Immunofluorescent and histologic study of cold urticaria.
Biopsies of spontaneous and ice-induced wheals of five patients with cold urticaria showed two types of lesions: one with predominant neutrophils and one with predominant lymphocytes. Immunofluorescent studies of the five cases showed nonspecific findings in two cases and negative findings in three cases.
