In this paper, an attempt is to be made to demonstrate a mechanism of production of progressive pigmentary purpuric disorders, or dermatitis associated with an increased capillary fragility. These "capillaroses," as we shall see, are of mixed etiology, but it is hoped in this paper to shed some light in particular on the condition originally described by Schamberg in 1900,1 and to which his name is now attached. In Schamberg's first case, the patches are described as sharply defined; of reddish-brown color; varying in size; while at the border are visible a number of small outlying macules of the same color and of the size of pinheads.
