burr cells and ovalocytes

4 View Practicum 1 Review.docx from HUN 1201 at Miami Dade College, Miami. Ovalocytes, sometimes known as elliptocytes, are elongated or misshapen red blood cells that can be hereditary or the result of an acquired disorder. - Blood smear too thick - Blood smear too thin - ATL peripheral blood smear - Normal blood smear - Rouleaux in myeloma - CAD blood smear - Hypertriglyceride milky plasma - Macro-ovalocytes - Elliptocytes - Schistocytes on peripheral smear - Helmet cells - Waring blender syndrome - Tear drop cells - Spherocytes - Blood smear, iron deficiency - Polychromatophilia - Lymphocyte and monocyte ... Burr cells, also known as echinocytes, have a speculated border over the entire cell surface. A poikilocyte is an abnormally shaped cell. The medical advice given should not be considered a substitute for medical care provided by a doctor who can examine you. Crenated cells, or red blood cells that mimic the appearance of burr cells, are frequent artifacts within blood smear tests. The term “poikilocyte” is a generic or umbrella term to describe erythrocytes with abnormal shape. Burr cells are commonly found in both end-stage renal disease and liver disease. The MCHC is not elevated, however, the reticulocyte count may be low. 3 Southeast Asian Ovaloctyes: Ovalocytes show two transverse zones of pallor separated by a transverse zone of cytoplasm. Wherever possible, the red blood cell shape should be identified specifically, e.g. The “Burr” morphology, in this case, is artifactual related to slide preparation and not related to uremia. 1,2 Ovalocytes: Are red blood cells that are oval or egg shaped. Abnormal results mean there is an abnormality in the size, shape, color, or coating of the red blood cells. The presence of burr cells is often indicative of nothing more than an artifact, something created artificially, and is thus of no diagnostic or clinical significance. 5.8). Burr cells, also known as echinocytes, are red blood cells with 10 to 30 small, uniform, evenly-spaced spicules (spikes) ... Ovalocytes are more fragile than normal red blood cells. They can result from chemical contamination, high humidity or from the blood drying slowly. This red blood cell resembles the shape of a coffee bean. 4. In our study, Burr cells were found in 80% of healthy individuals although the numbers of cells are very small. Causes. Schistocytes, Burr Cells (Echinocyte), toxic granulation, Dohle bodies Thalassemic conditions Microcytes, Basophilic Stippling, Pappenheimer bodies, Cabot Rings, Tear Drop Cells, Target Cells If the varying red blood cells are low in number, doctors categorize the condition as +1 Anisocytosis. Conditions of hemoglobinopathies such as sickle cell disease, iron deficiency anemia, liver disease, and splenectomy are detected. Poikilocytes Target Cells (Codocytes) Acanthocytes (Spur cells) Blister Cells Burr Cells ( Echinocytes) Ovalocytes/ This condition also results in mild anemia due to the exaggerated destruction of these ovalocytes. In univariate analysis, burr cells at admission correlated with a mortality rate of 27.3%. The former is typically seen in liver disease while the latter is seen in uremia. 3 Southeast Asian Ovaloctyes: Ovalocytes show two transverse zones of pallor separated by a transverse zone of cytoplasm. Anisocytosis is a condition in which the red blood cells are not even in size. Other tests for diagnosis of specific types of hemolytic anemia are discussed in subsequent chapters. Ovalocytes are red blood cells that have an oval shape rather than the usual round doughnut shape. Poikilocytosis can be defined as the occurrence of poikilocytes in blood. Burr cells appear due to uremia caused by mild hemolysis of red blood cells as seen in hemolytic anemia, hypomagnesemia, hypophosphatemia, and pyruvate kinase deficiency. It often occurs alongside iron-deficiency anemia. Generally, poikilocytosis can refer to an increase in abnormal red blood cells of any shape where they make up 10% or more of the total population. The term is derived from the Greek word ‘poikilos’ meaning ‘varied’. In small numbers, other morphologic variations, including target cells, ovalocytes/elliptocytes, round macrocytes, teardrop cells, polychromasia, stomatocytes, and burr cells, are ambiguous and of little diagnostic significance. Sometimes even a slight decrease in rbc counts may cause a few ovalocytes to be seen. Cell Description: Elliptocytes: Red blood cells are cigar or pencil shaped with parallel sides and an area of pallor. Burr cells are commonly found in both end-stage renal disease and liver disease. 4 Cell Description: Elliptocytes: Red blood cells are cigar or pencil shaped with parallel sides and an area of pallor. 1,2 Macro-ovalocytes: Ovalocytes that are larger than a normal red blood cells. Burr cells, also known as echinocytes, have a speculated border over the entire cell surface. They become significant only when they appear in … 1,2 Macro-ovalocytes: Ovalocytes that are larger than a normal red blood cells. For example, red blood cells interacting with the glass of a microscope slide during a stained blood smear might result in the formation of burr cells. However, there are these abnormal bunches of cells which are called as smudge cells that do not have this well-defined boundary. They are actually the remains of the dead lymphocytes that have combined together into groups. 1,2 Ovalocytes: Are red blood cells that are oval or egg shaped. Stomatocyte. Burr cells type of echinocyte: found in patients with uraemia. A review of 100 randomly chosen patients with burr cells revealed a pattern of associated diseases, that is, acute renal failure, liver failure, and congestive heart failure, different from that of patients with NRBCs. Studies in acanthocytosis workup include a complete blood count (CBC) and a peripheral blood smear. While the red blood cells serve the function of transferring oxygen to the vital parts and organs in the body, white blood cells together serve a number of functions in the body. Although burr cells may be associated with diseases, such as uremia or pyruvate kinase deficiency, crenated cells, that may be confused with true burr cells/echinocytes, are frequent artifacts. Crenated erythrocytes are most commonly caused by excess EDTA (underfilled collection tube), but may also be caused by slow drying, drying in a humid environment, or an alkaline pH from glass slides. Hence, they are also known as Basket Cells. Acanthocytes (from the Greek word acantha, which means thorn), or spur cells, are spiculated red cells with a few projections of varying size and surface distribution (see the images below). Sickle Cell. Acanthocytosis is a red cell phenotype associated with various underlying conditions. We can subclassify poikilocytes by specific shape changes, some of which have fairly unique diagnostic significance, while other forms are quite non-specific. They are commonly seen in cases of iron-deficiency anemia and thalassemia. Ovalocytes are typically seen in cases of low hemoglobin or red blood cells counts, ie anemia. Poikilocytes refer to irregularly shaped RBCs or red blood cells. "if ovalocytes is present what does it mean in a baby that's two months old?" The key to differentiating crenated cells from true burr cells is the frequency with which crenated cells appear in the sample. These red blood cells are crescent-shaped and contain hemoglobin S. This is the tale-tell sign of sickle cell anemia. Burr Cells or Echinocytes – These cells are usually smaller with short, ... Ovalocytes or Elliptocytes – These cells are pencil shaped or egg shaped; the related medical conditions are hereditary elliptocytosis, iron deficiency anemia, other anemia and thalassemias. Take care! Anisopoikilocytosis — variability in both RBC size and shape Ovalocytes sometimes occur in newborn infants. Burr Cells: Liver disease Renal disease Severe burns Bleeding gastric ulcers Maybe artifact Echinocyte (Burr Cell) Acanthocyte vs Echinocyte Howell-Jelly: are intracellular [medical-labs.net] Pediatric blood disorders are a group of noncancerous diseases, including bone marrow failure syndromes and hemoglobinopathies, which can affect the functioning and quality [mskcc.org] Normal red blood cells are round, flattened disks that are thinner in the middle than at the edges. 5. Spur r ed cells have elongated projections while Burr cells are red cells with circumferential blunted borders. ()An increased number of poikilocytes can be life-threatening for the individual too. Many red cells are macrocytic (larger) and oval (ovalocytes), with the mean corpuscular cell volumes increasing to >100 fl. jbmd : You have some abnormalities of shape and size of your red blood cells. Normally, cells have well defined structures with an easily identifiable cytoplasmic membrane. Regarding the pancytopenia, a peripheral blood smear showed a moderate normocytic anemia with mild hypochromia; a few ovalocytes, burr cells, … Diagnosis of Anisocytosis is often triggered falsely due to conditions such as increased WBC count or giant platelets. Elliptocytes and ovalocytes are among the poikilocytes that may be present when there is dyserythropoiesis; they are often present in megaloblastic anaemia (macro-ovalocytes) and in iron deficiency anaemia (“pencil cells”), but they may also be seen in myelodysplastic syndromes and in idiopathic myelofibrosis (see Fig. But if the quantity is found to be greater, it is regarded as a case of +2 Anisocytosis. Cells may be larger or smaller than usual. Neutrophils appear larger than normal with 5-6 nuclear lobes. It may be noted that normal RBCs are flattened, circular discs which are fatter at the borders as compared to the middle portion. The plasma of human blood comprised of many white blood cells and red blood cells. Other abnormalities found on the film, such as elliptocytes, acanthocytes, burr cells, sickle cells, target cells, agglutination, erythrophagocytosis, or parasites, may help reveal the specific disorder causing the hemolysis (Table 20.4). Poikilocytosis — various shapes of red cells; these may include burr cells (echinocytes), acanthocytes, elliptocytes, rouleaux, sickle cells, target cells, teardrop cells, and schistocytes (red cell fragments, helmet cells). Please also discuss with your doctor. Cigar cell - see Elliptocytes below. The presence of teardrop cells (dacrocytes) (Figure below) in the peripheral blood, named for their tear drop shape, is a prominent feature of myelophthisic (marrow infiltrative) conditions, including myelofibrosis, hematologic malignancies, cancer metastatic to the bone marrow, and granulomatous diseases. Cabot's rings are circular or figure-of-eight structures in RBCs that stain red with Wright's stain and are thought to represent nuclear membrane remnants; they are found in similar conditions to Howell-Jolly bodies (see below).
