C43.4: Malignant melanoma of scalp and neck

You have melanoma (skin cancer) of the scalp or neck.

The tissue in the body is made up of cells. With cancer, the cells multiply uncontrollably, which leads to a malignant neoplasm (abnormal growth of tissue) developing. The cancer cells can destroy the healthy tissue and spread throughout the body.

Melanin-producing cells in the hirsute part of your scalp or in your neck have multiplied uncontrollably. In the skin, special cells produce a dark pigment. This pigment is to protect the body from sunlight. If a lot of sunlight gets on your skin, then these skin cells produce more pigment. This makes the skin brown. These melanin-producing skin cells also occur in the scalp. There the cells release the pigments to the hair roots. These pigments determine the color of the hair. If these melanin-producing cells multiply uncontrollably, a dark patch can appear on the skin.
