What are Elliptocytes
John Campbell
Updated on April 08, 2026
Elliptocytes are elongated oval-shaped red blood cells. Very rare elliptocytes may be seen in normal blood smears. Elliptocytes may be increased in iron deficiency anemia (where they are sometimes referred to as “pencil cells”) and marrow infiltrative processes (with teardrop cells
What causes Elliptocytosis?
Hereditary elliptocytosis is caused by a genetic change in either the EPB41, SPTA1, or SPTB gene , and is inherited in an autosomal dominant pattern. Hereditary pyropoikilocytosis is a related condition with more serious symptoms, and is inherited in an autosomal recessive pattern.
Is it normal to have elliptocytes?
Elliptocytosis is often harmless. In mild cases, fewer than 15% of red blood cells are elliptical-shaped. However, some people may have crises in which the red blood cells rupture. This is more likely to happen when they have a viral infection.
What are elliptocytes in blood test?
Elliptocytes, also known as ovalocytes, 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.How do you treat Elliptocytosis?
There is no treatment needed for the disorder unless severe anemia or anemia symptoms occur. Surgery to remove the spleen may decrease the rate of red blood cell damage.
What is a Basophilic erythrocyte?
Basophilic stippling, also known as punctate basophilia, is the presence of numerous basophilic granules that are dispersed through the cytoplasm of erythrocytes in a peripheral blood smear. They can be demonstrated to be RNA.
When do you see elliptocytes?
Note the shape of these appropriately named erythrocytes. In addition to hereditary elliptocytosis, elliptocytes can be seen in hemoglobinopathies, megaloblastic anemia, myelophthisic anemia, congenital dyserythropoietic anemia, sideroblastic anemia, and severe iron deficiency anemia.
Why do Elliptocytes form?
Formation occurs due to erythrocyte membrane protein defects resulting in an increase in mechanical weakness and membrane fragility. Hereditary elliptocytosis occurs due to defects in the horizontal protein linkages between the membrane and cytoskeleton.What are the symptoms of Elliptocytosis?
Hereditary elliptocytosis (HE) refers to a group of inherited blood conditions where the red blood cells are abnormally shaped. Symptoms vary from very mild to severe and can include fatigue, shortness of breath, gallstones, and yellowing of the skin and eyes (jaundice).
What are the symptoms of Poikilocytosis?- fatigue.
- pale skin.
- weakness.
- shortness of breath.
Is autoimmune hemolytic anemia serious?
Autoimmune hemolytic anemia (AIHA) is a group of rare but serious blood disorders. They occur when the body destroys red blood cells more rapidly than it produces them. A condition is considered idiopathic when its cause is unknown. Autoimmune diseases attack the body itself.
What causes odd shaped red blood cells?
Common causes of abnormal red blood cells include: Drepanocytes (sickle cells): sickle cell disease. Spherocytes (cup shaped): autoimmune disorders, transfusion reactions, diseases of newborns, or snakebites. Dacrocytes (teardrop cells): leukemia, megaloblastic anemia, or myelofibrosis.
What causes Burr cells?
Causes: Artificial 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. The basic substances released by a glass slide may raise the pH of the smear, which results in echinocyte formation in vitro.
Is hereditary elliptocytosis Normocytic?
Complete blood count HE elliptocytes are normochromic and normocytic. In HPP, the presence of microspherocytosis contributes to a markedly decreased mean corpuscular volume.
Can Elliptocytosis cause anemia?
Hereditary spherocytosis and hereditary elliptocytosis are congenital red blood cell (RBC) membrane disorders that can cause a mild hemolytic anemia. Symptoms, generally milder in hereditary elliptocytosis, include variable degrees of anemia, jaundice, and splenomegaly.
What is the defect that is responsible for the abnormally shaped RBCs found in hereditary elliptocytosis?

What are the symptoms of Sideroblastic anemia?
The signs and symptoms of sideroblastic anemia may include: fatigue, weakness, the sensation of a pounding or racing heart (palpitations), shortness of breath, headaches, irritability, and chest pain.
What are Elliptocytes and Acanthocytes?
Elliptocytes, also are known as ovalocytes, are oval or cigar-shaped cells with blunt ends. Teardrop cells, or dacryocytes, are abnormal RBCs that have one round and one pointy end. Acanthocytes are the RBCs that have abnormal thorn-like projections (spicules) present on the cell membrane.
How is pyruvate kinase deficiency treated?
- for jaundice: ultraviolet (UV) light (phototherapy) or replacing the baby’s blood with donated blood.
- for anemia: blood transfusions, folic acid, and B vitamins.
- for iron buildup: iron chelation (key-LAY-shun), in which medicines send the extra iron out of the body in pee.
What disease causes basophilic stippling?
Basophilic stippling is seen in lead poisoning, impaired Hb synthesis, alcoholism, and megaloblastic anemias (Figure 61.6A).
What can cause basophilic stippling?
The presence of basophilic stippling is attributed to aggregates of ribosomes or fragments of ribosomal RNA precipitated throughout the cytoplasm of circulating erythrocytes. This finding is associated with acquired and heritable hematologic disorders affecting erythropoiesis and erythrocyte maturation.
Why there is basophilic stippling in lead poisoning?
In contrast to fine basophilic stippling in thalassemia, basophilic stippling is typically coarse in lead poisoning as a result of precipitation of RNA secondary to pyrimidine-5′-nucleotidase inhibition. Coarse basophilic stippling is also reported in pyrimidine-5′-nucleotidase deficiency and arsenic poisoning.
What is the difference between hereditary elliptocytosis and hereditary spherocytosis?
Hereditary spherocytosis is characterized by hemolysis of spheroidal RBCs and anemia. Hereditary elliptocytosis (ovalocytosis) is a rare autosomal dominant disorder in which RBCs are oval or elliptical.
How does Hypersplenism cause anemia?
When your spleen’s overactive, or “hyper,” it removes too many blood cells, including healthy ones. Without enough healthy, mature blood cells, your body has a harder time fighting infections and you may become anemic.
What is dimorphic Anaemia?
Dimorphic anaemia is an anaemia which is due to two deficiencies, iron- deficiency and that of nutritional macrocytic anaemia. It is thus iron-deficiency anaemia complicated by nutritional macrocytic anaemia or may equally well be regarded as nutritional macrocytic anaemia complicated by iron-deficiency.
Why is PNH nocturnal?
For some time, paroxysmal nocturnal hemoglobinuria (PNH) has been known to result from somatic mutations in the PIGA gene, which encodes phosphatidylinositol glycan class A (PIGA). These mutations result in hematopoietic stem cells that are deficient in glycosyl-phosphatidylinositol anchor protein (GPI-AP).
Is Poikilocytosis serious?
Poikilocytes typically develop due to an underlying medical condition that alters their shape. Examples include certain types of anemia, liver disease, kidney disease, and cancer. Poikilocytosis itself is not a fatal condition, but it indicates an underlying medical condition.
What is a Macrocytes?
Macrocytosis is a term used to describe red blood cells that are larger than normal. Also known as megalocytosis or macrocythemia, this condition typically causes no signs or symptoms and is usually detected incidentally on routine blood tests.
What is Rdw in your blood count?
A red cell distribution width (RDW) test is a measurement of the range in the volume and size of your red blood cells (erythrocytes). Red blood cells move oxygen from your lungs to every cell in your body. Your cells need oxygen to grow, reproduce, and stay healthy.
Does hemolytic anemia go away?
Some types of acquired hemolytic anemia are short-term (temporary) and go away over several months. Other types can become lifelong (chronic). They may go away and come back again over time.
What foods to avoid if you are anemic?
- tea and coffee.
- milk and some dairy products.
- foods that contain tannins, such as grapes, corn, and sorghum.
- foods that contain phytates or phytic acid, such as brown rice and whole-grain wheat products.
- foods that contain oxalic acid, such as peanuts, parsley, and chocolate.
