title: Deposits of immunoglobulins and complement in the dermoepidermal junction of patients with anaphylactoid purpura.
abstract: Skin biopsies from 3 patients with anaphylactoid purpura examined by an immunofluorescence technique revealed deposits of immunoglobulins, complement C3, and fibrinogen in the dermo-epidermal junction and in vessel walls of clinically involved as well as uninvolved skin. The deposits in the dermo-epidermal junction are similar to those seen in the skin of patients with systemic lupus erythematosus.
