Abstract
The high incidence of melanoma and unsatisfactory results of its treatment in some cases make the issue of timely diagnostics of pre-melanoma skin pathology, in particular the identification of pre-melanoma pigmented nevi, of great importance and can be used for choice an adequate tactics of treatment. The purpose of the study was to evaluate the informativeness of dermatoscopy in cases of patients with pigmented nevi of skin as a part of melanoma prevention. 168 patients with pigmented nevi were screened. All nevi were photographed with a digital camera SONY Cyber-Shot DSC-H3, first in normal mode with the capture of the localization zone of the tumor and its surrounding tissues, and then in macro mode (“Zoom 10”). To confirm the clinical diagnosis, additional characteristics of the pigment formation on the skin, the manual immersion dermatoscopy, was used using the contact non-polarized HEINE mini 3000 LED dermatoscope. Evaluation of images was carried out using the diagnostic algorithm ABCD and ABCD-E. Our findings suggest that the clinical diagnostic algorithm used by us for detecting signs of the activation of a pigmented nevi is highly informative — the sensitivity is 97.6 %. Performing immersion dermatoscopy allows to increase the informativeness of the clinical and instrumental examination at the preoperative stage up to 98.2 %, which is comparable with the data obtained at the stage of urgent cytological examination: the method sensitivityis 98.2 %.
