Background: Extramedullary hematopoiesis is known to occur mainly in the organs of reticuloendothelial system. It is very rare for EMH to occur in thyroid nodule without any haematological abnormality.
Case: A 71 year healthy male presented with 3 month history of dysphagia to solids. Clinical examination revealed thyroid nodule measuring 1 cm in diameter in right lobe of thyroid gland. FNAC was performed and microscopic examination showed presence of hematopoietic elements of all the three lineages in the background of benign thyroid follicular epithelial cells. We are reporting this case because of it’s rarity as, no case of EMH with thyroid nodule causing only dysphagia with no haematological abnormality has ever been reported till date.
Conclusion: EMH can present as thyroid nodule with only complaint of difficulty in swallowing with normal haematological parameters. Identification of giant cells as megakaryocyte helps in diagnosis of EMH.
