Background. Lung abscesses require to be distinguished from lung cancer on imaging findings such as FDG-positron emission tomography (PET) or chest computed tomography (CT). Case. A 70-year-old man was referred to our hospital with an abnormal shadow on a chest X-ray film. A chest CT scan revealed a pulmonary mass in the right S6 invading the right S2. Transbronchial lung biopsy and brushing cytology did not reveal any evidence of malignancy or inflammatory pulmonary disease such as tuberculosis. A diagnosis of malignant disease, including lung cancer, could not be excluded because of a slight increase in the SCC tumor marker and FDG uptake on PET-CT. We conducted resection, and the histopathological findings of the resected specimen showed an infiltration of inflammatory cells of lymphocytes, macrophages and neutrophils with a proliferation of fibrin. However, there was no evidence of malignancy. We finally made a diagnosis of a lung abscess. Conclusion. We report a case of lung abscess which needed to be distinguished from interlobar P3 lung cancer.
