Platelet satellitism is believed to be an in vitro phenomenon induced at room temperature in ethylenediamine tetraacetic acid–anticoagulated blood. Most reports involve neutrophils; involvement with circulating lymphoma cells are exceedingly rare. Normally, mature B cells exhibit allelic exclusion in which a single class of surface immunoglobulin light chains (either κ or λ ) is expressed. The simultaneous expression of both κ and λ immunoglobulin light chains is rare. Herein, we report the unusual case of a patient with splenic marginal zone lymphoma in which circulating lymphoma cells express dual surface immunoglobulin light chains and exhibit platelet satellitism. In addition to clinical findings, a comprehensive analysis of the peripheral blood including correlated light and electron microscopy as well as flow cytometry are described.
