Blood Smear Interpretation – finding clues to diagnose disease

Identify the cells in this image from a dog blood smear (Wright giemsa stain)

A is a metamyelocyte and B is a monocyte

A and B are monocytes

A is a band and B is a monocyte

A and B are metamyelocytes

Image of the monolayer of a blood smear stained with Wright Giemsa. What is the most likely cause of this dog’s anaemia?

Immune mediated haemolytic anaemia

Oxidative damage haemolytic anaemia

Haemangiosarcoma

Immune mediated thrombocytopenia

Image of the monolayer of a blood smear stained with Wright Giemsa. What is the most likely cause of this cat’s anaemia?

Immune mediated haemolytic anaemia

Oxidative damage haemolytic anaemia

Mycoplasma haemofelis

Immune mediated thrombocytopenia

Image of the monolayer of a cat blood smear stained with Wright Giemsa. The cat has a mild non-regenerative anaemia and chronic kidney disease. What is the most likely cause of the erythrocyte arrangements?

Rouleaux – incidental finding in a cat

Rouleaux – due to marked hyperglobulinaemia

Agglutination - due to immune mediated haemolytic anaemia

Agglutination – due to Mycoplasma haemofelis

Representative image of the monolayer of a dog blood smear stained with Wright Giemsa. The dog has presented in hypovolaemic shock. What of the following is the most likely cause?

Haemangiosarcoma

Immune mediated haemolytic anaemia

Immune mediated thrombocytopenia

Onion ingestion causing haemolytic anaemia

Image of the monolayer of a dog blood smear stained with Wright Giemsa. What is the significance of the structure indicated by the arrow within the cytoplasm?

Döhle body, indicating acute inflammation

Heinz body, indicating oxidative injury

Bacteria, indicating bacteraemia

Basophil granule, incidental unless there is a basophilia

Image of the monolayer of a cat blood smear stained with Wright Giemsa. What is the structure indicated by the arrow?

Macroplatelet

Lymphocyte

Rubricyte

Platelet clump

Image of the monolayer of a blood smear from an anaemic dog, stained with Wright Giemsa. What is the most likely significance of the cell indicated by the arrow?

Antigenic stimulation

Chronic lymphocytic leukaemia

Regenerative response to anaemia

Acute leukaemia

Image of the monolayer of a blood smear from dog, stained with Wright Giemsa. The analyser indicated a marked lymphocytosis and monocytosis. What is the most likely diagnosis?

Excitement lymphocytosis

Chronic inflammation

Chronic lymphocytic leukaemia

Acute leukaemia

Identify the leukocyte in this image of the monolayer of a cat blood smear stained with Wright Giemsa.

Granular lymphocyte

Metamyelocyte

Mast cell

Basophil
