ABSTRACT
Bird-related hypersensitivity pneumonitis (BRHP) occurs with repetitive inhalation of antigens attributed to bird-related proteins. To identify the antigen triggering BRHP, specific antibody measurement and a lymphocyte proliferation test (LPT) are useful, but those tests are performed only at limited research institutes. The present case was a 49-year-old woman who had owned an owl for nine years. Over three months, she gradually displayed symptoms of dyspnea, chronic cough, and urticaria that led to her admission to our hospital following which those symptoms soon disappeared. Her LPT showed positivity for the owl’s feather. We therefore report a case of BRHP with urticaria due to owls' feathers.
