脾窦岸细胞血管瘤(1ittoral cell angioma,LCA)又称衬细胞血管瘤,是仅发生于脾脏的一种较为罕见的、具有特殊病理形态学及免疫学特征的良性肿瘤。该肿瘤来源于脾窦岸细胞,而窦岸细胞属于网状内皮细胞系统,因此,它具有向内皮细胞及组织细胞双向分化特点。LCA于1991年由Falk~([1])首次报 Splenic sinus shunt (1ittoral cell angioma, LCA), also known as lining hemangiomas, is a relatively rare type of benign tumor that occurs only in the spleen and has special pathological and immunological features. The tumor originates from the splenic sinusoidal cells, while the sinusoid cells belong to the reticuloendothelial system, and therefore, it has the characteristic of bidirectional differentiation into endothelial cells and tissue cells. LCA was first reported by Falk ~ ([1]) in 1991
