Abstract

Granulocytic sarcoma (GS) is a rare extramedullary tumor composed of immature myeloid precursor cells. GS is associated with acute or chronic myeloid leukemia; it has rarely been reported in non-leukemic patients. We report two cases of GS with unusual presentations; neither had bone marrow involvement. The first case was a GS presenting with multiple intra-abdominal masses in a 43-year-old man. Computed tomography (CT) of the abdomen showed masses in the small bowel and right adrenal gland. The second case was a patient with a GS presenting with symptoms of spinal cord compression in a 32-year-old man. Magnetic resonance imaging (MRI) showed an extradural mass in the spinal canal at the T3-T5 levels. Blood smear and bone marrow studies were normal. These cases show that GS should be included in the differential diagnosis of intra-abdominal masses and extradural spinal cord tumors, even in the absence of leukemia.
