What do pappenheimer bodies indicate?
Pappenheimer bodies are seen in certain types of anemia that are characterized by an increase in the storage of iron, such as sideroblastic anemia and thalassemia. These inclusions are also seen in the peripheral blood following a splenectomy.
What is autosplenectomy?
An autosplenectomy (from ‘auto-‘ self, ‘-splen-‘ spleen, ‘-ectomy’ removal) is a negative outcome of disease and occurs when a disease damages the spleen to such an extent that it becomes shrunken and non-functional.
What is Holly Jolly bodies?

Where are Heinz bodies found?
Heinz bodies, first discovered by Dr. Robert Heinz in 1890 and otherwise known as Heinz-Erlich bodies, are clumps of damaged hemoglobin located on red blood cells. When hemoglobin becomes damaged, it can cause your red blood cells to stop working properly.
Is splenic sequestration painful?
Splenic sequestration can be very painful. Young infants will not have energy to play and will appear extremely drowsy or lack energy and will be hard to awaken. Acute splenic sequestration is an emergency. Seek medical treatment right away.
What triggers splenic sequestration?
Acute splenic sequestration happens when sickled red blood cells get trapped in the spleen, causing the spleen to enlarge. Sickle cell disease affects the red blood cells causing them to sickle or become banana-shaped. The main purpose of red blood cells (RBCs) is to deliver oxygen to the body.
How are Heinz bodies removed?
In the normal adult, Heinz bodies are removed from the circulation by the spleen and are therefore not seen in the peripheral blood. However, after splenectomy or in congenital asplenia, Heinz bodies are found in the peripheral blood.
What do Heinz bodies look like?
Heinz bodies look like small dark spots inside red blood cells. They form when hemoglobin molecules in the red blood cells break down due to oxidative damage. 1 Hemoglobin is a red blood cell protein that binds to and carries oxygen to cells throughout the body.
What drugs cause Heinz bodies?
Veterinary. In veterinary medicine, Heinz bodies are associated with the consumption of paracetamol (acetaminophen), garlic, and onions by cats, dogs, and various primates. Thiosulfate compounds in the flesh of onions have been identified as the cause.
