Pulmonary extramedullary hematopoiesis presented as massive hemoptysis, a rare entity: A case report

Abstract

Extramedullary hematopoiesis occurs as a complication of hematological diseases such as myelofibrosis, sickle cell anemia and thalassemia. Extramedullary tissue usually consists of the liver, spleen and lymph nodes. Although it has been described to occur in almost every organ / region in the body, it is rarely reported in the thorax. Thoracic extramedullary hematopoiesis has been reported in the literature as paravertebral masses usually seen on chest radiography. In this report, we present a rare case of pulmonary extramedullary hematopoiesis in a 66-year-old male patient who did not have hematological or rheumatological comorbid disease and presented with hemoptysis.
