Myeloid sarcoma of the orbit without systemic recurrence of disease in an adult: A clinicopathological case report

ABSTRACT

Myeloid sarcoma (MS), also known as granulocytic sarcoma (GS) or chloroma (named for the greenish hue attributed to the pigment of myeloperoxidase [MPO]), is a rare solid tumor with a predilection for the orbit. MS usually occurs in conjunction with acute myeloid leukemia (AML), myelodysplastic syndrome (MDS), or myeloproliferative disorder (MPS) and may be the harbinger of disease. Therefore, prompt diagnosis is essential for patient survival. We present a rare case of a 61 year old with an isolated orbital MS without active leukemia.
