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 ...
On the peripheral blood smear can be found erythrocytes with basophilic stippling (cytoplasmic granules of RNA precipitates) and Pappenheimer bodies (cytoplasmic granules of iron). [13] The anemia is moderate to severe and dimorphic. Microscopic viewing of the red blood cells will reveal marked unequal cell size and abnormal cell shape.
Along with Döhle bodies and toxic vacuolation, which are two other findings in the cytoplasm of granulocytes, toxic granulation is a peripheral blood film finding suggestive of an inflammatory process. [1] Toxic granulation is often found in patients with bacterial infection and sepsis, [1] [2] although the finding is nonspecific. [3]
Toxic vacuolation is associated with sepsis, particularly when accompanied by toxic granulation. [4] The finding is also associated with bacterial infection, [3] alcohol toxicity, liver failure, [4] and treatment with granulocyte colony-stimulating factor, a cytokine drug used to increase the absolute neutrophil count in patients with neutropenia.
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 .
Transient myeloproliferative disease, renamed Transient Abnormal Myelopoiesis (TAM), [32] is the abnormal proliferation of a clone of noncancerous megakaryoblasts in the liver and bone marrow. The disease is restricted to individuals with Down syndrome or genetic changes similar to those in Down syndrome, develops during pregnancy or shortly ...

Critical green inclusions are a rare finding, and when found they are suggestive of a poor prognosis, hence the colloquial term death crystals.A 2018 review found that 56% of patients died shortly after the inclusions were first identified (usually within two weeks). [5]
