These acquired moles consist of nests of naevus cells both at the
dermoepidermal junction and in the dermis so they are raised. There are
only two colours (light and dark brown) present in these benign naevi. |

This sun-damaged lady had previously had a melanoma removed but this
lesion is benign. There are essentially only two shades of pigment
present dispersed in an organised and regular manner.
|
 |
It is sometimes useful to examine these lesions from a distance because
the regularity of organisation of pigment and outline is more reassuring
than the minor variations seen on very close inspection which may cause unnecessary
alarm.
|
 |
It is helpful to contrast these benign naevi with the heavily and
variously pigmented melanomas depicted elsewhere in this section.

This is the same patient as in the image above. All Caucasians have multiple
moles and they vary in appearance even in one individual.
