Echinocyte (from the Greek word echinos, meaning 'hedgehog' or 'sea urchin'), in human biology and medicine, refers to a form of red blood cell that has an abnormal cell membrane characterized by many small, evenly spaced thorny projections. [1] [2] A more common term for these cells is burr cells.
If polychromasia is found in the blood cells, the reticulocyte count is taken to detect further disease or stress. If a low count of reticulocytes is found, it usually indicates bone marrow stress. If a high reticulocyte count is found, it is usually linked to hemolysis, but a Coombs test may be performed in this case to rule out immune ...
Section parallel to the surface from the body of the femur. X 100. a, Haversian canals ; b, lacunae seen from the side; c, others seen from the surface in lamella , which are cut horizontally. Nucleated bone cells and their processes, contained in the bone lacunae and their canaliculi respectively.
Folate helps to reduce the extent of haemolysis in those with significant haemolysis due to hereditary elliptocytosis. [citation needed] Because the spleen breaks down old and worn-out blood cells, those individuals with more severe forms of hereditary elliptocytosis can have splenomegaly. Symptoms of splenomegaly can include: [citation needed]
Döhle bodies are light blue-gray, oval, basophilic, leukocyte inclusions located in the peripheral cytoplasm of neutrophils.They measure 1–3 μm in diameter. Not much is known about their formation, but they are thought to be remnants of the rough endoplasmic reticulum.
Elliptocytes, also known as ovalocytes or cigar cells, are abnormally shaped red blood cells that appear oval or elongated, from slightly egg-shaped to rod or pencil forms. They have normal central pallor with the hemoglobin appearing concentrated at the ends of the elongated cells when viewed through a light microscope .
The cell body varies in size from 5–20 micrometers in diameter and contain 40–60 cell processes per cell, [4] with a cell to cell distance between 20–30 micrometers. [3] A mature osteocyte contains a single nucleus that is located toward the vascular side and has one or two nucleoli and a membrane. [ 5 ]
Acanthocyte-like cells may be found in hypothyroidism, after splenectomy, and in myelodysplasia. [12] Acanthocytes should be distinguished from echinocytes, which are also called 'burr cells', which although crenated are dissimilar in that they have multiple, small, projecting spiculations at regular intervals on the cell membrane.
