肺上皮样血管内皮瘤的研究进展

Epithelioid hemangioendothelioma (EHE) is a rare vascular neoplasm that develops from vascular endothelial cells. It has been reported to occur many sites of body, but the most common EHE presentations are soft tissue (limbs), bone, liver and lung. Compared with other pulmonary tumors, pulmonary epithelioid hemangioendothelioma (P-EHE) is relatively rare. According to a literature review, more than 100 cases have been described all over the world. Due to the low incidence of P-EHE, lack of specificity in clinical symptoms and radiological findings, it is often misdiagnosed. Meanwhile, many patients do not receive appropriate treatment, resulting in poor prognosis in some cases. Histology and immunohistochemical methods are essential for diagnosis. However, there is no established standard treatment for P-EHE, because of the rarity of the disease. When the lesions are small and limited in number, surgical is the best treatment, achieving the purpose of diagnosis and treatment at the same time. This article tries to present the etiopathogenesis, clinical manifestations, diagnosis, treatment and prognosis of P-EHE.
