Cytodiagnosis of granulocytic sarcoma presenting as superior vena cava syndrome in acute myeloblastic leukemia. A case report.

Abstract

We describe a rare case of acute myeloblastic leukemia presenting with superior vena cava syndrome due to a mediastinal granulocytic sarcoma. The morphologic diagnosis of granulocytic sarcoma was obtained from computed tomography-guided fine needle aspiration cytology. This is the second such case described in the world literature.
