viral infections. The first one presented with fever and erythematous cutaneous nodules that enlarged and developed into abscesses. Biopsy of a nodule revealed panniculitis with P. aeruginosa. The second case presented with deep necrotic inguinal ulcers consistent with  ecthyma gangrenosum. These two presentations are rare conditions in healthy infants without bacteremia. This report aims to answer questions such as the source of the contamination, the usefulness of the antibiotics or surgical drainage in the treatment, and the association of leukopenia with infection or immunodeficiency.
