Best Answer

Mast cell activation syndrome (MCAS) is one type of mast cell activation disorder (MCAD), and is an immunological condition in which mast cells inappropriately and excessively release chemical mediators, resulting in a range of chronic symptoms, sometimes including anaphylaxis or near-anaphylaxis attacks.

What is mast cell disease?

Systemic Mastocytosis is a disorder where mast cells are abnormally increased in multiple organs including the bone marrow. Mast cells are immune cells that produce a variety of mediators, such as histamine, that are important in the body's allergic responses. The disease can occur in both children and in adults.

What drug is a mast cell stabilizer?

Mast cell stabilizers are chromone medications used to prevent or control certain allergic disorders. They block mast cell degranulation, stabilizing the cell and thereby preventing the release of histamine and related mediators. One suspected pharmacodynamic mechanism is the blocking of IgE-regulated calcium channels.

Is mast cell tumor cancer?

Mast cell tumor (MCT) represents a cancer of a type of blood cell normally involved in the body's response to allergens and inflammation. MCT is the most common skin tumor in dogs; it can also affect other areas of the body, including the spleen, liver, gastrointestinal tract, and bone marrow.
