Due to the increase in the incidence of malignant neoplasms of the skin, their early diagnosis by optical methods becomes more relevant. Therefore, for a good dermatologist it is necessary to be familiar to them. In addition to that, modern technology allows specialists to diagnose patients faster and more accurately. It makes it easier for doctors to diagnose more patients with high accuracy and saves lives of a lot of patients, as diagnostics become less expensive and much more affordable for people who are struggling with their finances. Some skin diseases, melanoma for example, are extremely dangerous, so it is very important to expose them as quickly as possible. There are multiple optical methods that are commonly used by dermatologists. At the current moment dermatoscopy remains the key routine diagnostic method in the practice of a dermatologist. The most promising method is the combination of optical diagnostics and artificial intelligence. The method of digital photometry makes it possible to visualize the smallest pathological elements of human skin. Video Dermatoscopy in combination with artificial intelligence serves as a way to identify or exclude a diagnosis based on the input of received results and doctors predictions. Confocal laser optical scanning microscopy is a non-invasive method of observing the upper layers of the epidermis. All of these methods may be used depending on different occasions, making optical methods quite versatile. This presentation was made to describe the optical methods used in dermatology to everyone, who will be diagnosing any malignant neoplasms of the skin.
