Mast cell activation syndrome

Nature:

Mast cell activation syndrome (MCAS) is a term referring to one of two types of mast cell activation disorder (MCAD); the other type is idiopathic MCAD. MCAS 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. Primary symptoms include cardiovascular, dermatological, gastrointestinal, neurological and respiratory problems.

MCAS is an umbrella term that describes a set of symptoms; it is not a specific diagnosis. Multiple diagnostic schemes for MCAS have been proposed. MCAS has been increasingly over-diagnosed or misdiagnosed.
