The International Mastocytosis & Mast Cell Diseases Awareness Day website is an online global platform uniting Mastocytosis and Mast Cell Disease patients, caregivers and health care practitioners from around the world.

Our goal is to foster a unified and multi-lingual channel of information from participating non-profit worldwide Mastocytosis support and/or affiliated advocacy groups.

The first annual awareness day took place on 20 October 2018 and will take place on October 20 each year thereafter. We welcome and encourage all nations to join in our efforts with sharing Education, Awareness and Support tools that aid researchers and scientists to find a cure for Mastocytosis and Mast Cell Diseases.

Our logo was intentionally crafted to include both “mastocytosis” and “mast cell diseases” in the same size font, for equal representation. The mast cell icon depicted has “receptors” and seems to be spilling its contents during degranulation. The color purple was chosen to represent the color of the stain that researchers use in their slides.

The ribbon has dots to represent the spots/hives/rashes that many mast cell patients deal with.
