摘要
通过3例登革出血热皮疹处皮肤病理切片检查,对皮疹的发生、消退、病理改变、病变处血管等超微结构进行观察。结果显示登革出血热皮疹的主要病理改变为真皮上层血管内皮细胞的变性,致使红细胞外溢。推论内皮细胞的病变与病毒感染相关。
Evaluation of histopathological and ultrastructural changes in skin eruptions of three dengue hemorrhagic fever patients Was performed. The main pathological findings in skin lesions were swelling of the endothelial cells in small vessels of papillary dermis, diapedesis of neutrophils, extravasation of erythrocytes and perivascular lymphocytes infiltration. Ultrastructural observation revealed degen erration of endothelial cells and neutrophils. The results suggest that the damage of vascular endothelium with viral infection correlated rather well with hemorrhage
