Distribution of atypical (dysplastic) melanocytic nevi (AMN) diagnosed between 1989 and 1998 at St Bartholomew's and the London National Health System Trust, London, England. The highest incidence was observed between 1993 and 1996 following the advent of the consensus on diagnostic criteria of AMN (published in 1991). The decreased incidence in 1997 and 1998 correlated with an increased rate of melanoma in situ.
