D22: Melanocytic naevi

D22.6: Melanocytic naevi of upper limb, including shoulder

There are cells in the skin that form a dark pigment. This makes the skin brown, for example, when you spend a long time in the sun. If the pigment cells in the skin change, then a liver spot can develop. Liver spots therefore usually look dark. They can be different sizes or different shapes. Most liver spots do not cause any problems.

Sometimes liver spots are removed, because there is uncertainty about whether the liver spot is benign or malignant. The liver spot you have is benign. This means that the skin around it will not be destroyed and diseased cells will not spread throughout the body.
