The immunofluorescence pattern in adnexal structures may be of value, especially when the epidermis is not well represented in diagnostic sections. We studied a total of 88 cases of pemphigus vulgaris ( PV ) and bullous pemphigoid ( BP ) accessioned between 2010 and 2015 (40 cases of PV and 48 cases of BP ). Immunofluorescence patterns and sensitivity in adnexal structures were similar to those observed in the epidermis. One case of PV and three cases of BP showed weak or absent fluorescence in the epidermis, while the eccrine glands were strongly positive, suggesting that careful examination of adnexal structures can be of value.
