What is mastocytosis? Mastocytosis (say mass-toe-sigh-toe-sis) is the abnormal growth of mast cells in the body. Mast cells are part of the immune system, which helps protect your body against infection. The most common form of mastocytosis is when mast cells accumulate on the skin, causing reddish-brown spots or bumps.
Systemic mastocytosis (mas-to-sy-TOE-sis) is a rare disorder caused by a mutation that results in an excessive number of mast cells in your body. Mast cells normally help protect you from disease and aid in wound healing. But if you have systemic mastocytosis, excess mast cells can build up in various parts of your body. When triggered, these mast cells release substances that can overwhelm your body. You might experience symptoms such as facial flushing, itching, a rapid heartbeat, abdominal cramps, lightheadedness or even loss of consciousness. Common triggers include alcohol, temperature changes, spicy foods and certain medications.
