Dermatoscopy is an imaging technique that allows the visualization of skin lesions on a large scale; studies and analyzes the structure and patterns of pigmented lesions, such as melanocytic nevus or moles, as well as other non-pigmented tumor lesions.
With digital dermoscopy , a mapping of the skin is recorded, recording photographs of the entire body that will be archived so as to see, in subsequent visits, whether new nevus has appeared or if the ones already presented by the patient have increased in size. Subsequently, certain lesions are selected to record their dermatoscopic images, a fact that allows dermatologists , on the one hand, to analyze the structure of the same and, on the other hand, to compare possible changes in successive visits.
Digital Dermoscopy Technique
The patient is examined the entire skin surface by analyzing with a dermatoscope the pigmented lesions and selecting those that are more atypical. Subsequently proceed to take panoramic clinical photographs of the different parts of his body, and then record the dermatoscopic images of previously selected nevus. All files are saved for future comparative studies.
Improvements that digital dermatoscopy has contributed to Dermatology
Digital dermatoscopy has led to a revolution in Dermatology, as it not only allows us to track melanocytic or nevus lesions objectifying the changes, but also provides a lot of information that helps us to differentiate if a melanocytic lesion is benign or malignant.
Margin of error of the digital dermoscopy
The margin of error only depends on the scanner that analyzes the images; the greater experience and training of the dermatologist in digital dermatoscopy better diagnostic accuracy will achieve
