Liver abscess caused by Stenotrophomonas maltophilia: report of a case.
We report the case of a melioidosis-like abscess of the liver caused by Stenotrophomonas (Xanthomonas) maltophilia infection in a Chinese man living in Hungary. Although this appears to be the first documentation of a liver abscess of this origin in a nonimmunocompromised patient, our case report demonstrates that this common facultative pathogen can also cause liver abscess and sepsis. After repeated negative blood cultures, histological examinations of liver biopsies suggested the possibility of chronic melioidosis, but the microbiological examination performed directly on the same specimen identified a Stenotrophomonas maltophilia infection. Surgical drainage was performed and sulphamethoxazole/trimethoprim therapy was commenced, after which the patient recovered fully. The facultative pathogen S. maltophilia, which most often causes nosocomial infections, may cause severe sepsis and liver abscess. We wish to draw attention to the fact that the antibiotic sensitivity of S. maltophilia is not necessarily the same in vivo and in vitro. This can create difficulties in both diagnosis and treatment.
