L 1st Row- Acanthocytosis- RBCs show many spicules due to an unstable redcell membrane lipid structure (eg in abetalipoproteinaemia)

R 1st Row- Basophilic stippling- Denatured RNA found in RBCs indicating accelerated erthyropoiesis or defective Hb synthesis. Seen in lead poisoning, megaloblastic anaemia, myelodysplasia, liver disease and haemoglobinopathy such as thalassaemia.

L 2nd Row- Burr Cells- Irregularly shaped cells occurring in uraemia.

R 2nd Row- Rouleaux formation- RBCs stacked on each other (causing raised ESR). Seen in chronic inflammation, paraproteinaemia and myeloma.
