Clinical diagnosis

As a general principle:

Few congenital naevi will become malignant. Those that do, generally do so in adulthood.

For pigmented congenital naevi refer to dermatologist if greater than 1 cm in size or on a cosmetically significant site -

Category 2
to
Category 3   

Most other non-pigmented congenital naevi should not be referred.
