Abstract

Nine selected cases of a chronic, recurrent. segmental hyalinizing vasculitis of the dermis are presented. Heretofore, many of these cases had been classified as livedo reticularis with ulceration, but none of the patients in this series had livedo. The cutaneous findings are limited to the lower extremities and may include a patchy livedo-like pattern of purpura, ulcers, and, in the healed phase, scars which resemble atrophie blanche. Pathologically, this is a process of relatively noninflammatory endothelial proliferation, subintimal hyalinization, and focal thrombosis in the vessels of the middle dermis of unknown cause.
