The angioarchitecture of the skin of the retroauricular area of a 25-year-old and a 55-year-old man was studied by scanning electron microscopy of vascular corrosion casts. Special attention was paid to the arrangement of the capillary bed of the stratum papillare corii. There is an average of 40 capillary loops per mm2. The diameters of the ascending loops of the capillaries range between 12.3 and 15.3 microns, of the descending ones between 19.0 and 22.9 microns, the length of the capillary loops is between 326 and 407 microns. The range of confidence is 95 percent. Three different patterns of arteriovenous anastomoses were found within the papillary and partly in the subpapillary capillary bed. The results showed no difference between the vascular beds of the two men. The scanning electron microscopy of vascular corrosion casts and its significance in the normal and pathological vascular bed is discussed.
