[Occupational allergic asthma in a laboratory animal keeper with COPD].

This is a case report of a 63-year-old woman, who had worked as a laboratory animal keeper for 23 years. She developed increasing symptoms of rhinitis, coughing and shortness of breath and was diagnosed and treated for COPD based on her smoking history and spirometry results. She went on sick leave due to dyspnoea, and after testing she was diagnosed with occupational allergic asthma from rodents. Her lung function was at this point significantly reduced. Occupational asthma is common, and occupational causes of respiratory symptoms should always be taken into consideration when assessing patients in the working population.
