Dermatoscopy is a non-invasive technique that allows to microscopy structures under the surface of the skin that are not visible to the eye. Dermatoscopy has become a powerful additional method of early diagnosis of melanoma, which allows to distinguish the type of neoplasm (pigmented and non-pigmented) and reduce the frequency of unnecessary biopsies.
The dermatoscopy procedure is performed using a hand-held microscope - a dermatoscope equipped with a magnifying lens and light source. This allows examination of skin structures and patterns. Basically, benign lesions tend to show symmetrical dermoscopic margins and colors, whereas malignant lesions have a tendency to show irregular and atypical dermoscopic structures.
During this diagnostic procedure doctor can apply alcohol, gel or water to a skin. Then the device’s lens is hold over the examined skin area. Often it’s necessary to gently touch the skin with the dermatoscope. Doctor can also take a photo of the area. After the procedure doctor may invite patient for futher examination in some months, remove a lesion with biopsy or reassure a patient if their lesion is harmless.
