What do hypersegmented neutrophils indicate?

Hypersegmented neutrophils may be seen in a few conditions. Most often hypersegmented neutrophils are associated with megaloblastic anemia and are said to be pathognomonic of the disease. Megaloblastic anemia can be caused by folic acid deficiency or vitamin B12 deficiency (including pernicious anemia).

Why do neutrophils become Hypersegmented?

Hypersegmented neutrophils are classically seen with folate (vitamin B 9) orcobalamin (vitamin B 12) deficiency. These morphologic changes of the neutrophil nucleus occur due to impaired DNA synthesis from inadequate substrate or impaired replication from a toxin or medication effect.

Which of the conditions is associated with the presence of hypersegmented neutrophils in the PS?

Megaloblastic anemia is characterized by larger than normal circulating red blood cells and hypersegmented neutrophils.

What causes megaloblastic anemia?

Causes. There are many causes of megaloblastic anemia, but the most common source in children occurs from a vitamin deficiency of folic acid or vitamin B-12. Other sources of megaloblastic anemia include the following: Digestive diseases — Certain diseases of the lower digestive tract can lead to megaloblastic anemia.

What are Vacuolated neutrophils?

Toxic vacuolation, also known as toxic vacuolization, is the formation of vacuoles in the cytoplasm of neutrophils in response to severe infections or inflammatory conditions.

What does few tear drop cells mean?

The presence of teardrop-shaped cells may indicate: Myelofibrosis. Severe iron deficiency. Thalassemia major. Cancer in the bone marrow.

What causes tear drop cells?

Teardrop cells (dacrocytes) are frequently associated with infiltration of the bone marrow by fibrosis, granulomatous inflammation, or hematopoietic or metastatic neoplasms. They can also be seen in patients with splenic abnormalities, vitamin B12 deficiency, and some other forms of anemia.

Who is at risk for megaloblastic anemia?

Common risk factors of megaloblastic anemia include nutritional factors, alcoholism, elderly, pregnant, vegans, and malabsorptive syndromes.
