Leukaemic reticuloendotheliosis: A morphological and immunological study of four cases

Abstract

Morphological and immunological studies of four cases of leukaemic reticuloendotheliosis are reported. The findings indicate that leukaemic reticuloendotheliosis is a monoclonal B cell neoplasm in which the leukaemic cell expresses either Kappa or lambda light chain and delta heavy chain determinants. The similarity between this disease and chronic lymphocytic leukaemia is discussed.
