Histopathological and immunofluorescent findings of PNP. (A,B) Suprabasal acantholysis (A) and interface dermatitis with scattered dyskeratotic cells (B) are observed in PNP skin lesions (scale bar, 100 μm). (C,D) Using indirect immunofluorescence studies, IgG deposition on the intercellular spaces of keratinocytes and the dermo–epidermal junction (C) and on the surface of rat bladder epithelial cells (D) is found (scale bar, 100 μm).
