[Changes in immunologic phenotype of cells in hairy cell leukemia]. / Izmenenie immunologicheskogo fenotipa kletok pri volosatokletochnom leikoze.

ABSTRACT

A case of hairy-cell leukemia (HCL) has been described in which the cells of the pathological clone in the course of time lost their surface immunoglobulins and retained membrane markers associated with the T-lymphoid series. It has been suggested that this change in the immunological phenotype of the cells may lead to an erroneous diagnosis of T-cell HCL.
