Can you list 3 key differences between dog and cat erythrocytes?
1 – dog erythrocytes have a central area of pallor, whilst this is not generally visible.
2 – Cat erythrocytes are smaller in size compered to dog erythrocytes.
3 – Anisocytosis is usually present in cats, whilst dog erythrocytes are usually more uniform in size.
Band neutrophil
2 = monocyte
3 = neutrophil
Eosinophil
Platelet
10 - Platelet
11 - Neutrophil
12 - Eosinophil
Stain precipitate
Hypochromasia – seen in iron deficiency anaemia
(Some polychromatic rbcs are also present on this slide)
Heinz bodies
Acanthocytes - feline hepatic lipidosis and hemangiosarcoma
Spherocytes - small round cells lacking in central pallor
A marked leucocytosis is present – predominant wbc type is lymphocytes
Also no platelets are noted –the patient likely has thrombocytopaenia
The patient was diagnosed leukaemia.
The key point here is there are more lymphocytes than you would typically expect, and they appear abnormal.
You can see normal erythrocytes and normal platelets.
You can also see normal neutrophils – in this case more than you would expect.
The patient had a leucocytosis
Can you see evidence of regeneration?
Haematocrit is 24%
We can see evidence of polychromasia – this degree of polychromasia indicates adequate regeneration.
This patient has a haematocrit of 12%
Is there any evidence of regeneration?
There is no evidence of polychromasia. The arrow shows agglutinated erythrocytes. It is likely that the patient had Immune mediated haemolytic anaemia.
This slide shows a marked neutrophilia, with a left shift and mild toxic changes. (see article above for more details.
The image shows a mild leucocytosis, with an eosinophilia and basophilia – see the article above for more details.
