New acquisition about mole typologies:clinical arrangement and phenotypic correlation

Till now, moles’ study has not examined closely clinic-phenotypic subject to estabilish a correspondence bet ween phenotype and nevus morphology. The aim of our study is working out a classification of nevus in typologies, to value their argement in a randomised sample. Material and methods: In the Dermatological Clinic, University of Study Federico II of naples, through a form, skilled workers gathered information about 183 patients. According to literature (Ackermann, Saurat), nevi have been classified on the basis of clinic-morphologic features. Data have been analysed by the statistic analysis programme, SPSS 8.0. Results: The most frequent typology is the little brown nevus, specially in females. Trunk is the favourite place of mole arrangement. Besides, little nevi characterize limbs and III and IV phototypes; bright phototype people has a poor number of nevi, mainly the big brown one. More often people presents two or three typologies at the same time. 20-30 years old people has mainly 3 joined typologies, while the 35.5% of the older ones presents only 1 tipology, mainly the little brown nevus. Conclusion: This pilot study can give the way a larger one let to attribute to everyone flexible and well codified classes of analysis, to bearing clinical nevi examination. To estabilish the fittest personal follow-up, according to phenotype and typologies, can help to catch early and to be careful to some atypical nevi. According to risk factors, it can start biomolecular studies about phenotype and mole classes correspondence.
