Aggressive systemic mastocytosis


Systemic mastocytosis, often termed systemic mast cell disease (SMCD), is a clonal disorder of the mast cell and its precursor cells. The clinical symptoms and signs of systemic mastocytosis (systemic mast cell disease) are due to the accumulation of these clonally derived mast cells in different tissues, including bone marrow, skin, the gastrointestinal (GI) tract, the liver, and the spleen


Systemic Mast Cell Disease Systemic Mastocytosis Urticaria pigmentosa Organ failure Enlarged liver Enlarged spleen Enlarged lymph nodes Impaired liver function


Some studies have shown that mutations of the c-kit proto-oncogene may cause some forms of mastocytosis (mast cell disease).Mutations of c-kit in mast cell tumor lines and the ability of c-kit to cause mast cell proliferation and transformation suggest that these mutations are necessary in some forms of mastocytosis. Several types of mutations in c-kit have been demonstrated to cause mastocytosis
