摘　　要：目的观察儿童卡波西型血管内皮瘤(KHE)的超声与病理学表现。方法纳入31例经病理学证实的KHE患儿,观察其超声及病理学表现;将患儿分为KHE组(n=22)与合并卡萨巴赫-梅里特现象(KMP)组(n=9),对比组间超声表现。结果31例KHE患儿的中位年龄为3个月,其中24例(24/31,77.42%)于婴儿期发病;29例(29/31,93.55%)可见单发、2例(2/31,6.45%)见多发病灶,部位多变;9例伴KMP。KHE超声多表现为形态不规则、边界不清,病理提示细胞增生明显;病灶以中等偏强回声为主,病理未见淋巴管或纤维结缔组织成分;内部血流信号丰富,病理见呈肾小球样排列增生的血管团,免疫组织化学CD34(+)。合并KMP组病灶累及深度大于KHE组(P<0.05),其余超声表现,包括回声及血供等组间差异均无统计学意义(P均>0.05)。结论KHE超声多表现为边界不清的不均匀中等偏强回声,内部血流信号丰富,与其病理学成分密切相关;合并KMP时病灶浸润程度更深。Objective To observe the ultrasonic and pathological manifestations of Kaposi form hemangioendothelioma(KHE)in children.Methods A total of 31 children with pathologically confirmed KHE were enrolled,and the ultrasonic and pathological manifestations were observed.The children were divided into KHE group(n=22)and combining Kassabach-Merrit phenomenon(KMP)group(n=9).The ultrasonic findings were compared between groups.Results The median age of children in KHE was 3 months,among them 24 cases(24/31,77.42%)were developed in infancy.Single lesion was observed in 29 cases(29/31,93.55%),while multiple lesions were detected in 2 cases(2/31,6.45%),and the sites of KHE were varied.KMP was noticed in 9 cases.Ultrasonography showed that KHE lesions were irregular shaped,with unclear boundaries that pathology suggested obvious cell proliferation,medium to strong echo which pathology suggested no lymphatic vessels or fibrous connective tissue components,as well as rich inside blood flow,pathology showed glomerulus-like arrangement and proliferation of blood vessel clusters and immunohistochemistry CD34(+).In combining KMP group,only the depth of lesion involvement was deeper than that in KHE group(P<0.05),while other ultrasonic findings,such as echo and blood supply,were not significant different between groups(all P>0.05).Conclusion Ultrasonography depicted that most KHE lesions present uneven and medium to strong echo with unclear boundary and rich inside blood flow signals,closely related to pathological components of KHE.The depth of KHE infiltration was deeper in children with KMP.
