A case of soft tissue infection by Stenotrophomonas maltophilia manifesting as subcutaneous nodules in a patient with leukemia / 대한내과학회지

ABSTRACT

Stenotrophomonas maltophilia is a ubiquitous, Gram-negative organism. It is an emerging causative pathogen for severe hospital- acquired infections, particularly in debilitated or immunocompromised patients because of its resistance to various antibiotics. Soft tissue infection caused by S. maltophilia, however, is uncommon. A patient with leukemia was referred for the evaluation of subcutaneous nodules that developed after chemotherapy. With the pathological finding of neutrophilic panniculitis, S. maltophilia was confirmed in a bacteriological study of the biopsied tissue. The nodules regressed spontaneously with recovery from the neutropenia. We report a case of S. maltophilia infection that manifested as soft tissue nodules, which resolved spontaneously in a patient with leukemia.
