Autoimmune haemolytic anaemia with cold antibodies

Marked agglutination of erythrocytes – due to the presence of cold antibodies – makes description of the blood smear impossible.

Numerous erythroblasts of different ages, some of them are macrocytic, other are normocytic (erythropoiesis is of macro-normoblastic character). A promyelocyte is marked by a yellow arrow, a neutrophilic myelocyte is marked by a red arrow, band cells are marked by cyan arrows, and a segmented eosinophil is marked by a black arrow.

Numerous erythroblasts of different ages, most of them are macrocytic (erythropoiesis is of macroblastic character). A neutrophilic myelocyte is marked by a red arrow, a metamyelocyte is marked by a cyan arrow, and a segmented neutrophil is marked by a green arrow.
