Here's what I think I know about lymphocyte count and MDS. The two major components of your white blood cell count are neutrophils and lymphocytes, at least when your blood count is normal. It is fairly common for the lymphocyte count to be depressed with MDS as lymphocytes are produced in the marrow along with neutrophils, monocytes, eosonophils, etc. Lymphocytes start off as a generic white blood cell, then migrate to the Thymus to mature and differentiate. If the factory (marrow) isn't producing enough white blood cells, or defective white blood cells, then your lymphocyte count may have problems along with your neutrophil count.
