Can children have systemic mastocytosis?
Systemic mastocytosis (SM) involves extracutaneous organ infiltration, with or without skin involvement. In children, cutaneous forms of disease account for approximately 90 percent of cases. Most affected children develop skin findings in the first year of life, although lesions can be present at birth.
What age do you get mastocytosis?
Mastocytosis has a bimodal distribution, with 55% of cases presenting from birth to 2 years of age, 10% in children younger than 15 years old, and 35% in those over the age of 15.
What is mastocytosis in children?
Learn more. Abstract: Mastocytosis is characterized by an increased number of mast cells with an abnormal growth and accumulation in one or more organs. In most children mastocytosis is limited to the skin (cutaneous mastocytosis) and often transient as compared with that in adults in whom mastocytosis is usually progressive and systemic.
What causes mastocytosis and is there a cure?
The cause is unknown and there is no cure. A child with mastocytosis has an abnormal accumulation of mast cells. This may occur in the skin or almost any tissue in the body. Mast cells are located normally in nearly all tissues in the body, with their concentration in the GI tract, the skin, and the lining of the respiratory system.
What are the criteria for the diagnosis of systemic mastocytosis?
*SM criteria: criteria for establishing the diagnosis of systemic mastocytosis (see Table 2); †AHNMD: associated clonal hematologic illness of an origin other than the mast cell line; ‡reduced organ function: ascites, disturbed liver function and/or portal hypertension (liver), hypersplenism (spleen), malabsorption with hypalbuminemia and loss
What is the mastocytosis network?
The network will also cooperate with authorities in the field of mastocytosis in the US and other non-European countries (International Advisors) in order to establish worldwide standards.
