Hyalinizing segmental vasculitis or livedo vasculitis (atrophie blanche) is a clinical entity with a distinctive immunohistopathologic morphology that can be distinguished from other forms of cutaneous vasculitis by histologic and direct immunofluorescent studies. Our studies showed that immunoglobulins and complement components (C-1g, C-3, and properdin) were localized in diseased vessel walls, suggesting an immune pathogenesis.

Arnold L. Schroeter (1975) conducted an observational in Livedo vasculitis (atrophie blanche). Histologic and direct immunofluorescent studies vs. Other forms of cutaneous vasculitis was evaluated on Localization of immunoglobulins and complement components in diseased vessel walls. Histologic and direct immunofluorescent studies in livedo vasculitis localized immunoglobulins and complement components (C-1g, C-3, properdin) in diseased vessel walls.
