Case report: Yersinia enterocolitica necrotizing pneumonia in an immunocompromised patient.

The authors report a rare case of Yersinia enterocolitica necrotizing pneumonia in an immunocompromised patient, who responded with resolution of the infection after 6 weeks of therapy with a third-generation cephalosporin but subsequently expired from the underlying lymphoma. In the few cases of Y. enterocolitica pulmonary infections that have been reported, the prognosis for cure of the infection is excellent with appropriate antibiotic therapy. Y. enterocolitica is likely to be recognized more frequently as a cause of serious infection in the growing immunosuppressed population. Early recognition and appropriate therapy can improve survival significantly.
