Wright stain of peripheral blood featuring a monoblast and an immature monocytic cell. The cytoplasmic disintegration of the nucleated cell to the left is artifactual. However the nuclear features of this cell are well preserved and characteristic of a monoblast with fine chromatin, prominent nucleoli and small indentations. The nucleated cell on the right has ample cytoplasm with pseudopods and vacuoles. It possesses a rounded nucleus with several nucleoli and slightly darker chromatin indicating a degree of maturation yet still retaining features indicative of an immature monocytic cell.
