title: [Intravascular papillary endothelial hyperplasia of the lung].
abstract: We report a rare case of pulmonary intravascular papillary endothelial hyperplasia. The patient was a 63-year-old male. Multiple lung nodules were noted on chest computed tomography( CT) at preoperative check for gastric cancer. Metastatic lung tumor was suspected, and partial resection of the right lung was performed. Histopathologic examination revealed papillary proliferation lined by endothelial cells and a hematoma. Immunohistochemically, the endothelial cells were positive for CD31/CD34 and factor VIII related antigen.
