A Case of Livedo Vasculitis / 대한피부과학회지

ABSTRACT

Livedo vasculitis or vasculitis of atrophie blanche is a clinical entity which can be distinguished from cutaneous vasculitis by distinctive pathology and immunopathologic study. A 18-year-old female with erythematous, telangiectatic, purpuric or hyperpigmented patches, intermingled with white atrophic ivory patches on her legs of 3 years duration was seen in June 3, 1982. The histologic examination of an atrophic patch showed proliferation and occlusion of blood vessels in the upper dermis with patchy atrophy of the epidermis. The immunopatbologic features of an atrophic patch revealed deposits of IgM, Ca and fibrin as a definitive immunofluorescence vessel pattern. This suggests that the livedo va.sculitis or vasculitis of atrophie blanche may he considered one of the immune vasculitides. This patient had received aspirin and persantine for 4 months, and moderate therapeutic effects could be noticed.
