title: Paraproteinaemia in Sézary syndrome.
abstract: We have observed non-myelomatous monoclonal hypergammaglobulinaemia in a 61-year-old man with Sézary syndrome. Similar cases have not been reported before. Sézary cells of patients studied by other investigators were found to be helper T cells. The abundant production of T-lymphocytic stimuli may possibly explain in our case the occurrence of a paraprotein.
