Relapse of acute myeloid leukemia as isolated bilateral testicular granulocytic sarcoma in an adult.

Abstract

Received April 2007 Accepted September 2007 INTRODUCTION Acute myeloid leukemia (AML) is a malignant hematologic disease characterized by bone marrow infiltration with leukemic (blast) cells. Infiltration of extramedullary organs by these cells is called granulocytic sarcoma (GS). Relapsed AML with isolated testicular GS without bone marrow involvement is very rare and only a few cases have been reported.(1,2) We report a case of AML that relapsed as isolated bilateral testicular GS, 6.5 years after initial remission was induced by chemotherapy.
