Cytochemical and immunocytochemical studies in some lymphoproliferative disorders

ABSTRACT

This study was carried out on 40 patients with different lymphoproliferative disorers 20 patients with acute lymphoblastic leukemia [ALL], 15 patients with non-Hodgkin's lymphoma [NHL], 3 patients with chronic lymphocytic leukemia [CLL] and 2 patients with multiple myeloma [MM]. The study showed that about 80% of BNHL group express CD10 antigen and that T cells sometimes express it. The 2 cases of MM express CD10 and not CD19 although the latter is a B cell restricted antigen. CD3 is expressed on more mature forms of T- lymphocytes than CD7
