Background. Pulmonary epithelioid hemangioendothelioma (PEH) is a rare tumor of the lung deriving from vascular endothelial cells. Case. A 19-year-old woman was referred to our hospital because of an abnormal shadow on her chest X-ray film. Chest radiograph and CT on admission showed well-defined multiple small nodules in bilateral lung fields. As pathological findings of specimens resected by video-assisted thoracoscopic surgery revealed atypical epithelioid cells and stained for factor VIII-related antigen and CD34, a diagnosis of pulmonary epithelioid hemangioendothelioma was made. She was given no medication but has no symptoms without specific medication for 2 years after her first admission, although chest CT findings demonstrated mild progression of the disease. Conclusion. We report a case of pulmonary epithelioid hemangioendothelioma found on a school medical check up.
