Veins of the dermis have been investigated mainly by histological methods in the fields of anatomy and histology, and a large number of schemata of the veins have been depicted in a variety of textbooks. However, the schemata are usually two-dimensional and it is therefore difficult to envisage the actual vasculature of the dermal veins. In this study, we performed a stereographic study of the skin of three fresh cadavers that had been injected with radio-opaque dye, which was dispersed throughout the entire body. A venous network consisting of venous polygons of various sizes existed just under the dermis or in the deep zone of the dermis, which is generally called the subdermal venous plexus. There were many small vessels towards the inside of each venous polygon, and most of them ascended, branching off stereoscopically. Those branches anastomosed with each other, and they formed the dermal and subpapillary venous plexuses. However, there was little vascular connection between dermal venous plexuses of different venous polygons. The characteristic structure of the dermal venous plexus has been considered to bring about venous congestion of the skin in various clinical situations.
