Orbital Tumour as Initial Manifestation of Acute Myeloid Leukemia: Granulocytic Sarcoma: Case Report

[摘要] We report orbital involvement as an initial manifestation of acute myeloid leukemia in a 57-year-old woman. The patient presented with painful proptosis and limited ocular motility. Orbital computed tomography revealed bilateral homogeneous masses. Orbital biopsy was performed on the right side; and histopathology disclosed a myelocytic tumour. Despite treatment using irradiation and chemotherapy, the patient died eleven months after presentation. There appear to be only a few previous reports of acute myeloid leukemia cases presenting with orbital involvement, and most cases occurred in children. This very rare condition has a poor survival prognosis, even with radiation treatment and chemotherapy.
