title: Organizing pneumonia presenting after ulcerative colitis remission.
abstract: Ulcerative colitis (UC) is the most common form of inflammatory bowel disease worldwide, and extraintestinal manifestations (EIMs) involving various organs and systems occur in 10% to 30% of patients. Recently, although the pulmonary manifestation of UC is being increasingly recognized, these manifestations are described much less frequently than other EIMs. Furthermore, organizing pneumonia (OP) involving the lung parenchyma is a relatively uncommon pulmonary manifestation of UC, and to our knowledge, no case of OP after histologically confirmed UC remission has been previously reported in the English literature. Here, we present a case of OP after remission in an elderly female with a history of UC.
