孤立性肺類上皮血管内皮腫の1例

Pulmonary Epithelioid Hemangioendothelioma：Report of a Case

はじめに　肺類上皮血管内皮腫（pulmonary epithelioid hemangioendothelioma：PEH）は血管内皮細胞由来の低～中悪性度のまれな腫瘍であり，確立された治療法はない．われわれは孤立性PEHの手術例を経験したので報告する．

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）.
