An image from a bone marrow smear showing a macrophage (center) with ingested red blood cells, vacuolation, and hemosiderin (iron) granules seen in a patient with a normal bone marrow (100X oil immersion).
An image from a peritoneal fluid cytospin slide demonstrating many macrophages, polymorphonuclear cells, and monocytes (60X oil immersion). Macrophages have vacuolation and a few have ingested red blood cells (bottom-left, bottom-right).
An image from a Cerebrospinal Fluid (CSF) cytospin slide showing two lymphocytes (center, bottom right), two neutrophils (center left, center right), and a nucleated red blood cell (bottom) surrounded by red blood cells (60X oil immersion).
An image from a peritoneal fluid cytospin sample demonstrating macrophages with vacuolation (right) and two mesothelial cells (left) surrounded by eosinophils seen in a patient with a parasitic infection (60X oil immersion).
An image from a peritoneal fluid cytospin slide demonstrating macrophages, monocytes, and polymorphonuclear cells (100X oil immersion). A mesothelial cell (center) with abundant pale blue cytoplasm and a round nucleus is also found.
An image from a Cerebrospinal Fluid (CSF) cytospin slide demonstrating a mitotic figure (center) surrounded by numerous plasmacytoid lymphocytes (60X oil immersion).
An image from a bone marrow particle smear stained with an iron stain (Perls Prussian Blue) showing two macrophages with blue hemosiderin granules (50X oil immersion).
