title: [Eosinophilic pneumonia presenting as a mass shadow].
abstract: A 35-year-old man underwent routine chest roentgenography and a mass shadow was seen in the left lung field. Examination of a transbronchial lung biopsy specimen revealed that many eosinophils had infiltrated under the bronchial mucosa and into the alveolar septum. The total serum IgE concentration was high, and skin tests with Aspergillus antigen and serum precipitating antibodies against Aspergillus were positive. The mass lesion disappeared without any therapy, and a cystic lesion remained. Mediators released from eosinophils were thought to have damaged the lung tissue. We should have administrated corticosteroids as soon as possible.
