The use of dermoscopy increases clinical ability for differentiating of various types of melanocytic lesions and improves possibility of recognition of melanomas in their earliest stages. Different dermoscopic types of naevi could be recognized based on their structural characteristics, that is, on the quantity and distribution of pigments. Majority of people with multiple nevi have a predominant nevus type. Possible connection between a predominant melanocytic nevus and the age and/or skin phototype would enable easier recognition of dermoscopic patterns of unusual nevi for particular age and/or skin phototypes of patients which would in addition enable early recognition of melanoma. The aim of this research was to determine correlation of dermoscopic patterns, pigment distribution and colour of melanocytic nevi to age and skin phototype of patients. The research included 400 patients of the Clinic of Dermatovenerology in Niš, in the period from 2008 to 2012. A structural pattern was ...determined for each nevus, as well as its pigment distribution and colour. The link between dermoscopic characteristics was analysed in relation to age and skin phototype of patients. There were 6680 acquired melanocytic nevi which were analysed. A globular pattern was the most predominant among the youngest age group, while a reticular pattern showed significantly increased spread among the elderly. Central hyper/hypopigmentation revealed significant differences in frequency depending on skin phototype. Predominant dermoscopic patterns of melanocytic nevi depends on age of patients, whereas colour and pigment distribution depends on skin phototype.
