Granulocytic Sarcoma With Breast And Skin Presentation: A Report Of A Case Successfully Treated By Local Radiation And Systemic Chemotherapy

Granulocytic sarcoma (GS) is a rare extramedullary tumor composed of immature myeloid cells. It is usually associated with leukemia or other myeloproliferative disorders, but can also occur without overt hematologic disease, i.e. in patients with a normal bone marrow and no history of acute myelogenous leukemia. This primary extramedullary lesion may indeed represent a diagnostic and therapeutic dilemma for both the hematopathologist and oncologist. We describe a case of GS diagnosed in a nonleukemic patient and review the literature regarding the pathologic features and treatment of this condition. Copyright (C) 2000 S. Karger AG, Basel.
