Dense infiltration of bone marrow by B-CLL
<p>Bone marrow cytology (May-Grünwald-Giemsa stain) of a patient with B-CLL: Dense infiltration of the bone marrow by the B-CLL. Megakaryocyte count and morphology are normal.</p>
Diagnosis of AML in bone marrow
<p>Diagnosis of AML in the bone marrow: Characteristic are bundles of Auer rods (->) and many atypical promyelocytes.</p>
Disturbed cell distribution
<p>During the preparation of a large number of blood films for EQA purposes, the blood drop on the slide had already started to dry prior to smearing, so that, when the blood film was made, many white blood cells were pulled towards the edge, resulting in disturbed cell distribution.</p>
Doehle bodies 1
<p>Doehle bodies were named after the German pathologist Karl Gottfried Paul Döhle (1855-1928). They are defined as light blue-grey oval inclusions with a diameter of 1 to 3 µm located in the peripheral cytoplasm of mature and immature neutrophils. The structures are seemingly derived from the rough endoplasmic reticulum and hence contain RNA. They are often present in conjunction with toxic granulation.</p>

Drop of saliva
<p>At low magnification, a drop of saliva is easily detected. When enlarged considerably, it might cause confusion.</p>
Echinocytes
<p>Echinocytes ('sea urchin cells') of a healthy individual resulting from prolonged storage of the EDTA blood (24 hours).</p>
Echinocytes
<p>Large number of echinocytes of a healthy individual resulting from prolonged storage of the EDTA blood (48 hours).</p>
Edge of blood film
<p>The edge of a correctly prepared blood film from a normal blood sample. Relatively few white blood cells can be seen in this example.</p>
