Neutrophil, promyelocyte - 13.7 Neutrophil, myelocyte - 13.1 Nucleated red cell, normal or abn. - 10.7 The arrowed cells are immature monocytes, which in-clude monoblasts and promonocytes. These cells may have overlapping morphologic features. The arrowed cells in this image have round to oval nuclear contour According to the University of Virginia School of Medicine, the presence of many different types of immature cells, such as myelocytes, promyelocytes and metamyelocytes, indicates a leukemoid reaction. This reaction may be due to malignancy, but also may result from stress, infection or the effects of corticosteroids or other drugs

The cytoplasm has a basophilic character and is devoid of granules, which is a major difference from the myeloblast's successor, the promyelocyte. The nucleolus is the site of assembly of ribosomal proteins, which are located in various particles dispersed over the cytoplasm. Mitochondria are present but have a rather small size Hello Viewers !!!My Name Is Kavindu Lakmal , Medical Laboratory Science graduate From University Of Peradeniya.

Promyelocyte. 12-25 µm; round or oval cell. Cytoplasm is more abundant than in the myeloblast. Note the red- purple primary granules indicating this cell is of the myeloid lineage. Also note the very large size of this cell and that its nucleus is greater than twice the diameter of the red blood cell Myeloblast is the smaller cell to the lower right. It is the first recognizable precursor in the granulocytic series. Relatively high nuclear-to-cytoplasmic ratio. Note nucleoli and agranular cytoplasm. Promyelocyte in upper left.

Myeloblast -Promyelocyte -Myelocyte-Metamyelocyte-Band form -Segmented neutrophils, as ilustrated in the image below. Myeloblast: High nuclear to cytoplasmic ratio, immature chromatin, prominent 3 to 4 nucleoli Promyelocyte: High nuclear to cytoplasmic ratio (but more cytoplasm than Myeloblast), round nucleus with immature chromatin, prominent. Promyelocytes are slightly larger than myelocytes. The nuclei are round to oval, with lacy to coarse chromatin without distinct clumps of condensed chromatin. Nuclei of a few promyelocytes may contain visible nucleoli or nuclear rings, but most do not The cytoplasm of the myeloblast contains granules, and the diameter of a myeloblast is 20 µm. Myeloblasts undergo granulopoiesis process and develop into granulocytes. The stages involve the development into promyelocyte to myelocyte to metamyelocyte and finally into band cells called the basophils, eosinophils, and neutrophils

A promyelocyte (or progranulocyte) is a granulocyte precursor, developing from the myeloblast and developing into the myelocyte.Promyelocytes measure 12-20 microns in diameter. The nucleus of a promyelocyte is approximately the same size as a myeloblast but their cytoplasm is much more abundant. They also have less prominent nucleoli than myeloblasts and their chromatin is more coarse and clumped From there, the formal sequence of precursor development is myeloblast → promyelocyte → myelocyte → metamyelocyte → band neutrophil → segmented neutrophil (Chap. 60). The term granulocyte often is loosely used to refer to neutrophils but strictly speaking includes eosinophils and basophils. Eosinophilic (Chap. 62) and basophilic.

Metamyelocytes, together with myelocytes and promyelocytes, are precursors of neutrophils, the largest class of white blood cell. These immature neutrophils are normally found only in the bone marrow. In the blood, it is metamyelocytes that are the most often observed, accompanied by a few myelocytes.

The myeloblast differentiates into a promyelocyte that becomes irreversibly committed to the neutrophilic cell line. This cell is large, with a large round nucleus, prominent nucleoli, and purple azurophilic granules. These granules are primary, nonspecific granules. Promyelocytes also give rise to eosinophils and basophil Elliptocytes and ovalocytes are formed only after the red blood cell has reached its normal and mature morphology. Elliptical features develop over time as the cell undergoes stress in the circulation. 1,2.

There can be less than 20% blasts in the peripheral blood and more than 20% in the bone marrow In the most common clinical picture, drug-induced acute agranulocytosis, the bone marrow is either poor in cells or lacks granulopoietic precursor cells (aplastic state), or shows a maturation block at the myeloblast-promyelocyte stage. The differential diagnosis of pure agranulocytosis versus aplasias of several cell lines is outlined on.

Acute promyelocytic leukemia is a form of acute myeloid leukemia, a cancer of the blood-forming tissue (bone marrow). In normal bone marrow, hematopoietic stem cells produce red blood cells (erythrocytes) that carry oxygen, white blood cells (leukocytes) that protect the body from infection, and platelets (thrombocytes) that are involved in blood clotting Acute myeloid leukaemia • Acute myeloid leukaemia (AML) has an incidence of 2 - 3 per 100 000 per annum in children, rising to 15 per 100 000 in older adults. 17.
