Cutaneous Ulcerations Due To Infection with Stenotrophomonas Maltophilia

Aviva C Berkowitz, Caren Waintraub, Alexandra Flamm, Catherine Ding and Katy Burris

Stenotrophomonas maltophilia is an aerobic gram-negative bacillus that most commonly causes infection in immune-compromised hospitalized individuals, especially those with hematologic malignancy, neutropenia, and history of treatment with broad-spectrum antibiotics. This infection has been known to affect multiple organ systems, but cutaneous involvement has been increasingly recognized over the years, albeit still relatively rare. Here we report a case of ulcerations on the palm and wrist, which were found to be positive for S. maltophilia. We also review the various skin and mucocutaneous findings that have been reported with this organism as well as treatment for this often multiple drug resistant organisms.
