title: Citrobacter koseriPneumonia As Initial Presentation of Underlying Pulmonary Adenocarcinoma.
abstract: Citrobacter koseriis a motile, gram-negative rod traditionally known to cause infection in individuals with significant comorbidities and immunocompromised status. While most cases represent nosocomial infections, rarely community-acquired infections have been reported. We present a previously healthy man in his 60s withC. koseripneumonia who was subsequently found to have underlying pulmonary adenocarcinoma, illustrating the need for further investigation for immunodeficiency and/or intrapulmonary pathology.
