Systemic mastocytosis (SM) is a disorder caused by the abnormal proliferation of mast cells (MCs) in one or more organs, leading to heterogeneous clinical presentations. SM patients are more at risk for hymenoptera-sting-induced anaphylaxis1 and in these patients indolent systemic mastocytosis (ISM) is the most frequent form of this disorder.
