[Chronic eosinophilic pneumonia presenting as a solitary nodule, suspicious of lung cancer;report of a case].

A 70-year-old man was followed up at the surgery department of our hospital after colon polypectomy. It was pointed out that the level of carcinoembryonic antigen(CEA) was high at blood test. Chest computed tomography (CT) showed small nodule close to the pulmonary vein in the right lower lobe (S6-S10), 15 mm in size, in September 2011. Fluorodeoxyglucose-positron emission tomography( FDG-PET)/CT scanning revealed a positive reaction in the right lower lobe lesion. He was introduced to our department. The video-assisted thoracoscopic surgery (VATS) was performed to establish diagnosis and treat. Histopathological examination showed no malignancy and chronic eosinophilic pneumonia(CEP).In a case of the solitary lung nodule patient with the past history of asthma or the atopic disease, CEP should be included in the differential diagnosis.
