DO ALL MELANOMAS COME FROM “MOLES”? A STUDY OF THE HISTOLOGICAL ASSOCIATION BETWEEN MELANOCYTIC NAEVI AND MELANOMA

Histological examination of 1101 melanomas (990 superficial spreading and HI nodular melanomas) from 1098 people revealed that 23.3% showed an associated melanocytic naevus. Of these, 56.5% were classified histologically as common acquired, 37.7% as dysplastic and 5.8% as congenital. Of the superficial spreading melanomas, 25.7% showed an associated naevus. By contrast, only 2.7% of nodular melanomas showed histological evidence of a coexisting naevus.
