Mast cell activation syndrome. About a clinical case
Abstract
Background: Monoclonal mast cell activation syndrome is included in mast cell activation disorders in which, after a diagnostic process, it is not possible to meet the required criteria for a diagnosis of systemic mastocytosis. Clinical case: A 73-year-old woman who presented two events of anaphylaxis 15 minutes after the intake of yucca; with a positive skin test, elevated tryptase, and mast cells with abnormal phenotype in the bone marrow biopsy, and without criteria for systemic mastocytosis. Conclusions: The diagnosis of monoclonal mast cell activation syndrome requires high clinical suspicion for patients with recurrent anaphylaxis and elevated tryptase, for whom joint management with hematology is essential.
