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 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 bone marrow smear showing a macrophage with a valuolated and granular cytoplasm seen in a patient with a normal bone marrow (100X oil immersion).
An image from a Cerebrospinal Fluid (CSF) cytospin slide showing multiple macrophages with ingested red blood cells, vacuolation, and hemosiderin granules (60X oil immersion).
An image from a peritoneal fluid cytospin slide demonstrating macrophages, monocytes, polymorphonuclear cells, lymphocytes, and mesothelial cells (20X).
An image from a bone marrow particle smear stained with an iron stain (Perls Prussian Blue) showing a macrophage with blue hemosiderin granules (50X oil immersion).
