[Familial Wilson's disease: copper induced hemolysis, hypersplenism and hyperpigmentation as the main symptoms].

Wilson's disease was diagnosed in a 16-year-old adolescent who presented with signs of hypersplenism due to cirrhosis, with marked hyperpigmentation of both lower legs and neurological disturbances. In view of progressive thrombocytopenia and leukocytopenia, splenectomy was performed during therapy with penicillamine later in the course, and the result was good. The patient's 12-year-old sister was found to have a hepatic form of Wilson's disease with typical biochemical findings. During the initial hospitalization a severe, spontaneous copper-induced hemolysis was noted. Another sister probably has a presymptomatic form of the disease. The parents are healthy but heterozygote carriers with regard to biochemical findings. The importance is stressed of hypersplenism, hyperpigmentation of the legs and especially of acute hemolysis in infancy as pointers in the diagnosis of Wilson's disease. Further diagnostic and therapeutic aspects are discussed.
