Store-and-forward method has contributed for telemedicine as an efficient method to the clinical diagnosis acquisition. Studies in teledermatology demonstrated important outcomes, such as the use of computer systems based in asynchronous method for long-distance diagnosis, categorization, triage, or clinical outcomes agreements. However, for some issues there is no consensus between studies, such as the image parameters or the data that must be submitted to analyze. The aim of this study is propose the development of a web system that establishing patterns to construct web asynchronous system. A prototype was constructed to test a structure (clinical data and images) to obtain clinical diagnosis concordance in teledermatology. The preliminary outcomes showed that rate clinical diagnosis is nearly when we compare face-to-face method (76.6%) and store-and-forward (70.3%). The most effectiveness occurs to some diseases, who present easy clinical diagnosis in traditional consult. We expect that this system could introduce a numerical method, established in statistical data, to construct store-and-forward system.
