title: Autoimmune lymphoproliferative syndrome (ALPS). Case report and family history.
abstract: Autoimmune lymphoproliferative syndrome (ALPS) is a rare disease caused by defective lymphocyte apoptosis and is characterized by non-malignant lymphoproliferation, hepatosplenomegaly, autoimmune manifestations and increased risk of both Hodgkin's and non-Hodgkin's lymphoma. Most forms of the disease are due to germ line mutations of the FAS gene and manifest during the first years of life with fluctuating lymphadenopathies, hemolysis, immune thrombocytopenia. During the second decade of life disease manifestations improve spontaneously but autoimmune problems still occur and there is an increased risk of lymphoproliferative malignancy. We describe a typical case of ALPS in a now 44 year old man, followed since the age of 2 for disease manifestations that were unclear at the beginning.
