title: A novel cause of community-acquired pneumonia in a young immunocompetent host.
abstract: Diffuse pulmonary infiltrates represent a common problem encountered by pulmonologists. The differential diagnosis is extensive and includes infectious, inflammatory, environmental and malignant conditions. Appropriate evaluation, aside from a thorough history and physical examination, includes serologic, radiographic and procedural elements. We describe a case of a healthy male with diffuse pulmonary infiltrates. Work up revealed a novel infectious etiology. Although this particular microorganism has been described to cause native valve endocarditis, recurrent breast abscesses, osteomyelitis and bacteremia, it has to date not been described as a cause for community acquired pneumonia in immunocompetent hosts.
