Objective To determine the demographic, epidemiological and clinical features and associations of different types of nevi from eastern India. Methods This descriptive study was carried out R. G. Kar Medical College and Hospital, Kolkata over 12 months (from March 2013 to February 2014). Two hundred patients of all age groups and both sexes presenting with or found to have nevi were evaluated for demographical, clinical variables and comorbidities.  Results The most common type of nevus in our study was Becker’s nevi and the least common was eccrine angiomatous nevus. Most common age of presentation was the first and second decades. An overall female preponderance was noted in our study. Infantile hemangioma was seen more commonly in girl children. Nevus of Ota was commoner in females. In contrast to previous findings, majority of VEN lesions were on head and neck region, followed by trunk. Most of the lesions of ILVEN affected lower half of the body. Conclusion A diverse variety of nevi were seen, more commonly in females. They usually appear in the first and second decade of life. Patients should be meticulously examined for cutaneous and systemic associations.
