    Abstract:
    A case of pulmonary eosinophilic granuloma which arose rapidly after 30 years of smoking and remitted spontaneously without smoking cessation is reported. The patient was a 54-year-old man complaining of a dry cough who had been smoking 30 cigarettes a day for 30 years. Chest roentgenography showed multiple nodular shadows and cystic lesions in the upper and middle fields of both lungs. Chest computed tomography revealed multiple small cysts and small nodular lesions, mainly in both upper lung fields. CT findings strongly suggested pulmonary eosinophilic granuloma. A transbronchial lung biopsy (TBLB) was performed and 4 specimens were obtained, of which 3 showed granulomatous lesions with eosinophils and histiocytes. Furthermore, the granulomatous lesions were positive for S-100 protein staining. The symptoms and radiographic findings improved markedly within about 6 months after the onset of symptoms without treatment. Many cases of this disease were diagnosed in the past by open lung biopsy, but the number of cases diagnosed by TBLB is now increasing. The effectiveness of open lung biopsy has been emphasized in the diagnosis of pulmonary eosinophilic granuloma, but TBLB is also useful for diagnosis, especially in the active or early stage of the disease.
