title: Pulmonary sclerosing pneumocytoma mimicking lung cancer: Case report and review of the literature.
abstract: Pulmonary sclerosing pneumocytoma (PSP) is a rare benign neoplasm that predominantly affects middle-aged Asian women. PSP is often asymptomatic and demonstrates a solitary pulmonary nodule on radiologic examination. We report a case of PSP initially misdiagnosed as lung cancer because of strong (18)F-fluorodeoxyglucose (FDG) uptake revealed by (18)F-FDG positron emission tomography-computed tomography scan. After surgery, pathology revealed that the tumor cells were immunopositive for epithelial membrane antigen and thyroid transcription factor-1. The patient has been followed up without complication or recurrence.
