Dermoscopy is an in vivo non-invasive method for making the diagnosis of pigmented skin lesions (PSL) more accurate. It links clinical dermatology and dermatopathology by enabling the visualization of morphological features not discernible by naked eye. With training and experience, dermoscopy has been shown to significantly increase the clinical diagnosis of pigmented skin lesions, with a 10-27% improvement in the diagnosis of melanoma compared to that achieved by clinical examination alone. There are many variants of dermoscope, but all of them have the same essential characteristics - they reduce the reflection and stratum corneum becomes translucent, allowing viewing the underlying skin layers - epidermis, dermo-epidermal junction and upper parts of dermis. Digital dermoscopy has many advantages versus non-digital, for example, follow-up of the lesion. Many authors from all over the world by using the “teledermoscopy” associate to perform multi-centre studies for developing the new diagnostic algorithms, as well as for collection of images and computer-aided diagnosis of PSLs. All dermoscopic methods were classified in two groups: first step - algorithm for differentiating melanocytic from nonmelanocytic lesions, and second step - differentiating benign melanocytic lesions from melanoma. Because of their simplicity for using by less experienced physicians, two of them, ABCD rule and 7-point checklist, are mostly used. In the future, dermoscopy will take the prominent place in medical practice due to increase in need of early recognition of melanoma. Acta Medica Medianae 2006;45(2):59-64.
