Important diagnostic phenomenon in psoriasis. After removal of the uppermost parakeratotic horny scales, punctiform bleeding occurs, which in this form is only found in psoriasis. This phenomenon had already been described in 1867 by F.v. Hebra in his atlas as "bleeding dew" and was mentioned by Robert Willan (1808), Josef Plenck (1776). The Auspitz sign is today associated with the name Auspitz, because H. Auspitz made this diagnostic feature known as such.
