Isolated myeloid sarcoma presenting in all four eyelids.

Myeloid sarcoma is an unusual manifestation of acute leukemia. These leukemic tumors have been described in multiple organ systems. Leukemia is almost always present, but may be undiagnosed when the myeloid sarcoma comes to medical attention. We present a clinicopathologic report of a previously healthy young woman with conjunctival myeloid sarcomas of all 4 eyelids without evidence of an underlying hematologic disorder over 15 months' follow-up, despite refusal of consolidation chemotherapy. Isolated, multifocal myeloid sarcoma of the periorbital region is a very rare manifestation of acute leukemia.
