Abstract
The method of diagnosis of pigmented skin tumors using spectrophotometric analysis (SPM) of dermatoscopic images was analyzed in the article. The obtained results indicate the possibility of using SPM as an addition to the standard methods of dermatoscopic diagnostics to make the correct diagnosis that is confirmed by clinical examples and are histologically proven.
Highlights
Differential diagnosis of the most atypical melanocytic lesions is extremely complex
There is a large range of non-melanoma tumors that are similar in color with melanoma venous hemangioma, pigmented basalioma and dyskeratosis
62 dermatoscopic images of pigmented skin tumors were characterized by the rule of ABCD which included assessment of symmetry, contours, colors, and tumor diameter with general diagnostic index (GDI) determination
Summary
Differential diagnosis of the most atypical melanocytic lesions is extremely complex. There was noted the fact that superficial melanomas arise on the background of premelanoma nevi and it is important to establish the differences between these lesions. Often neither clinical nor dermatoscopic signs give a clear differential diagnosis. Despite the use of a general diagnostic index (GDI) dermatoscopic diagnosis is subjective and its accuracy in the diagnosis of melanoma is 7584 % [25]. This requires the additional criteria for dermatoscopic diagnosis of pigmented skin lesions. The aim of the study was to develop spectrophotometric criteria of differential diagnosis of pigmented skin lesions based on the analysis of digital dermatoscopic images
