Fragmented red blood cells and thrombocytopenia

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.

Frozen blood sample

Blood film of a normal blood sample, which had frozen in the postbox. One can only recognise red blood cell 'shadows' or 'ghosts'.

Gametocyte

Gametocyte in a patient infected with Plasmodium falciparum.

Gaucher cells

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.

Gigant PLT — Giant platelets have their name derived from their size exceeding the size of a normal red blood cell.

Giant platelet

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

Giant platelets in peripheral blood

Peripheral blood (May-Grünwald-Giemsa stain) of a patient with essential thrombocythaemia, ET. Giant platelets (->) are frequently observed in this disease.

Granulated myeloblast 1 — Granulated blasts have a size of 12 - 16 µm and show significant reddish granules in their cytoplasm. The shape of the nucleus is round or oval with a very high nucleocytoplasmic ratio of 70 – 95%.

The chromatin is predominantly regularly distributed and neither clumped nor condensed. The nucleus has a varying number of nucleoli which may be hidden by the chromatin.
