Cases of rare congenital forms of
aplastic anaemia
are presented. Fanconi anaemia is most frequently diagnosed, while
reticular dysgenesis
, amegakaryocytic thrombocytopenia and dyskeratosis congenita occur exceptionally rarely. A presumably new entity of congenital
aplastic anaemia
called "RAC" syndrome (retinopathy--
aplastic anaemia
--central nervous system abnormalities) is presented too. A short summary of the pathomechanism of congenital aplastic anaemias and present therapeutic attempts, including the possible therapeutic use of the newly discovered stem cell factor are described.

Fulminant hepatic failure of unknown origin is the most common cause of fulminant hepatitis with high incidence of
aplastic anaemia
. Furthermore, the association of liver failure and
aplastic anaemia
has an increased mortality rate. In this report we describe a 16-month-old boy who presented with
aplastic anaemia
preceding a non-A, non-B, non-C fulminant liver failure. He developed severe graft versus host disease (GvHD) after liver transplantation, proven by the presence of donor cells in the peripheral blood and in the skin biopsy. He received conventional therapy (steroids, mycophenolate, anti-IL-2 monoclonal antibodies, anti-thymocyte globulin) without success. In an attempt to obtain T cell depletion and reduce the GvHD, he was treated with Alemtuzumab, a first time use for this indication.
Aplastic anaemia
was extensively investigated, especially exploring the possibility of primary immunodeficiency and
reticular dysgenesis
which were excluded based on clinical history. However, another form of primary immunodeficiency could be the cause of the uncontrollable proliferation of the donor lymphocytes derived from the liver transplant. Despite aggressive treatment GvHD progressed and the patient died of multiorgan failure. The majority of authors mention
aplastic anaemia
as a secondary event post liver transplant, whereas in our view this might be a haematopoietic stem cell disorder preceding fulminant hepatic failure. These patients also need to be evaluated extensively in order to exclude a primary immunodeficiency. The underlying disease will determine the choice of immunosuppressive treatment, especially in case of development of GvHD caused by the transplanted lymphocytes inhabiting the donor liver.
