Peripheral blood (May-Grünwald-Giemsa stain) of a patient with MDS: on the left a pseudo-Pelger-Huet cell, on the right a dysplastic metamyelocyte. Anaemia and atypical platelets are also present. After peripheral blood and bone marrow analysis the diagnosis of refractory anaemia with excess of blasts (RAEB-1) was made.

Cell description:
Size: up to 20 µm
Nucleus: eccentric with coarsely clumped chromatin, often clock-face chromatin pattern
Cytoplasm: strongly basophilic cytoplasm with apparent less basophilic Golgi zone adjacent to the nucleus

Bone marrow histology (Giemsa stain) of a patient with multiple myeloma showing groups (nests) of plasma cells (->) in atypical locations. Normal plasma cells are usually located close to the blood vessels.

It is of utmost importance to always report a correct value for the platelet concentration. When detecting thrombocytopenia the laboratory should therefore double-check that it is not due to platelet aggregates (->) (pseudo-thrombocytopenia). In a haematology analyser they are usually automatically identified and flagged. In a blood film they are mostly located at the feather edge or the lateral edges.

Platelets can lie on top of red blood cells, and look very much like Plasmodia. (By turning the micrometre screw, one will realize quite easily that the object is on top of the red blood cell and not inside it, as it would be with Plasmodia.)

Platelet satellitosis: Platelets adhere to granulocytes, induced by the anticoagulant EDTA.
