ABSTRACT
Familial lymphohistiocytosis is a rare rapidly lethal genetic disease It is characterized by an uncontrolled activation of T lymphocytes and macrophages, with multiple organ infiltration, beginning with fever and unexplained coagulopathy. Recently, one of the genes implicated in 50% of families at risk was identified [locus FHL1, chromosome 10, region q21-22]. Based on data suggesting an essential role of T lymphocytes in the genesis of familial lymphohistiocytosis, the treatment has recently evolved from a chemotherapy including Etoposide [VP16] and corticosteroids, sometimes efficient but toxic, to an almost always efficient and slightly toxic immunosuppressive treatment. These two treatments achieved a remission somewhat lasting with no definite cure. In fact, all patients relapsed in the central nervous system and died. Bone marrow transplantation [BMT] is the only curative treatment. However only 20% of patients benefit from an HLA identical BMT. Recent improvements in HLA non-identical BMT offer an acceptable alternative to the other 80% of patients.In this review, we present three cases illustrating the evolution and optimization in the management of infants with familial lymphohistiocytosis
