title: [Isolated pemphigus vulgaris of the mouth mucosa--pemphigus test: diagnostic confirmation using direct immunofluorescence study of normal skin].
abstract: The diagnosis of oral pemphigus vulgaris (PV) without concomitant cutaneous manifestations is often complicated by difficulties in obtaining a biopsy specimen allowing histological examination and direct immunofluorescence (IF) microscopy. In this clinical study five of our patients with oral PV were investigated: biopsies were taken both from lesional oral mucous membranes and from unaffected gluteal skin for IF analysis. Identical IF results, with intercellular epidermal deposition of IgG in all and of C3 in two of the five cases, were obtained in lesional and nonlesional biopsies. Therefore, it is concluded that with current IF techniques examination of the normal skin is sufficient for the diagnosis of oral PV; thus, the often painful and difficult removal of biopsy specimens from within the affected oral cavity can be avoided. Further studies are needed to confirm the sensitivity of this method.
