Ecthyma gangrenosum describes a cutaneous infection with Pseudomonas aeruginosa that is manifested by necrotic plaques with an eschar. The infection usually occurs in immunosuppressed patients. Three to six percent of Pseudomonas septicemia is complicated by ecthyma gangrenosum (1). The term ecthyma gangrenosum was given by Hitschmann and Kreibich in 1897 in Germany to describe necrotic cutaneous plaques due to cutaneous involvement in disseminated Pseudomonas infection. However, ecthyma gangrenosum is now known to be a morphologic pattern of cutaneous infection caused by a wide variety of organisms.
