Organizing pneumonia is an interstitial lung disease, which occurs with distinctive clinical, imaging, and histomorphological findings in patients. The histopathologic characteristics of organizing pneumonia are the presence of myofibroblastic plugs in the lumens of the respiratory bronchioles, alveoli, and alveolar ducts. Organizing pneumonia may be cryptogenic or secondary to different known reasons. It can also develop secondary to aspiration. Foreign body aspiration is less common in adults than in children. It may appear as a serious medical problem that endangers life, especially in the older age group. In this article, we present a case of organized pneumonia that developed secondary to bone fragment aspiration in an elderly patient with characteristic histological findings.
