INTRODUCTION

Extramedullary myeloid cell tumor (granulocytic sarcoma, chloroma) is a rare cause of proptosis that can masquerade as lymphoma. Proper distinction between the two allows appropriate radiation dosing. We demonstrate in a 72-year-old man we saw with epiphora, proptosis, binocular diplopia, and pain in the right eye that extramedullary myeloid cell tumor may be treated with radiation alone using as little as 450-rad (4.5 Gy) applied in small fractions. This approach spares the elderly patient from the general myelosuppression of chemotherapy.

Report of a Case

An otherwise healthy 72-year-old man developed epiphora, proptosis, binocular diplopia, and pain in his right eye over an 8-month period. Ocular and medical histories were noncontributory. Visual acuity was 20/50 OD and 20/40 OS. External examination revealed right-sided hypoglobus, exophthalmos, and a ruddy, red bulbar conjunctiva associated with a large orbital mass that was firm to the touch and the mass did not perform retropulsion, instead when pushed it was . . .
