An electron microscopic study was carried out of different kinds of hemangiomas (capillary, cavernous and combined) in 18 children at the age of two months up to one year. Centers of differently expressed proliferation both of the endothelial cells and pericytes were found. The proliferation was most distinctly expressed in the capillary and cavernous hemangiomas. At the later stages, regressive and involutive changes, presented better in the capillary hemangiomas, were observed. The authors consider that hemangiomas, irrespective of their active cell growth, are tumours with a good prognosis.
对18名年龄在两个月至一岁之间的儿童的不同类型血管瘤（毛细血管瘤、海绵状血管瘤和混合型血管瘤）进行了电子显微镜研究。发现了内皮细胞和周细胞增殖表达不同的中心。这种增殖在毛细血管瘤和海绵状血管瘤中表现最为明显。在后期，观察到退行性和 involutive 变化，在毛细血管瘤中表现得更为明显。作者认为，血管瘤无论其细胞生长多么活跃，都是预后良好的肿瘤。 （注：这里“involutive”没有完全对应的中文词汇，暂保留英文，也可根据语境理解为“退化性的”之类意思）
