Abstract

Myeloid sarcoma is a tumor mass of immature myeloid or monocytic cells (rarely erythroid or megakaryocytic) occurring in an extramedullary site. A de novo promyelocytic granulocytic sarcoma is a very rare tumor. We report a case of a young man presenting with a paraspinal myeloid sarcoma of promyelocytic origin.

Keywords: Granulocytic sarcoma; myeloid sarcoma; promyelocytic leukemia.
