Normal lymphocyte.
<p>Normal lymphocyte.</p>
Cell description:
Size: 10-16 µm
Nucleus: round or slightly indented with condensed and cloddy chromatin, usually invisible nucleolus
Cytoplasm: scanty, weakly basophilic, may have small numbers of azurophilic granules
Morphologically functional subset of lymphocytes cannot clearly be distinguished.
Function: recognize and eliminate threats to the body. Lymphocytes of the innate immune system deliver an immediate response to viral attack. Lymphocytes of the adaptive immune system are specific to a particular antigen.

In the peripheral blood (May-Grünwald-Giemsa stain) of this patient lymphoma cells can be detected. They show a large, deeply indented nucleus (->) and scanty cytoplasm. Further diagnostics confirmed a mantle cell lymphoma.

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.

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