Correlations of the dermatoscopic index with anthropometric and somatotypological parameters of men with benign nevi

Abstract

Malignant transformation of benign nevi is one of the factors that leads to increased scientific interest in the study of the pathogenesis of their occurrence, the influence of external factors on them, etc. One of the still unsolved issues is the study of the relationship between the features of nevi indicators and the anthropometric parameters of the human body. The purpose of the work is to investigate the peculiarities of correlations of the dermatoscopic index with anthropometric and somatotypological indicators of Ukrainian men with benign nevi. A clinical, laboratory and pathogistological examination of 34 Ukrainian men of first adulthood with melanocytic benign simple nevi, 27 with melanocytic benign dysplastic nevi, 14 with melanocytic benign congenital nevi, and 17 with non-melanocytic benign nevi was carried out. The dermatoscopic index was calculated according to the “ABCD rule of dermatoscopy”. Anthropometric examination was carried out according to Bunak’s scheme. The Heath-Carter mathematical scheme was used to assess the somatotype. Matiegka formulas were used to calculate fat, bone and muscle components of body mass. In addition, the muscle component of body weight was estimated according to the method of the American Institute of Nutrition. The assessment of correlations between the dermatoscopic index and body parameters was carried out in the license package “Statistica 6.0” using the non-parametric method of Spearman. An analysis of multiple reliable and average strength of unreliable correlations between the value of the dermatoscopic index and anthropo-somatotypological indicators in men with benign nevi was performed. In men with simple melanocytic nevi, only moderately strong direct (r = from 0.30 to 0.34), mostly unreliable, correlations with all sizes of the pelvis were established. In men with melanocytic dysplastic nevi, inverse correlations of medium strength, mostly reliable (r = from -0.38 to -0.52) were established with all dimensions of the pelvis and almost all transverse dimensions of the trunk, as well as with almost half of the indicators of the skinfold thickness. In men with melanocytic congenital nevi, direct, mostly unreliable (r = from 0.30 to 0.47) correlations were established with all dimensions of the pelvis, with almost all transverse dimensions of the trunk, with almost half of the girth of the body and indicators of the skinfold thickness and almost all indicators of the component composition of body weight. In men with non-melanocytic nevi, direct, mostly unreliable (r = from 0.30 to 0.47) correlations were established with all transverse dimensions of the trunk and pelvis, most of the total and girth dimensions of the body. Quantitative analysis of reliable and average strength of unreliable correlations between the value of the dermatoscopic index and anthropo-somatotypological indicators was also carried out. The established features of the correlations expand modern ideas about the risk of benign nevi.
