Recurrent pneumonias often occur in the setting of an airway obstruction and can be the presenting symptom of an undiagnosed malignancy. Little is known regarding the microbiology of these pneumonias making antibiotic therapy difficult to direct; however, the few studies available show these pneumonias to be polymicrobial. Examining the colonization patterns of at-risk populations such as patients with chronic obstructive pulmonary disease and using techniques such as ultrasound and computed tomography-guided biopsies may help in the treatment of these pneumonias. The following review is presented to highlight the current medical knowledge as well as suggest areas for future evaluation.
