Q82: Other congenital malformations of skin
Q82.2: Mastocytosis
Mast cells are white blood cells found in various organs and tissues of the body, where they release certain substances known as mediators to fight off pathogens and foreign substances.
Your mast cells are releasing too many mediators. These mediators can also trigger allergic reactions, for example. With an allergy, the immune system overreacts to certain substances. Such substances may be harmless substances in the environment, drugs or certain chemicals, for example.
This mast cell disorder can cause red patches on the skin, for example. The skin suddenly becomes red, swells up and itches. Other organs are sometimes also affected. Abdominal pain and diarrhea may also occur, for example. Pain in the bones and muscles is another possible symptom. You may occasionally have a headache or feel weak.
