Systemic Mastocytosis

Systemic mastocytosis is a rare health condition where you have too many mast cells, a type of white blood cell. Mast cells are part of your immune system and, once activated, they release mediators -- such as histamine -- that cause certain immune responses.

With SM, extra mast cells can build up in your tissues and organs and cause an increased immune response. This can lead to symptoms and additional problems (complications).

Learn about SM and how it can affect the body.
