Abstract
BACKGROUND: An increase in the frequency of registration of skin malformations, benign, precancerous and malignant skin neoplasms requires new approaches to their diagnosis and treatment. The different depth of melanocytic nevi in the epidermis and dermis is reflected in the color of the melanocytic nevus.
AIM: to study the localization, size and intensity of pigmentation of melanocytic nevi depending on their color.
MATERIALS AND METHODS: A clinical and instrumental study of 280 people with melanocytic nevi of various localization was conducted using their colorimetric assessment and dermatoscopic diagnosis. If melanoma was suspected, patients were consulted by an oncologist. The diagnosis of "melanoma" was confirmed histologically.
RESULTS: Melanocytic nevi are more localized on the face than on the abdomen, back or chest, which is confirmed statistically. The largest sizes ― 5.5 mm ― are reached by nevi having a dark brown color, and, consequently, localized in the epidermis above the basal layer, and the smallest ― 2.0 mm ― melanocytic nevi with brown color located in the basal layer of the epidermis, which is also statistically confirmed.
CONCLUSION: The largest sizes ― 5.5 mm ― are reached by nevi having a dark brown color, and, consequently, localized in the epidermis above the basal layer, and the smallest ― 2.0 mm ― melanocytic nevi with brown color located in the basal layer of the epidermis.
