Respiratory impairments occurring as systemic manifestations of ulcerative colitis are often misinterpreted. We report a case of chronic productive bronchitis associated with ulcerative colitis; symptoms appeared after colectomy. Clinical features distinguished it from common chronic bronchitis: it occurred in a woman without respiratory disease or smoking history, a chronic productive cough without bronchiectasis, negative infectious investigations, severe endoscopic and histologic lesions, and above all remarkable steroid efficacy. Systematic research and early treatment of these manifestations avoids aggravating pulmonary disease, especially secondary bronchiectasis. Though less frequent, other respiratory manifestations of ulcerative colitis have been described, such as asphyxiating tracheal stenosis, pneumonia or interstitial pulmonary diseases, pleurisy or pleuro-pericarditis.
