title: Nonpseudomonal ecthyma gangrenosum.
abstract: Ecthyma gangrenosum is a cutaneous infection associated most commonly with pseudomonal sepsis in the patient who is immunocompromised. We describe an 8-month-old girl with acute myelocytic leukemia who developed perineal ecthyma gangrenosum caused by Citrobacter freundii, a gram-negative pathogen that has been rarely associated with cutaneous disease. We also review the literature to categorize the range of pseudomonal and nonpseudomonal pathogens associated with ecthyma gangrenosum.
