Circulating lymphocytes (white blood cells or mononuclear leukocytes) are variable in size. Depending on their size, they are characterized as being either small, medium or large. The majority of lymphocytes circulating in the blood stream are small or medium sized. This is a small lymphocyte. It measures approximately 7micrometers in diameter. The nucleus of these small lymphocytes often shows a small indentation. The surrounding cytoplasm presents itself as a thin rim, pale blue in colour. The cytoplasm occasionally reveals a few very fine granules. Wrights stain.
