The word "micromyeloblast" is a medical term that refers to an immature white blood cell. Its spelling can be explained using the International Phonetic Alphabet (IPA). The first syllable "mi-" sounds like "my" and the "cr" ending is pronounced as "kro." The "o" before the "myelo" part is pronounced like "uh." The second syllable "myelo" is pronounced as "my-uh-lo" and the final part "blast" is said as "blahst." By breaking down the phonetics, we can quickly and accurately spell complex medical terms like "micromyeloblast."
Micromyeloblast is a term used in the field of hematology and pathology. It refers to an immature cell of the myeloid lineage, which can be observed microscopically during the evaluation of bone marrow samples. Specifically, micromyeloblasts are small-sized cells with a round or slightly indented nucleus and a high nuclear-cytoplasmic ratio. These cells possess a fine chromatin pattern, prominent nucleoli, and a scanty cytoplasm that may contain azurophilic granules. Micromyeloblasts are considered less mature than promyelocytes and more mature than myeloblasts.
The presence of micromyeloblasts in the bone marrow can be indicative of certain hematological conditions, such as acute myeloid leukemia (AML). In patients with AML, an abnormal proliferation of myeloid precursors occurs, and the presence of micromyeloblasts in the bone marrow is one of the criteria used for diagnosis. Additionally, certain subtypes of AML, such as acute promyelocytic leukemia (APL), are characterized by a higher proportion of micromyeloblasts compared to other variants.
In summary, a micromyeloblast is an immature cell of the myeloid lineage that can be observed in the bone marrow. Its presence and characteristics are significant in the diagnosis and classification of certain hematological conditions, particularly acute myeloid leukemia.

The word "micromyeloblast" has its roots in Greek and Latin.
- The prefix "micro-" comes from the Greek word "mikrós", meaning small or tiny.
- The root word "myelo-" is derived from the Greek "muelon", which means marrow. This root is commonly used in medical terminology to refer to bone marrow.
- The suffix "-blast" is from the Greek word "blastos", meaning germ or sprout, often used to refer to an immature or developing cell.
By combining these elements, "micromyeloblast" refers to a small or tiny immature cell found in the bone marrow.
