Cutaneous manifestations of arsenicisme in Burkina Faso: epidemiological and clinical features

The main aetiology of human arsenic toxicity provide from natural geological source. The characteristic skin lesions of arsenic toxicity may be used as an indicator of high exposure. We have registered 45 cases. The age bracket was one to 70 years. We have registered 27 women (60%) and 18 men (40%). The cutaneous manifestations have been dominated by the palmo plantar hyperkeratosis and hyperpigmentations (77,8% each one). The urinary concentrations of arsenic were 13 microg/l to 212 microg/l; they were 69 to 101 microg/l in the drinking water localized in the golden area, however they were normal outside this area. The clinical features were similar with the description of the literature. Intoxication of drinking water is problem of public health and we recommend checking all the other golden areas to find some appropriate solutions.
