Localized chronic pemphigoid. Report of a case, review of the literature and discussion of the relationship with cicatricial pemphigoid.

A case of a chronic remittant blistering eruption on the left temple in a 62-year-old woman is described. Only after repeated biopsies did direct immunofluorescence (DIF) studies reveal a linear staining of the epidermal basement membrane with anti-IgG, C1q, C4, C3 and C5. In addition, heavy deposits of fibrin were observed. The importance of repeated DIF examination in initially negative cases has been stressed. Localized chronic pemphigoid should be considered as a distinct subform of the pemphigoid syndrome.
