HOZ, B. de la et al. Guidelines for the diagnosis, treatment and management of mastocytosis. Anales Sis San Navarra [online]. 2008, vol.31, n.1, pp.11-32. ISSN 1137-6627.

Mastocytosis consists of a group of disorders characterized by a pathologicincrease in mast cells in tissues including skin, bone marrow, liver, spleen, andlymph nodes. Mastocytosis is a rare disease and general practitioners have limited exposure to its clinical manifestations, diagnosis, classification, and management. Moreover a complete and clear review in this field is not easy founded. Diagnosis of mastocytosis is suspected on clinical grounds and is established by histopathologic examination of involved tissues such as skin and bone marrow. The most common clinical sign of mastocytosis is the presence of typical skin lesions of urticaria pigmentosa. Most patients experience symptoms related to mast cell mediator release, and prevention of the effects of these mediators on tissues constitutes the major therapeutic goal in the management of mastocytosis. Despite recent advances in knowledge about the pathophysiology, diagnosis, and classification of mastocytosis, a curative treatment for mastocytosis does not now exist; furthermore mastocytosis is a chronic diseases with different severity grades but in all of them with an important negative impact on quality of live of patients. Management of patients within all categories of mastocytosis includes: 1. A careful counselling of patients (parents in paediatric cases) and care providers. 2. Avoidance of factors triggering acute mediator release. 3. Treatment of acute mast cell mediator release. 4. Treatment of chronic mast cell mediator release, and if indicated. 5. An attempt to treat organ infiltration by mast cells. The goal of this review is to provide a practical guide focus on diagnostic criteria for the different treatment options currently available and their management.
