Second, unusual expression of surface antigens in ANKL cells was a prominent feature. Accessed April 2011. As the number of abnormal cells increases in the bone marrow, they may crowd out and inhibit the production of normal white blood cells, red blood cells, and platelets, and eventually abnormal cells may also be released into the blood.

Additional FISH or molecular testing may be recommended by the Mayo pathologist to facilitate diagnosis. Am J Clin Pathol. Immunophenotypic abnormalities of different B-NHL subtypes are overly heterogeneous; hence, including all markers in one screening tube with kappa and lambda is difficult. ASCUS stands for Atypical Cells of Undetermined Significance,and basically means there were mild cellular changes and the the cause in unknown.
