Middle Ear Extramedullary Hematopoiesis: A Case Report.

Background: Extramedullary hematopoiesis (EMH) in the middle ear is exceedingly rare, with fewer than five cases reported. The authors report the first Thai case of middle ear EMH Case Report: A 32-year-old Thai thalassemic man presented with complaint of right-sided hearing loss from a middle ear mass. The CT/MRI was done and the diagnosis of EMH was confirmed by a pathological examination after a surgical removal. Conclusion: A differential diagnosis of EMH should also be done in thalassemic patients presented with a middle ear mass.
