The Authors compare the results of epicutaneous tests which were carried out on 23 patients affected by a familial benignant chronic pemphigus (FBCP) and on 150 patients of the control group with dermovenereologic pathologies in order to evaluate whether allergic contact dermatitis (ACD) is more frequent in patients suffering from Hailey-Hailey condition (HH) which is treated with topical drugs. A set of standard allergens and some of the substances which are used in topical dermatological therapy were tested separately. Two patients suffering from FBCP (8.7%), vs 11 patients of the control group (7.3%), showed a good response to the former (sulphate nickel and potassium dichromate). Only one patient suffering from FBCP (4.3%) had ACD, when undergoing topical treatment, as a reaction to sulphate neomycin and sulphate gentamicin vs 3 patients of the control group (5%). In conclusion, there is not an increased sensitization in patients suffering from HH.
