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 …

Jul 8, 2023 · The main difference between acanthocytes and echinocytes is that acanthocytes have small regular projections, whereas echinocytes have larger, irregular projections. Acanthocytes and echinocytes are two forms of red blood cells with abnormal cell walls.

Nov 21, 2023 · Burr Cells, also known as echinocytes or crenation, are abnormally shaped red blood cells with a characteristic deformity called spicules. Spicules of burr cells are numerous (10-30), evenly...

Three of the most common morphologies are burr cells (echinocytes), acanthocytes, and target cells. This topic discusses their mechanisms of formation and their usefulness in identifying systemic disorders.

Nov 10, 2016 · 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. A more common term for these cells is burr cells. Appearance:

Dec 20, 2013 · Acanthocytes are irregularly spiculated cells (spicules are irregular in size, shape and distribution around the RBC membrane), whereas echinocytes are regularly spiculated cells. In this compilation of images from a blood smear of a dog with disseminated intravascular coagulation, acanthocytes are seen (arrows, A and B).

Echinocytes are spiculated red blood cells in which the spicules are relatively evenly spaced over their entire surface and are similar in size to sea urchins. Echinocytes are the predominant red blood cell shape abnormality in human burn patients.

The formation of echinocytes is a reversible process and can reform a natural discoid shape. 3 Echinocytes are often considered artifact from the smear making process (drying or staining) and may not be reported, depending on individual laboratory protocol.

Echinocytes are erythrocytes with evenly distributed pointed projections (see Fig. 64.3 B). Echinocytosis is observed in uremia, liver disease, hypomagnesemia, hypophosphatemia, postchemotherapy, and in athletes after heavy physical exercise.

Burr cells are red blood cells with 10-30 uniform, short, blunt projections distributed evenly around the circumference of the cell, giving the red cell surface a serrated appearance. The red blood cells retain central pallor. Seen in uremia or pyruvate kinase deficiency, and to a lesser extent post splenectomy, burns and hepatitis of the newborn.
