A 54-year-old woman with a lung tumor was admitted to our hospital for surgical treatment. Chest computed tomography (CT) showed a 16×14×10 mm nodule in left upper lobe. Flurodeoxyglucose (FDG)-positron emission tomography (PET)/CT revealed increased uptake in the nodule. We diagnosed the tumor as lung cancer preoperatively, and performed surgery. Frozen section diagnosis after partial lung resection was lung cancer and we performed left upper lobectomy. The tumor was histopathologically diagnosed as pulmonary epithelioid hemangioendothelioma( PEH).
