Nine patients were female and one male (ages 31-77, average 52 years). Six patients presented parenchymal vascular lesions (1 angiosarcoma, 1 atypical hemangioma, 3 perilobular hemangiomas, 1 cavernous hemangioma) measuring 0.5-6 cm in the greatest diameter. Two lesions were accidental findings in lumpectomy specimens excised for fibrocystic disease with microcalcifications. Four patients presented non-parenchymal vascular lesions: three cavermous hemangiomas and one angiolipoma measuring 1-6 cm in diameter.

女性9例，男性1例（年龄31-77岁，平均52岁）。6例表现为实质血管性病变（血管肉瘤1例，不典型血管瘤1例，小叶周围血管瘤3例，海绵状血管瘤1例），大小0.5-6cm.2例因乳腺纤维囊型病变伴微钙化在切除的标本上偶然发现。4例呈非实质性的血管病变，其中海绵状血管瘤3例（1例为男性），1例为血管脂肪瘤，最大直径为1.6cm。

It is possible that atypical perilobular hemangiomas or atypical hemangiomas are precursors to angiosarcoma, but this relationship remains to be demonstrated.

不典型小叶周围血管瘤或不典型血管瘤可能是血管肉瘤的前驱病变，但这种相关性尚需要进一步证实。

Methods: The specimens were taken from 30 proliferative hemangiomas, 22 involuting hemangiomas,27 vascular malformations and 5 samples of normal skin.

皮肤血管瘤是婴幼儿较常见的一种良性血管增生性肿瘤，其增生、消退机制至今不明。

objective:to investigate the expression and significance of rb in the occurrence, development and regression of infantile hemangiomas.methods:the expression of rb was examined in the proliferative stage and catagen of human hemangiomas and normal skin tissues by using immunohistochemical technique.immunohistochemical technique for factorⅷ-related antigen was used to prove that the cells which expressed rb were endothelium.image analysis system was applied to measure the expression level of rb at different stages of hemangiomas and in normal skin tissues.results:the expression of rb was significantly lower in proliferating hemangiomas than that in involuting hemangomas(p.05).conclusion:rb might play an important role in the regression of human hemangioma endothelial cells and anti-angiogenesis.

目的：探讨rb蛋白在血管瘤发生、发展及退化过程中的表达状况及其意义。方法：采用免疫组织化学方法检测人皮肤血管瘤增生期、退化期及正常皮肤组织中rb的表达水平，并结合第ⅷ因子相关抗原的免疫组织化学染色证实表达rb的细胞是血管内皮细胞。利用计算机图像分析技术测量不同时期血管瘤组织和正常皮肤组织rb表达的积分光密度和面积。结果：增生期血管瘤内皮细胞rb表达水平低于退化期，差异有显著性（p.05），退化期血管瘤内皮细胞rb表达水平与正常皮肤组织相比，差异有显著性（p.05）。结论：rb通过抑制血管瘤内皮细胞增殖和血管生成而在血管瘤的退化过程中起重要作用。
