Summary

Major advances have been made in recent years in the diagnosis and classification of mastocytosis. The WHO classification proposed in 2001 provided well-defined consensus clinical and laboratory criteria for the diagnosis of systemic involvement and the classification of the disease into seven well-defined categories with their prognostic implications. More recently, additional refined criteria and recommendations for the standardization of clinical and laboratory diagnostic tests have been published and new categories of the disease have been further defined; in turn, other variables associated with disease progression and patient survival, such as the pattern of involvement of bone marrow hematopoiesis by the KIT mutation, have been identified. Altogether, these findings indicate that the molecular, histologic, cytologic, and immunophenotypic features of bone marrow mast cells, in combination with the presence of mastocytosis in the skin and/or anaphylaxis and serum baseline tryptase levels, are essential tools in the diagnosis, classification, and prognostic stratification of adult mastocytosis.
