Abstract
We present four cases of perianal synergistic gangrene in severely immunocompromised patients. In all patients, gangrene was controlled by radical surgery, including defunctioning colostomy in three patients, backed up by appropriate antibiotic therapy. Three of the patients survived and left the hospital; the fourth died in the intensive care unit of overwhelming sepsis from an unidentified source other than the anus. We review the literature and conclude that such infections in these patients are not inevitably fatal and that radical surgery can result in a cure.
