Brigham and Women’s Mastocytosis Center

The Mastocytosis Center at Brigham and Women’s Hospital has been providing care for adults and children with mast cell activation disorders for over 20 years. It is one of a select group of academic centers to care for patients with mastocytosis and mast cell activation syndromes. In addition to clinical care, it is an active site for research. Ongoing research includes basic investigations into the biology of human mast cells at the DNA, RNA and protein level, translational research in mast cell activation disorders, and clinical trials with new therapeutic options, including monoclonal antibodies and biological agents.

How We Can Help

The Mastocytosis Center provides care for adults and children with mast cell activation disorders. This includes cutaneous mastocytosis, systemic mastocytosis, mast cell activation syndromes, idiopathic anaphylaxis, and hereditary alpha tryptasemia.

The Center is a multi-specialty group and includes physicians from: Allergy and Clinical Immunology, Gastroenterology, Dermatology, Neurology, Oncology/Hematology, Endocrinology, Pulmonology and Pathology. Our physicians actively collaborate with outside institutions including Boston Children’s Hospital, the National Institute of Health, the European Competence Network on Mastocytosis, and the American Initiative in Mast Cell Diseases.

What Sets Us Apart

  • The BWH Mastocytosis Center is the largest center for mast cell disease in the United States. The BWH Center treats more than 300 patients annually in the Allergy and Clinical Immunology Division alone.
  • Our physicians are internationally recognized experts and were involved in developing diagnostic criteria for mast cell disorders.
  • We are able to care for complex patients through our extensive care team consisting of more than ten physicians in eight different medical specialties.
  • We have developed treatment innovations such as the first ultra-rush venom desensitization protocol for patients with mastocytosis and life-threatening anaphylaxis to hymenoptera venom.
  • Patients seen at the Mastocytosis Center are eligible to participate in ongoing clinical and/or translational research. Our database contains over 1500 patients, including 1000 patients with systemic and/or cutaneous mastocytosis and 500 patients with mast cell activation syndromes.
