Eosinophilic Pneumonia with Eosinophilic Gastroenteritis

A 48-year-old man was admitted to our hospital with cough, fever and dysphagia. He had a past history of bronchial asthma and surgery for nasal polyp. Chest radiograph and computed tomography showed atelectasis in the right lower field and infiltrative shadow in the left lower field and overall thickening of the esophageal wall. Transbronchial lung biopsy (TBLB) specimens revealed infiltration of eosinophils and lymphocytes under the bronchial mucosa. Gastrointestinal tract biopsy specimens showed submucosal infiltration of eosinophils. These findings led to a definite diagnosis of eosinophilic pneumonia associated with eosinophilic gastroenteritis, a disease which has been rarely reported. (Internal Medicine 38: 450-453, 1999)
