title: Chronic Klebsiella pneumonia: a rare manifestation of Klebsiella pneumonia.
abstract: K. pneumoniae can present as two forms of community-acquired pneumonia, acute and chronic. Although acute pneumonia may turn into necrotizing pneumonia, which results in a prolonged clinical course, it often has a rapidly progressive clinical course. In contrast, chronic Klebsiella pneumonia runs a protracted indolent course that mimics other chronic pulmonary infections and malignancies. Herein, we present two cases of chronic Klebsiella pneumonia. The diagnosis was made by microorganism identification, as well as absence of other potential causes. Clinical and radiographic findings improved after a prolonged course of antibiotic therapy.
