Anisocytosis

Anisocytosis 1 (Canine 1)
Anisocytosis with macrocytes and polychromatophils. Canine (regenerative anemia).

Morphology: variation in red blood cell size due to the presence of red cells larger than normal (macrocytes and  polychromatophils), red cells smaller than normal (microcytes and spherocytes), or both.

Commonly seen with: features of regenerative anemia (macrocytosis and polychromatophils), features of iron deficiency (microcytosis and hypochromasia), features of IMHA (spherocytes, ghost cells, agglutination).

Clinical relevance: depends on underlying condition.

Anisocytosis 5 (Canine 4 - Regen Anemia)
Anisocytosis with macrocytes and polychromatophils. Canine (regenerative anemia).
Anisocytosis 2 (Canine 2 - Macrocytic Normochromic Anemia)
Anisocytosis with macrocytes and polychromatophils. Canine (regenerative anemia).
Anisocytosis 4 (Equine 1 - IMHA)
Anisocytosis with spherocytes. Equine (IMHA).
Microcytes 4 (Canine 4 - Iron Deficiency)
Anisocytosis with hypochromic microcytes and polychromatophils. Neutrophils also visible. Canine (iron deficiency anemia).

  1. Thanks for inquiring. Unfortunately we didn’t have the magnifications documented for these images, but my best guess would be that they are all at 100X except for the second one (canine regenerative anemia), it is zoomed in, and the last one (canine iron deficiency anemia) which looks more like 40X.

    This is a consideration well taken for our future image additions to the site, thank-you!
