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 bone marrow smear demonstrating myeloid hyperplasia seen in a patient with chronic myelogenous leukemia (50X oil immersion). A few erythroid precursors are present.
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).
A peripheral blood smear picture showing a dimorphic population of red blood cells: hypochromic, microcytic RBCs next to normochromic, normocytic RBCs (50X oil immersion). A neutrophil (left) and a monocyte (right) are also present.
An image from a fluid cytospin slide demonstrating a mott cell (center) with round globules beside a nucleated red blood cell (right). Many neutrophils and a couple of monocytes are also present (60X oil immersion).
An image from a peripheral blood smear showing marked poikilocytosis, including a pyknocyte (center), many acanthocytes, spherocytes, and bite cells (100X oil immersion). A monocyte is also present (right).
An image from a peripheral blood smear showing marked poikilocytosis, including pyknocytes, acanthocytes, bite/blister cells, and spherocytes (50X oil immersion) along with various white blood cells.
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 peripheral blood smear showing a monocyte (center) with vacuolation beside a blast (50X oil immersion). Another monocyte and blasts are also present.
