Auto-immune haemolytic anaemia (AIHA) in a case of chronic lymphocytic leukaemia (B-CLL): Reticulocytes are increased, spherocytes are present, Coombs' test is positive.

Phagocytosis of a red blood cell by a monocyte in a case of auto-immune haemolytic anaemia (AIHA). The many spherocytes and polychromasia are clearly visible.

B-ALL/Burkitt lymphoma: The blasts typically show a deep blue cytoplasm and several vacuoles. Tumour cells tend to be very fragile, resulting in 'smudge' cells (->) during blood film preparation.

Size: 10-14 µm
Nucleus: lobulated but often obscured
Cytoplasm: acidophil with purple-black granulation
Function: basophils can release histamine and heparin to respond to a suspected infection
