Introduction

 
In part I of our series titled Understanding "livedo vasculitis," we addressed all terms associated with "livedo" and with "livedo vasculitis" in historical perspective.[1] By way of comparison of what is written and pictured in articles from the past, we concluded that Milian (1929) [2], Gougerot et al (1936) [3], O'Leary (1944, 1955) [4,5], Ellerbroek (1953) [6], Nelson (1955) [7] Feldaker et al (1955, 1956) [8,9], Schuppener (1957) [10], Gray et al (1966) [11], Bard et al (1967) [12], Winkelmann et al (1974) [13], Gilliam et al (1974) [14], Milstone et al (1983) [15], McCalmont et al (1992) [16], and Papi et al (1998) [17] told of the very same disease entity, even though they gave 14 different names to it. For purposes practical, we suggested to refer to this condition as "Livedo vasculitis" (LV), the issue of whether or not the disease represents a vasculitis being addressed at the end of this article. In this, the second part of our series, we elaborate in detail findings clinical and histopathologic as they can be found in articles about patients diagnosed with LV (or with one of the designations used synonymously with it). We present collections verbatim from articles about LV in regard to morphologic findings and our comments on them. In the end we attempt to answer intriguing questions about LV by way of clinicopathologic correlation and we illustrate our considerations with photomicrographs of sections of LV, which come from 7 different patients. In the third and last part of this series, pathogenesis and etiology of the condition will be discussed.
