![Flocculated cryoglobulin in phase contrast microscopy image Flocculated cryoglobulin in phase contrast microscopy image](/fileadmin/media/f100/images/CellImages/2008_11_figure3_hires.jpg)
In the impedance channel of a haematology analyser a falsely elevated platelet concentration of 850,000/μL was measured. This was caused by precipitated cryoglobulin in cryoglobulinaemia. The flocculated cryoglobulin is visible in the phase contrast microscope in between the red blood cell 'rouleaux'.

Fragmented red blood cells and thrombocytopenia in the case of a thrombotic thrombocytopenic purpura (TTP). In the partially thrombosed capillaries the red blood cells are exposed to a high degree of shearing force, which causes them to burst.

Bone marrow histology (periodic acid Schiff stain, PAS) displaying macrophages on the left, with a cytoplasm resembling crinkled parchment. They are so-called 'Gaucher' cells. Gaucher's disease is characterised by a congenital defect of the enzyme glucocerebrosidase leading to an increase of certain glycolipids (cerebrosides) inside the macrophages. On the right side of the picture the bone marrow appears normal.

Giant platelet with prominent granulation from a patient with essential thrombocythaemia (ET). (Defective haematopoiesis causes detectable poikilocytosis.)
