What is Mastocytosis?

  • Mastocytosis: A disorder where excessive amounts of mast cells proliferate in organs such as the skin, liver, bone, spleen and gastrointestinal tract. Mast cells occur in connective tissue and defend the body against disease by releasing histamine to stimulate the immune system.
  • Mastocytosis: A heterogeneous group of disorders characterized by the abnormal growth and accumulation of mast cells in one or more organ systems. Recent data suggest that most variants of mastocytosis are clonal disorders. (WHO, 2001) -- 2003
