Definition of mastic. 1 : an aromatic resinous exudate from mastic trees used chiefly in varnishes.
1 MCAS-synonym: mast cell activation disorder (MCAD) - is characterised by the accumulation of genetically altered mast cells and/or abnormal release of mast cell mediators, affecting functions in potentially every organ system, particularly the skin, gastrointestinal tract, and cardiovascular and nervous systems. In systemic mastocytosis with associated haematological non-mast cell lineage disease (SM-AHNMD), the prognosis depends on the course of the associated haematological disorder. 2  Agressive systemic mastocytosis and mast cell leukaemia have a poorer prognosis.
