Pseudomonas aeruginosa Infections of Intact Skin

Abstract

Pseudomonas aeruginosa infections of healthy skin are uncommon. We report four cases of P. aeruginosa infections of intact skin. These cases illustrate the clinical spectrum of these cutaneous infections: localized, mild epidermal infections (the green nail syndrome and webbed space infections), moderately serious infections (cutaneous folliculitis and otitis externa), and, in immunocompromised patients, extremely serious infections (malignant otitis externa, perirectal infection, and ecthyma gangrenosum).
