궤양성 대장염 환자에서 메살라진 좌약으로 인하여 재발한 호산구성 폐렴

Mesalazine suppositories are widely used to treat ulcerative colitis and have a guaranteed safety profile, but although rare, they can cause pulmonary toxicity. A 35-year-old woman with ulcerative colitis was diagnosed to have acute eosinophilic pneumonia after 29 days of oral mesalazine use and improved after mesalazine and corticosteroid were withdrawn. Reintroduction of mesalazine suppositories resulted in acute eosinophilic pneumonia recurrence after 28 days. Mesalazine re-administration (even via a different route) in patients with a history of mesalazine-induced eosinophilic pneumonia should be undertaken cautiously, because eosinophilic pneumonia may recurrence.
