Melanocytic naevi are pigmented moles. \u201cMelanocytic\u201d means that they are made up of melanocytes, cells that produce the dark pigment, melanin, that gives skin its color. Melanocytes clustered together to form naevi. Melanocytic naevi can be found anywhere on the skin. Melanocytic naevi that are present at birth or developed within the first two years are called congenital melanocytic naevi. Giant congenital naevi that are larger than 20 cm in diameter have a greater risk for developing melanoma, which is cancerous. Melanocytic naevi that develop during childhood and early adult life are called acquired melanocytic naevi. Dysplastic or atypical naevi is less common and have an increased chance to develop into melanoma.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

      • Moles can develop anywhere on the body including scalp, armpits, under the nails, between the fingers and toes.
        Most people have 10 to 40 moles, usually asymptomatic and benign<\/li>
      • Hormonal changes of adolescence and pregnancy may cause moles to become larger and darker<\/li>
      • Moles are usually less than 6 mm in diameter. Rarely, congenital nevi can be over 20 cm in diameter are called giant congenital melanocytic nevi. In rare cases melanoma may develop in this type of giant mole<\/li>
      • Atypical or dysplastic nevi are not common and have darker center and lighter, irregular borders and > 6mm in diameter. Although benign, they exhibit some clinical and histologic features of malignant melanoma so warrants close surveillance<\/li>
      • Person having 5 or more atypical naevi, or more than 50 melanocytic naevi have 6 times higher risk to develop melanoma<\/li><\/ul>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t
