Cytochemical profile of B and T leukaemic lymphocytes with special reference to acute lymphoblastic leukaemia. 1974

D Catovsky, and J Galetto, and A Okos, and E Miliani, and D A Galton

The PAS and acid phosphatase reactions showed a different pattern of positivity in the cells of lymphoproliferative disorders according to their B or T cell nature. In B-cell leukaemias (chronic lymphocytic and prolymphocytic) a low proportion of lymphocytes gave a positive result with the acid phosphatase reaction, while the majority were PAS positive in granular form. In contrast, in the T-prolymphocytic and T-lymphoblastic leukaemias the acid phosphatase reaction was positive in the majority of cells, while the PAS reaction was only positive in a minority. The significance of these findings, particularly for the recognition of a distinct T-cell variant of acute lymphoblastic leukaemia, is discussed.
