Massive hemothorax due to intrathoracic extramedullary hematopoiesis in a patient with hereditary spherocytosis.
Extramedullary hematopoiesis (EMH) is a rare disorder, characterized by the appearance of hematopoietic elements outside of the bone marrow, which occurs in patients with chronic myeloproliferative disorders or congenital hemolytic anemias. We report on a 64-year-old man with hereditary spherocytosis, who presented with anemia, jaundice, intrathoracic EMH, and massive hemothorax. The diagnosis of EMH was established after computer tomography (CT)-guided punctuation of the paravertebral mass. The patient underwent splenectomy and thoracic drainage. After 1 year, the patient is in good health, with normal hemoglobin values, and hemothorax has not recurred.
