A Case of Multiple Cutaneous Granulocytic Sarcomas in an Elderly Patient

Abstract

Granulocytic sarcoma (GS) is an extramedullary tumor composed of malignant myeloid precursor cells. GS commonly presents in soft tissues of head, neck and in intracranial sites, but GS may arise anywhere in the body. The diagnosis is made clinically on the basis of a combination of location, pathologic appearance, and a concurrent diagnosis of acute leukemia or myelodysplastic syndrome (MDS). GS is generally presenting as a single lesion. We present an elderly patient with multiple cutaneous GS who has acute myelogenous leukemia (AML). Since GS often precedes leukemia, early recognition and a definitive diagnosis of GS is very important for proper and timely treatment.
