Immunofluorescence studies in scabies.
Direct and indirect immunofluorescence investigations performed for 11 patients with scabies. All patients had punch biopsies taken from (1) a lesion containing Sarcoptes scabiei, (2) an inflammatory papule which did not contain a mite, and (3) normal skin. In four patients IgE deposits were found in the vessel walls of the upper dermis both in biopsies containing mits and biopsies of inflammatory papules with no mites. No IgE deposits were found in biopsies of normal skin from the same patients. Two patients had IgM and/or C3 deposits along the basal membrane in biopsies containing mites and one of them also had C3 in this area in the biopsy from a papule with no mite, as well as normal skin.
