Normal structure of nail fold capillaries as observed by capillaroscopy and fluoroscopy is recalled. A procedure of proximal nail fold biopsy is described. The technique is simple without disadvantage for patients. Tissue from the proximal nail fold is studied in three different ways: light microscopy with histochemistry, electron microscopy and direct immunofluorescence. In the two normal cases studied, usual epidermal and dermal components are found. Some particular point may be emphasized: sweat's droplets draining of distal part of proximal nail fold, numerous and large nervous structures, capillaries basal lamina multiplication.
回顾了通过毛细血管镜检查和荧光检查所观察到的甲襞毛细血管的正常结构。描述了一种近端甲襞活检的方法。该技术简单，对患者没有不利影响。从三个不同方面研究近端甲襞组织：组织化学光镜检查、电子显微镜检查和直接免疫荧光检查。在所研究的两例正常病例中，发现了常见的表皮和真皮成分。可以强调一些特殊之处：近端甲襞远端部分的汗腺液滴排出、大量且粗大的神经结构、毛细血管基底膜增生。
