WHO Classification of Disease
| Structure | Disease |
|---|---|
| Book | Haematolymphoid Tumours (5th ed.) |
| Category | Myeloid proliferations and neoplasms |
| Family | Acute myeloid leukaemia |
| Type | Acute myeloid leukaemia, defined by differentiation |
| Subtype(s) | Acute monocytic leukaemia |
Definition / Description of Disease
Acute monoblastic and monocytic leukemia are myeloid leukemias in which the peripheral blood or bone marrow has ≥20% blasts (including promonocytes) and in which ≥80% of the leukemic cells are of monocytic lineage (monoblasts, promonocytes and monocytes). Neutrophils may be noted (<20%). In acute monoblastic leukemia, most (≥80%) of the monocytic cells are monoblasts; while in acute monocytic leukemia, most of the monocytic cells are promonocytes or monocytes. In the 2016 revision to the World Health Organization (WHO) classification system, acute monoblastic and monocytic leukemia is a distinct entity within the section of HAEM4:Acute Myeloid Leukemia (AML), Not Otherwise Specified[1][2]. This entity does not meet the criteria for inclusion in any of the other AML groups (i.e. AML with Recurrent Genetic Abnormalities, AML with Myelodysplasia-Related Changes, or Therapy-Related Myeloid Neoplasms).
Synonyms / Terminology
Acute monoblastic leukemia; acute monocytic leukemia; French-American-British (FAB) classification M5, Monoblastic leukemia NOS
Epidemiology / Prevalence
Acute monoblastic leukemia:
- less than 5% of AML cases
- more common in young individuals
Acute monocytic leukemia:
- less than 5% of AML cases
- more common in adults; the median patient age is 49 years
- the male-to-female ratio is 1.8:1
Clinical Features
Put your text here and fill in the table (Instruction: Can include references in the table. Do not delete table.)
| Signs and Symptoms | EXAMPLE: Asymptomatic (incidental finding on complete blood counts)
EXAMPLE: B-symptoms (weight loss, fever, night sweats) EXAMPLE: Fatigue EXAMPLE: Lymphadenopathy (uncommon) |
| Laboratory Findings | EXAMPLE: Cytopenias
EXAMPLE: Lymphocytosis (low level) |
editv4:Clinical FeaturesThe content below was from the old template. Please incorporate above.
Sites of Involvement
Bone marrow; extramedullary sites such as lymph nodes, skin, gingiva, and CNS.
Morphologic Features
- Monoblasts are large cells with abundant cytoplasm, which can be moderately to intensely basophillic, and round nuclei with delicate lacy chromatin and one or more predominant nucleoli; scattered azurophillic granuoles and vacuoles may be present.
- Promonocytes have a more irregular and delicately convoluted nuclear configuration and cytoplasm which is usually less basophillic and more granulated.
- Hemophagocytosis (erythrophagocytosis) may be observed, often associated with t(8;16)(p11.2;p13.3).
- The extramedullary lesion may be composed mainly of monoblasts, promocytes or both.
Immunophenotype
Cytochemistry
- Monoblast granules and monocytes are strongly positive for non-specific esterase and lysozyme in most cases
- Monoblasts are typically negative for myeloperoxidase (MPO), although promonocytes may have scattered positivity.
Often a complex immunophenotype with multiple blast populations including:
- immature blasts with CD34 (30% of cases) and/or KIT (CD117) expression
- populations with myeloid markers: CD13, CD33, CD15, CD65
- populations with at least two monocytic markers: CD4, CD14, CD11b, CD11c, CD64, CD36, CD68, and lysozyme
- most cases are positive for HLA-DR
- MPO can be expressed in acute monocytic leukemia and less often in monoblastic leukemia
| Finding | Marker |
|---|---|
| Positive (universal) | EXAMPLE: CD1 |
| Positive (subset) | EXAMPLE: CD2 |
| Negative (universal) | EXAMPLE: CD3 |
| Negative (subset) | EXAMPLE: CD4 |
Chromosomal Rearrangements (Gene Fusions)

- Chromosomal Rearrangements (Gene Fusions)
- Individual Region Genomic Gain/Loss/LOH
- Characteristic Chromosomal Patterns
- Gene Mutations (SNV/INDEL)
Diagnosis
- The main differential diagnoses of acute monoblastic leukemia include: AML without maturation, AML with minimal differentiation, AML with t(9;11)(p21.3;q23.3), and acute megakaryoblastic leukemia (AMKL)[2]. Extramedullary monoblastic sarcoma needs to be differentiated from malignant lymphoma or soft tissue sarcomas[2].
- The main differential diagnoses of acute monocytic leukemia include: chronic myelomonocytic leukemia, acute myelomonocytic leukemia, and microgranular acute promyelocytic leukamia (APL)[2].
- Haemophagocytosis (erythrophagocytosis) with t(8;16)(p11.2;p13.3) may also occur in acute myelomonocytic leukemia and some cases of AML with maturation[2].
