Paroxysmal nocturnal haemoglobinuria

Mild anisocytosis, sporadically ovalocytes and dacrocytes, a lymphocyte on the left and a segmented neutrophil on the right.

Basophilic erythroblasts are marked by yellow arrows, a proerythroblast is marked by a cyan arrow, and oxyphilic erythroblasts (with slightly disrupted contour of cytoplasm) are marked by green arrows. A karyorrhectic figure of an erythroblast is marked by a black arrow, and a bare nucleus of a megakaryocyte is marked by a white arrow. The unmarked nuclear elements are degranulated granulocytes.
