A multicentre study of naevus‐associated melanoma vs. <i>de novo</i> melanoma, tumour thickness and body site differences*

Abstract

Clinicopathological and body site differences between de novo melanoma and NAM support the divergent pathway model of development. These differences were also found in thin melanomas, suggesting that de novo melanomas are different from NAM and their differences are not due to the obliteration of naevus remnants in thicker tumours.
