PERICARDIAL EXTRAMEDULLARY HEMATOPOIESIS IN A NEONATE WITH CONGENITALHEART-DISEASE - A CASE-REPORT

A case of pericardial extramedullary hematopoiesis in a neonate with c ongenital heart disease was diagnosed by fine needle aspiration cytolo gy. Undifferentiated blasts, promyelocytes, metamyelocytes and nucleat ed red blood cells were evident in the pericardial fluid specimen. The differential diagnosis of bone marrow contamination of pericardial fl uid secondary to inadvertent sampling of neonatal hypodense bone tissu e is also discussed. To our knowledge, this is the first reported case of neonatal pericardial extramedullary hematopoiesis associated with congenital heart disease.
