The characteristic histologic change seen at 2 h in the Rumpel-Leede (Hess) test is, in addition to focal hemorrhage in the upper dermis, a perivascular lymphocyte infiltrate with focal areas of lymphocytic epidermal invasion. The histologic findings, even with the liquefaction degeneration, are similar to those of purpura simplex and indicate that, early in many forms of vasopermeability, the lymphocyte may be a primary inflammatory cell.
在束臂试验（赫斯试验）中，2小时时可见的特征性组织学变化，除了真皮上层的局灶性出血外，还有血管周围淋巴细胞浸润以及淋巴细胞灶性侵入表皮的区域。即使伴有液化变性，组织学表现也与单纯性紫癜相似，这表明在许多形式的血管通透性增加的早期，淋巴细胞可能是主要的炎症细胞。
