A blue nevus is usually raised and looks like a dome. It can be dark blue to almost black in colour.
Occasionally, a melanoma may look very similar to this type of mole (See photograph).
There are many places on the body where blue nevi can develop; however, they are usually isolated. This means you are unlikely to see more than one nevus in one area. The most common places on the body for blue nevi to occur is the face, neck, hands, feet, scalp and buttocks.
Blue nevi typically exhibit the following characteristics:
- An oval or round shape
- Small in size
- Appearance: smooth
- a flat or elevated surface
- a diameter of around 1-5 mm
A blue nevus should be positively identified every time by your doctor to confirm that it’s not a melanoma.
