A Case Report: Acute Myeloid Leukemia (FAB M7)

Area of Science:

• Pediatric Hematology Oncology
• Immunophenotyping in Leukemia Diagnosis
• Childhood Acute Myeloid Leukemia

Background:

• Acute Myeloid Leukemia subtype M7 (AML-M7) represents a rare form of pediatric leukemia, comprising 3-10% of childhood cases.
• Children with AML-M7 can exhibit diverse symptoms, ranging from mild issues like fever and weight loss to severe, life-threatening conditions.
• Early recognition and diagnosis are crucial for effective management of pediatric leukemia.

Observation:

• A 26-month-old boy presented with significant weakness and fatigue, indicative of potential underlying hematological issues.
• Initial clinical presentation prompted further investigation into possible leukemia.
• The patient's symptoms necessitated comprehensive diagnostic evaluation.

Findings:

• Peripheral blood findings revealed abnormalities consistent with leukemia.
• Bone marrow examination confirmed the presence of leukemic cells.
• Immune phenotyping definitively diagnosed the condition as Acute Myeloid Leukemia subtype M7 (AML-M7).

Implications:

• This case highlights the importance of considering rare subtypes of pediatric leukemia, even with non-specific initial symptoms.
• Accurate diagnosis through a combination of methods like immune phenotyping is vital for targeted therapy in pediatric AML-M7.
• Reporting rare cases contributes to a broader understanding of AML-M7 presentation and diagnostic pathways in children.
