This article reports on a study to evaluate efficacy and reliability of asynchronous teledermatology for diagnosis of skin diseases. Fifty patients with dermatologic disorders were seen in a poor tropical rural zone, first by non-dermatologists in conventional consultation and then by dermatologists to obtain a diagnosis (gold standard). The latter step consisted of evaluation of filmed lesions by another group of dermatologist later on. Results: there was a high concordance of diagnosis between the two groups of dermatologists when kappa analysis was performed. Conclusion: it appears important to use these technological advances in developing-countries to improve delivery of health care
