This peripheral blood film (May-Grünwald-Giemsa stain) is from a patient with PMF (also called CIMF) in the prefibrotic stage. You can see scattered teardrop cells (->). Furthermore, a few granulocytic precursors and very few erythroblasts were detected (not shown). The automated cell count showed slight leukocytosis, thrombocytosis and anaemia.

EDTA blood of a female patient with a transitional form of chronic lymphocytic leukaemia/prolymphocytic leukaemia. The three large cells are prolymphocytes, the smaller ones are lymphocytes.

Cell description:
Size: bigger than monoblast
Nucleus: oval, kidney-shaped or lobulated, diffuse chromatin pattern, sometimes with nucleoli
Cytoplasm: pale basophil with fine azurophil granula.
Cell division is still possible.

Cell description:
Size: 15-25 µm
Nucleus: oval with identifiable nucleoli and diffuse chromatin structure Cytoplasm: basophilic with visible golgi-zone and eye-catching azurophil granula (primary granulation)

These so-called 'pseudo-Pelger's nuclear anomalies' with abnormal chromatin condensation and/or deficient nuclear segmentation are often found with viral infections, after chemotherapy, or with a myelodysplastic syndrome (MDS). Conversely, the true Pelger's nuclear anomaly is hereditary and without pathological significance.

Large red blood cell with basophilic stippling (between the two lymphocytes) in a case of auto-immune haemolytic anaemia (AIHA). To the right, next to the lower lymphocyte, there is a polychromatic red blood cell.

Red blood cells of a healthy individual showing a paler centre and a darker border. Occasionally the pale centre has an elongated shape (stomatocytes; at this frequency they have no pathological significance).
