The presence of Heinz bodies represents damage to hemoglobin and is classically observed in G6PD deficiency, a genetic disorder that causes hemolytic anemia. In veterinary medicine, Heinz bodies may be seen following the consumption of foods containing thiosulfate and propylene glycol compounds by cats, dogs and certain primates.
Most individuals with G6PD deficiency are asymptomatic.When it induces hemolysis, the effect is usually short-lived. [5]Most people who develop symptoms are male, due to the X-linked pattern of inheritance, but female carriers can be affected due to unfavorable lyonization or skewed X-inactivation, where random inactivation of an X-chromosome in certain cells creates a population of G6PD ...
A degmacyte or bite cell is an abnormally shaped mature red blood cell with one or more semicircular portions removed from the cell margin, known as "bites". [1] [2] These "bites" result from the mechanical removal of denatured hemoglobin during splenic filtration as red cells attempt to migrate through endothelial slits from splenic cords into the splenic sinuses.

A cell containing Pappenheimer bodies is a siderocyte. Reticulocytes often contain Pappenheimer bodies. They are mostly observed in diseases such as myelodysplastic syndrome (MDS), sideroblastic anemia, hemolytic anemia, lead poisoning and sickle cell disease. They can interfere with platelet counts when the analysis is performed by electro ...
Splenectomy patients typically have Howell-Jolly bodies [11] [12] and less commonly Heinz bodies in their blood smears. [13] Heinz bodies are usually found in cases of G6PD (Glucose-6-Phosphate Dehydrogenase) and chronic liver disease. [14] A splenectomy also results in a greatly diminished frequency of memory B cells. [15]
They are seen on blood films in abetalipoproteinemia, [3] liver disease, chorea acanthocytosis, McLeod syndrome, and several inherited neurological and other disorders such as neuroacanthocytosis, [4] anorexia nervosa, infantile pyknocytosis, hypothyroidism, idiopathic neonatal hepatitis, alcoholism, congestive splenomegaly, Zieve syndrome, and ...

Cabot Rings, considerably rare findings, when present are found in the cytoplasm of red blood cells and in most cases, are caused by defects of erythrocytic production [2] and are not commonly found in the blood circulating throughout the body.
