The following pictures are of basophils which are the rarest of blood cells. Basophils are granular leukocytes with bilobed nuclei. Due to lots of histamine containing granules, they stain blue often the nucleus is obscured. However, the nucleus is barbell shaped like an eosinophil. They are often confused with lymphocytes. First, Lymphocytes are agranular; you can clearly see the nucleus. Second basophils are 2-3x the size of a red blood cell whereas lymphocytes are only 1.5x the size of a red blood cell.
Most of the pictures on this page were all taken from a pathology slide collected at Oakland Hospital in 1956. Sadly, the slide disintegrated in 2013. Scroll through the pictures using the arrow buttons observing the bsophils. When done, try to identify the basophils on this page .
