Systemic mastocytosis is a rare, often undiagnosed disease characterized by the proliferation of mast cells in several tissues. The clinical symptoms are related to the mast cell infiltrates, but also to the release of numerous mediators. Malignant mastocytosis is a term that refers to two different entities: aggressive mastocytosis, where the outcome with a myeloproliferative disease, where the latter governs the prognosis. The potential severity of these diseases justifies the development of more intensive therapeutic measures.

Mastocytosis is a term collectively used for a heterogeneous group of disorders characterized by abnormal growth and accumulation of mast cells. Clinical symptoms occur from the release of chemical mediators and the pathologic infiltration of cells. Three major groups of patients with mastocytosis can be distinguished: i) cutaneous mastocytosis, ii) mastocytosis involving the skin and one or more extracutaneous organ(s), and iii) visceral mastocytosis without involvement of the skin. Groups ii) and iii) account for approximately 15-20% of all cases and have been referred to as systemic mastocytosis. Cutaneous mastocytosis typically presents as urticaria pigmentosa or diffuse cutaneous mastocytosis. These patients usually have a benign course. In contrast, systemic mastocytosis is a diffuse hematologic process with an increased risk to develop aggressive disease. In these patients, additional hematologic abnormalities or a second hematologic process, such as a myeloproliferative or myelodysplastic syndrome, or acute leukemia, may develop. Malignant mastocytosis and mast cell leukemia are rare forms of mastocytosis and characterized by uncontrolled and progressive proliferation and infiltration of mast cells in diverse organs. These patients often present without cutaneous lesions and have a very unfavorable prognosis. Because of the immature morphology of the cells it is often difficult to establish the diagnosis in such patients. However, the use of antibodies to mast cell antigens has recently improved the diagnostic efficiency in patients with suspected mast cell disease. No effective therapy for patients with malignant mastocytosis is known, although some patients may benefit from corticosteroid and interferon alpha treatment. The present article gives an overview of current knowledge about the biology, heterogeneity and treatment of human mastocytosis.
