摘　　要：目的探讨淋巴结内淋巴窦血管转化(VTS)的组织病理形态学特征。方法7例VTS进行组织学观察,组织用福尔马林固定、石蜡包埋、HE染色。结果淋巴结结构弥漫性或局限性消失,血管增生伴泡沫状组织细胞浸润。增生的血管有四种基本类型厚壁型血管、裂隙状血管、海绵状血管、透明血管。结论淋巴结内淋巴窦血管转化为一增生性疾病,非真性肿瘤,主要应与淋巴结病型Kaposi肉瘤鉴别。Objective ：To investigate histopathologie characteristics vascular transformation of sinuses （VTS） in lymph nodes. Methods：Specimens were fixed with formalin, paraffin-embedded and hematoxylin-eosin-stained. Results：Nodes structure was diffusely or segmentally disappeared. Proliferated vessels were associated with foamy macrophages infiltration. Four major patterns of vascular proliferation were observed. （ 1 ） Thick-walled vessels; （ 2 ） Cleft-like vessels ; （ 3 ） Cavernous vessels; （ 4 ） Hyalinization-walled vessels. Conclusion： Vascular transformation of sinuses in lymph nodes is a benign noded vasoproliferative lesion, and not a true tumor, but must distinguish it from Kaposi sarcoma in lymph nodes.
