[Frequency of viral infections (especially with herpes virus) during Darier's and Hailey-Hailey's diseases (author's transl)].

The fragility of epidermal cells in Hailey-Hailey's disease end even more in Darier's disease seems to favour the development of viral infections. The authors present six cases of herpes virus infections in three siblings with an intermediate form between Darier's disease and Hailey-Hailey's disease, both having a tendency to recur. One of the flares demonstrated signs of Kaposi and Juliusberg's pustulosis vacciniformis which is often found in the literature as a complication of Darier's disease. The authors discuss the frequency of the recurrences, which could be due to different viruses. Herpetic virus is often found, less frequently vaccinial virus, but sometimes also Coxsackie A 16 virus.
