title: An interesting presentation of intrathoracic extramedullary hematopoiesis in a patient with thalassemia intermedia.
abstract: Extramedullary hematopoiesis (EMH) occurs as a compensatory mechanism for bone marrow dysfunction in severe thalassemia. In addition to the more common locations, such as liver, spleen and lymph nodes, a mass of EMH may occasionally occur in the thorax. Intrathoracic EMH is usually asymptomatic. A 69-year-old woman who initially presented with hematuria, dysuria, and left inguinal pain was found to have paravertebral masses in the thorax. Histopathologic examination of a CT-guided needle aspiration biopsy of the masses showed the presence of trilineage hematopoiesis. We present this unusual case, in which EMH was diagnosed by chance in an elderly patient with no symptoms related to thalassemia.
