Ecthyma gangrenosum in a kidney transplant recipient with pseudomonas septicemia

This report describes a renal transplant recipient in whom Pseudomonas septicemia and ecthyma gangrenosum developed within days of renal transplantation. Microscopic skin sections showed perivascular bacillary invasion. Pseudomonas organisms were cultured and microscopically visualized in sections from the transplanted kidney. Although cultures from the donor kidney preservation perfusate fluid showed no growth, Pseudomonas aeruginosa was found in the recipient's urine, blood, and peritoneal fluid. The recipient's course was complicated by septic shock, cardiopulmonary arrest, coma, and extensive skin lesions; but his condition improved with appropriate antibiotic therapy, wound debridement, and an aggressive rehabilitative program. He is now a candidate for retransplantation. This is the first known case of ecthyma gangrenosum in a renal transplant recipient.
