<p>At high magnification the nucleus of a malaria parasite (reddish dot) and the digestive vacuole (bluish ring) are clearly visible. </p>

<p>Malignant melanoma cells have leaked into the peripheral blood (edge of the blood film).</p>

<p>Bone marrow histology (Gomori stain) of a patient showing an infiltration of mantle cell lymphoma cells and an increase in fibres (black lines).</p>

<p>May-Hegglin anomaly belongs to a family of macrothrombocytopenias characterised by mutations in the MYH9 gene. It is a rare autosomal dominant disorder characterised by various degrees of thrombocytopenia that may be associated with purpura and bleeding. </p>

<p>Cell description: </p> <p>Size: 10-12 µm </p> <p>Nucleus: kidney or U-shaped with clumped chromatin </p> <p>Cytoplasm: acidophilic </p> <p>neutrophil: fine reddish granulation </p> <p>Cell division is not possible anymore and protein synthesis has stopped.</p>

<p>Blood film prepared after storage of the EDTA blood for more than one day. A safe morphological differentiation is no longer possible.</p>

<p>Cell description: </p> <p>Size: 20 µm </p> <p>Nucleus: kidney- to band-shaped </p> <p>Cytoplasm: grey and clear with fine azurophilic granules </p> <p>They are shortly located in the peripheral blood and then move into the tissue where they differentiate into macrophages. Function: Phagocytosis either of harmful pathogens or dead, dying or damaged cells from the blood. </p>
