A 35-year-old man presents with anemia, neutropenia, thrombocytopenia, myeloblasts with the presence of Auer rods, and one or two distinct nucleoli and promyelocytes. Cytochemistry examination demonstrates peroxidase and Sudan black B (SBB) positive and TdT terminal eoxynucleotidyl transferase (TdT) negative. This hematologic picture is consistent with: A) Acute lymphoblastic leukemia (ALL) B) Acute myeloblastic leukemia (AML) C) Chronic myelocytic leukemia (CML) D) Chronic lymphocytic leukemia (CLL) E) None of the above

The hematologic picture is consistent with Acute myeloblastic leukemia (AML). Therefore the correct option is B.

Explanation:

Leukaemia is a type of cancer that affects the blood forming tissues such as the bone marrow, leading to excessive or over production of abnormal blood cells ( usually the white blood cells). They occur in two categories; it can be Acute leukaemia or Chronic leukaemia.

There are different forms of acute leukaemia which is classified according to the lineage ( myeloid or lymphoid). They include:

- Acute Myeloblastic Leukaemia (AML)and

- Acute Lymphoblastic Leukaemia ( ALL).

In AML, the following Laboratory diagnosis differentiates it from other leukaemia, these includes:

- myeloblasts with the presence of Auer rods, and one or two distinct nucleoli and promyelocytes, and

-peroxidase and Sudan black B (SBB) positive and TdT terminal eoxynucleotidyl transferase (TdT) negative. Therefore the correct option is B

a- multicellular

b-eukaryotic
