Let’s look new or changing moles from the skin doctor.



What is a dysplastic naevus to recognize ?

It is the “A B C D E rule”:

A stands for asymmetry. Benign moles are roughly round and symmetrical. Irregular configurations are suspicious.

B is limiting. This should be sharp. Blurred Edges foothills in an otherwise sharply defined birthmark are suspicious.

C stands for Engl. Color (color). Benign moles usually contain only a single color. Several shades of brown, dark brown or blackish shares in lighter birthmarks and especially whitish or reddish shares are suspicious.

D is for diameter: Suspicious moles are greater than 5 mm. However, malignant transformations come before on smaller moles.

E stands for grandeur. Palpable , raised parts in otherwise smooth birthmarks are, especially if these shares are blackish or reddish or even wet or bleeding, suspicious.


You may have to remove more suspicious moles.

Avoid, as far as possible, intense tanning. Especially sunburn must be avoided. Once or twice annual inspections of all birthmarks are recommended by the dermatologist. Between examinations once a month you should look at your moles and check for yourself the ABCDE rule. Suspicious moles are stored digitally or photographed and measured in order to detect changes. If a mole change between the examinations, you can examine this expertly .

During pregnancy, moles are often darker. On the other hand, hormonal changes occur during this phase increased from malignant transformation of birthmarks. Here especially careful and frequent checks are therefore required.
