Hematogone Hyperplasia Masquerading as Acute Lymphoblastic Leukemia With Concurrent Hypercupremia

Area of Science:

• Hematology
• Pediatric Medicine
• Toxicology

Background:

• Copper homeostasis is crucial for hematologic health, with deficiency documented in adults causing bone marrow abnormalities.
• Hematogone hyperplasia is a rare finding in copper-related hematologic disorders.
• The effects of mild copper excess on hematopoiesis, particularly in pediatrics, remain largely undocumented.

Observation:

• A pediatric patient presented with pancytopenia (abnormally low blood cell counts).
• The patient exhibited hypercupraemia (elevated serum copper levels).
• Bone marrow examination revealed hematogone hyperplasia.

Findings:

• The study describes a unique case of pediatric pancytopenia linked to copper excess, not deficiency.
• Hematogone hyperplasia was observed in conjunction with hypercupraemia.
• Zinc therapy effectively normalized serum copper levels and resolved pancytopenia.

Implications:

• This case expands the understanding of copper's role in pediatric hematopoiesis.
• It suggests copper excess as a potential, albeit uncommon, cause of pancytopenia in children.
• Highlights zinc therapy as a successful treatment for copper-induced hematologic abnormalities.
