Heinz Bodies

RBC and Neutrophil

Lymphocyte and Platelet

Other than RBC's what are the two things in this picture

Monocyte (Right) Neutrophil (seg, left)

Echinocytes

RBC with small, uniform spines surrounding cell
Most common cause of formation is an in-vitro artifact which is called crenation.

Acanthocytes

spur cells, altered lipid metabilsm, liver disease
Hemangiosarcoma

Spherocytes

lack of central pallor, smaller than normal. More likely seen in dogs, reduced membrane- macrophage destruction. Immune mediated disease, Hemolytic anemia, transfusion with rejection

Codocytes

target cells, specific leptocyte, common in non-regenerative anemia.

Heinz bodies

round inclusions from disruption in hemoglobin. May be seen in cats normally. Stain blue
Tylenol
onion or garlic
Hyperthyroidism
Lymphosarcoma

Howell jolly bodies

nuclear remnants, response to anemia, usually cleared by spleen

Ghost Cells

a dead cell in which the outline remains visible, but whose nucleus and cytoplasmic structures are not stainable. A red blood cell after loss of its hemoglobin

Schistocytes

some of the irregular shapes appear as helmet cells. Fragments of RBC's, indicative of intravascular hemolysis- mechanical damage to RBC's in circulation. Finding is typical in DIC

Rouleaux

organized stacking or chains of RBC's, normal in equine, suggests inflammatory disease in other species

Hyper-segmented Neutrophil

Greater than 4-5 segments, aged neutorphil, often seen in chronic infections, V-B-12 deficiency (Giant Schnauzer)

acanthocyte

echinocyte

heinz body

howell-jolly body

hypochromasia

pappenheimer

schistocyte

sickle cell

stomatocyte

target cell

ansiocytosis

Abnormal variation in size and color of RBC

poikilocytosis

abnormal variation in shape of RBC

hypochromia

pale cells

macrocytosis

large red blood cells

nucleated red cells

basophillic stippling

punctuate stippling of cell

sickle cells

target cells

cells with dark center and periphery and clear ring in between

spherocytes

spherical cells without pale centers

shistocytes

irregularly contracted cells; fragments

Rouleaux

a clump of red blood cells that appear to be stacked like a roll of coins

agglutination

clumping of RBC's

polychromasia

Term for a pale-blue RBC in routine stains, due to RNA content

anisocytosis

presence of red blood cells of unequal size

hypochromasia

little or no color in cell due to inuffeicient Hb with in the cell. Low Iron.

poikilocytosis

Cells are irregularly shaped

echinocytes

evenly spaced crenation, non-specific disease, rattlesnake envenomation, blood transfusion

acanthocytes

spur cells. resemble creanated cells. have multiple irregularly spaced rounded or clublike projections over entire surface of cell. result from alterations in cell membrane, often seen with kidney or liver disease, hemangiosarcoma, DIC, GN

stomatocytes

uniconcave erythrocytes with mouth like clear area near cell center; a few in a blood smear are insignificant; hereditary in some breeds (alaskan malamutes, schnauzers)

schistocytes

Fractured or fragmented RBC. microangiopathy, DIC, iron deficiency, liver disease, heart failure, GN, hemangiosarcoma

keratocytes

intact or ruptured vesicles on edge of RBC, seen in iron deficiency anemia, liver disease

spherocytes

Sphere spaed, lack central pallor. IMHA, zinc toxicity, blood parasites, bee sting, snake envenomation, transfsion

leptocytes, target cells

Cells with less volume and are 'flattened out.' Folded cell has transverse fold. Target cell looks like a target. Both are associated with chronic anemia, liver disease,dyserythropoiesis

eccentrocytes

Shifting of Hb to one side of the cell, resulting in a clear zone outlined by membrane; oxidant injury: onions, tylenol, vitamin K

Heinz bodies

"nose" of Denatured Hemoglobin, stains well with New Methylene Blue stain, Can be seen in cats, Can lead to anemia. diabetes, hyperthyroidism, lymphoma, or normal

ovalocytes

oval shaped, hereditary in dogs, myelofibrosis, MDS, cats with bone marrow disease, hepatic lipidosis

dacrocytes

tear drop shaped. results from failure of the cell to resume its normal shape after passage thru capillaries. Or, can also be an artifact of smear preparation. Tails same direction= artifact of staining. tails opposite direction= myelofibrosis.

basophilic stippling

deep blue stippling due to ribosomes. regenerative anemia, lead poisoning.

siderocytes

clustered blue dots of iron; lead poising,

Howell-Jolly

remnants of chromatin, severe anemias or aspleenia
