What is Systemic Mastocytosis?
A disease of the mast cells that can be found in the skin, internal organs (liver, spleen, GI tract, lymph nodes), and bone marrow. Mast cells can release various chemicals into the body that can produce symptoms of a serious allergic reaction. When these substances cause organ damage, these types of symptoms are known as “C findings,” and include low blood cell counts such as anemia (low red blood cells) or thrombocytopenia (low platelets), liver problems, weight loss, swelling in abdomen, and bone lesions.
Mastocytosis is a very rare condition that is most commonly caused by a mutation in a protein called “KIT” that causes mast cells to grow and divide. There are various subtypes of mastocytosis, which can vary at diagnosis and throughout treatment.
