How common is systemic mastocytosis in bone marrow?

Systemic mastocytosis is quite rare overall. Mast cell leukemia (MCL), which is the most aggressive form of systemic mastocytosis, accounts for less than 1 percent of all mastocytosis cases.

When systemic mastocytosis does occur, it affects the bone marrow along with other organs throughout the body. About 7 percent of children and 30 percent of adults with systemic mastocytosis may eventually develop mast cell leukemia or mast cell sarcoma.

For diagnosis, doctors look at bone marrow samples. A person is diagnosed with mast cell leukemia specifically if at least 20 percent of their bone marrow cells are mast cells, or if more than 10 percent of blood cells are mast cells.

While systemic mastocytosis is uncommon, it's important to work closely with your healthcare team if you're experiencing symptoms or have concerns about mast cell disorders.
