Abstract

PURPOSE
To report a case of primary extramedullary plasmacytoma which is rare in the orbit. METHODS: A 72 year-old man was referred for the evaluation of a slowly developing proptosis in the right eye. A CT scan revealed the orbital mass which involved optic nerve and surrounding tissues. Incisional biopsy via lower lid was performed. RESULTS: Histopathologic examination confirmed the findings of plasmacytoma. Systemic evaluation including bone marrow biopsy, clinical and radiologic evaluation showed no evidence for multiple myeloma. Taken together we diagnosed the orbital lesion as a primary extramedullary plasmacytoma. He was treated with radiation therapy and followed for 6months without evidence of new lesion or systemic disease. CONCLUSIONS: We experienced a case of primary extramedullary plasmacytoma which is rare in the orbit. Continuing careful observation is warranted because of its variable natural course and prognosis.
