Mastocytosis 
(Mast Cell Disorder)

 

What is mastocytosis?

A mast cell is a type of white blood cell that’s found in connective tissue of your body. If your body is producing too many mast cells, it would be diagnosed as mastocytosis. This is a rare condition.

What causes mastocytosis?

Mast cell disease is typically not an inherited condition. It is caused by a mutation in the KIT gene. This is not a condition that be prevented, but you can take action to stop triggers from activating it. It will be important to speak with an allergist to determine the exact reason for your condition, but any of the following could be triggers for your mastocytosis:

  • Physical activity
  • Stress
  • Certain medications
  • Insect bites
  • Pressure or friction on your skin
  • Alcohol

What are symptoms of mastocytosis?

The mastocytosis symptoms depend on the organ of the body that the mast cell disease grows in. The symptoms will also vary based on whether it’s acute or severe mastocytosis. Any of the following symptoms may be present:

  • Skin blisters or hives
  • Nausea or vomiting
  • Diarrhea
  • Swollen lymph nodes
  • Changes in mood
  • Flushing 
  • Lightheadedness

How is mastocytosis diagnosed?

The process to diagnose mastocytosis will start with a discussion of your health history with an allergist. From there, the allergist may recommend blood or skin testing. It’s possible that bone marrow, skin or organ biopsy may be needed to provide the most concise diagnosis.

How is mastocytosis treated?

An important treatment for mastocytosis is controlling the triggers. Certain medications can also help to keep the mast cells from being overstimulated. Depending on the specific type of mastocytosis, additional therapies may be an option.
