Learn more about Mastocytosis

Content updated on Sep 20, 2022

What is mastocytosis?

Mastocytosis occurs when there are excessive numbers of mast cells (part of the immune system) in the body. This can affect the skin or other parts of the body. It's generally due to a non-inherited genetic mutation, and affects both sexes equally. Triggers of mastocytosis attacks include friction on the skin, physical activity, insect bites, stress, alcohol, certain food and medications.

Symptoms of mastocytosis

  • Black/blue/brown spots or moles, on the skin and lining of the mouth

  • Welts appear when skin is scratched or rubbed

  • Redness in sun-exposed areas of skin

Questions your doctor may ask to check for mastocytosis

Your doctor may ask these questions to diagnose mastocytosis

  • Are there black, blue, or brown spots on the skin or elsewhere? (Including moles)

  • Is your skin red in places where it is exposed to friction or irritation?

  • Do you have redness on the sun-exposed areas of your skin?

Treatment for mastocytosis

People with mastocytosis should reduce exposure to triggers. Treatment includes medications to reduce symptoms or ultraviolet light therapy. Since there's an increased risk of a severe allergic reaction (anaphylactic shock), they should carry an EpiPen (injectable epinephrine).
