title: [Mastocytosis--a review illustrated by two case reports].
abstract: BACKGROUND
  Mastocytosis includes a range of disorders characterised by accumulation of tissue mast cells. These are derived from pluripotent haematopoietic stem cells. Recent research has improved the understanding of the mastocytosis pathogenesis. Organ manifestations and symptoms are highly variable.
  
  
  METHODS
  Two cases of systemic mast cell disease are presented.
  
  
  RESULTS
  One patient had urticaria pigmentosa and systemic mast cell disease; the other had systemic mast cell disease and myelodysplastic changes in the bone marrow.
  
  
  CONCLUSIONS
  The two cases illustrate different manifestations and different prognosis for various types of mastocytosis.
