Prolymphocytic leukaemia of T-cell type: immunological, enzymatic and ultrastructural morphometric characteristics.
A case of prolymphocytic leukaemia with immunological characteristics of T-cell type is reported. Three noteworthy findings can be emphasized: the presence of C3 receptors on the T-prolymphocytes, the study of the acid-phosphatase isoenzymatic pattern, which showed an increased band 3 with absence of band 3b, and the morphometric ultrastructural investigation. Cytochemistry and ultrastructural morphometry may be useful for a more precise characterization of prolymphocytic leukaemia and help to distinguish it from other lymphoproliferative disorders.
