Myelofibrosis and vitamin D deficient rickets--a rare association

Area of Science:

• Hematology
• Pediatrics
• Nutritional Medicine

Background:

• Myelofibrosis is a rare myeloproliferative neoplasm characterized by bone marrow fibrosis.
• Infantile myelofibrosis is exceptionally uncommon, presenting diagnostic challenges.
• Vitamin D deficiency rickets typically affects bone mineralization, not hematopoiesis directly.

Observation:

• A 6-month-old infant presented with symptoms suggestive of a hematological disorder.
• Diagnostic workup revealed myelofibrosis.
• The infant was concurrently diagnosed with severe Vitamin D deficient rickets.

Findings:

• This case demonstrates a rare association between myelofibrosis and Vitamin D deficient rickets in an infant.
• The underlying mechanism linking rickets to myelofibrosis in this case is explored.
• Literature review confirms the rarity of this co-occurrence.

Implications:

• Highlights the importance of considering nutritional deficiencies in infantile hematological disorders.
• Suggests potential pathways where severe rickets might influence bone marrow microenvironment.
• Underscores the need for comprehensive evaluation in pediatric myelofibrosis cases.
