In agreement with other studies, autoantibodies in the lack of clinical manifestations have been frequently observed in our vitiligo patients, especially during the early phase of the disease. The clinical significance of this finding seems to be limited, with the possible exception of thyroid disease, and it needs further exploration, through large cohort studies.

The epidemiological data of the skin conditions considered in the present study can be considered roughly in agreement with those reported in the available surveys. Because they were obtained in a large sample of Italian young males from the general population, they can be useful for therapeutic and preventive interventions by the public health organizations.
