Case Report on Primary Extramedullary Plasmacytoma Originating in the Lacrimal Gland

ABSTRACT

Most plasmacytomas originate from the bone marrow and only 3% of these tumors are from the soft tissues outside the bone marrow. Mean survival rate and clinical manifestations including metastasis and response to therapy are quite different from each other. Although both groups share plasma cell as their stem cell, these two groups are presumed to be different disease entities. The authors report a rare case of extramedullary plasmacytoma of lacrimal gland origin in a 42-year-old man who presented with painless proptosis.
