Abstract

Pseudomonas aeruginosa is a motile, aerobic, gram-negative rod that has become a leading infectious agent among patients who were hospitalized and immunocompromised. We report a case of preseptal periorbital cellulitis due to pseudomonas with focal skin necrosis (ecthyma gangrenosum) in a patient with severe immunocompromise. Ecthyma gangrenosum is known to be associated with sepsis and death but is rarely reported as a complication of preseptal cellulitis.
