Background:
Extramedullary hematopoeisis (EMH) can occur in various physiological and pathologic states. The spleen is the most common site of EMH.
Case presentation:
We report a case with hereditary persistence of fetal hemoglobin with extramedullary hematopoiesis presented as cord compression and cytopenia secondary to multi-paraspinal masses.
Conclusion:
Treatment can be a challenge. Relapse is a possibility.
