abstract: An 84-year-old man with massive verrucous lesions in the intertriginous areas is reported. The clinical, histological and electron microscopical findings indicated pemphigus vegetans. However, in addition to the intraepidermal findings direct immunofluorescence showed a linear deposit of IgG and C3 at the basement membrane.
